+
+From: Stephan Gerhold <stephan@gerhold.net>
+
+commit cc1ec484f2d0f464ad11b56fe3de2589c23f73ec upstream.
+
+Add the missing vio-supply to all usages of the AW2013 LED controller
+to ensure that the regulator needed for pull-up of the interrupt and
+I2C lines is really turned on. While this seems to have worked fine so
+far some of these regulators are not guaranteed to be always-on. For
+example, pm8916_l6 is typically turned off together with the display
+if there aren't any other devices (e.g. sensors) keeping it always-on.

+Subject: arm64: dts: qcom: msm8916: Make blsp_dma controlled-remotely
+
+From: Stephan Gerhold <stephan@gerhold.net>
+
+commit 7c45b6ddbcff01f9934d11802010cfeb0879e693 upstream.
+
+The blsp_dma controller is shared between the different subsystems,
+which is why it is already initialized by the firmware. We should not
+reinitialize it from Linux to avoid potential other users of the DMA
+engine to misbehave.
+
+In mainline this can be described using the "qcom,controlled-remotely"
+property. In the downstream/vendor kernel from Qualcomm there is an
+opposite "qcom,managed-locally" property. This property is *not* set
+for the qcom,sps-dma@7884000 [1] so adding "qcom,controlled-remotely"
+upstream matches the behavior of the downstream/vendor kernel.
+
+Adding this seems to fix some weird issues with UART where both
+input/output becomes garbled with certain obscure firmware versions on
+some devices.

+
+From: Johan Hovold <johan+linaro@kernel.org>
+
+commit 663affdb12b3e26c77d103327cf27de720c8117e upstream.
+
+The sc8280xp Display Port PHYs can be used in either DP or eDP mode and
+this is configured using the devicetree compatible string which defaults
+to DP mode in the SoC dtsi.
+
+Override the default compatible string for the CRD eDP PHY node so that
+the eDP settings are used.

+Subject: arm64: dts: rockchip: Fix rk3588 USB power-domain clocks
+
+From: Sam Edwards <cfsworks@gmail.com>
+
+commit 44de8996ed5a10f08f2fe947182da6535edcfae5 upstream.
+
+The QoS blocks saved/restored when toggling the PD_USB power domain are
+clocked by ACLK_USB. Attempting to access these memory regions without
+that clock running will result in an indefinite CPU stall.
+
+The PD_USB node wasn't specifying this clock dependency, resulting in
+hangs when trying to toggle the power domain (either on or off), unless
+we get "lucky" and have ACLK_USB running for another reason at the time.
+This "luck" can result from the bootloader leaving USB powered/clocked,
+and if no built-in driver wants USB, Linux will disable the unused
+PD+CLK on boot when {pd,clk}_ignore_unused aren't given. This can also
+be unlucky because the two cleanup tasks run in parallel and race: if
+the CLK is disabled first, the PD deactivation stalls the boot. In any
+case, the PD cannot then be reenabled (if e.g. the driver loads later)
+once the clock has been stopped.
+
+Fix this by specifying a dependency on ACLK_USB, instead of only
+ACLK_USB_ROOT. The child-parent relationship means the former implies
+the latter anyway.

+
+From: Josef Bacik <josef@toxicpanda.com>
+
+commit 7b21ed7d119dc06b0ed2ba3e406a02cafe3a8d03 upstream.
+
+If you select CONFIG_EFI_ZBOOT, we will generate vmlinuz.efi, and then
+when we go to install the kernel we'll install the vmlinux instead
+because install.sh only recognizes Image.gz as wanting the compressed
+install image. With CONFIG_EFI_ZBOOT we don't get the proper kernel
+installed, which means it doesn't boot, which makes for a very confused
+and subsequently angry kernel developer.
+
+Fix this by properly installing our compressed kernel if we've enabled
+CONFIG_EFI_ZBOOT.

+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+commit 7d4b5d7a37bdd63a5a3371b988744b060d5bb86f upstream.
+
+In preparation for subsequent changes, introduce a specialized variant
+of async_schedule_dev() that will not invoke the argument function
+synchronously when it cannot be scheduled for asynchronous execution.
+
+The new function, async_schedule_dev_nocall(), will be used for fixing
+possible deadlocks in the system-wide power management core code.

+Subject: async: Split async_schedule_node_domain()
+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+commit 6aa09a5bccd8e224d917afdb4c278fc66aacde4d upstream.
+
+In preparation for subsequent changes, split async_schedule_node_domain()
+in two pieces so as to allow the bottom part of it to be called from a
+somewhat different code path.
+
+No functional impact.

+
+commit eff9704f5332a13b08fbdbe0f84059c9e7051d5f upstream.
+
+Though we do check the event ring read pointer by "is_valid_ring_ptr"
+to make sure it is in the buffer range, but there is another risk the
+pointer may be not aligned. Since we are expecting event ring elements
+are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer
+could lead to multiple issues like DoS or ring buffer memory corruption.
+
+So add a alignment check for event ring read pointer.

+Protect WP accesses such that multiple threads queueing buffers for

+
+Meanwhile, if CONFIG_TRACE_IRQFLAGS is enabled, irq will be enabled once

+
+Ensure read and write locks for the channel are not taken in succession by

+When the mpi_ec_ctx structure is initialized, some fields are not

+Subject: erofs: fix lz4 inplace decompression
+
+From: Gao Xiang <hsiangkao@linux.alibaba.com>
+
+commit 3c12466b6b7bf1e56f9b32c366a3d83d87afb4de upstream.
+
+Currently EROFS can map another compressed buffer for inplace
+decompression, that was used to handle the cases that some pages of
+compressed data are actually not in-place I/O.
+
+However, like most simple LZ77 algorithms, LZ4 expects the compressed
+data is arranged at the end of the decompressed buffer and it
+explicitly uses memmove() to handle overlapping:
+ __________________________________________________________
+ |_ direction of decompression --> ____ |_ compressed data _|
+
+Although EROFS arranges compressed data like this, it typically maps two
+individual virtual buffers so the relative order is uncertain.
+Previously, it was hardly observed since LZ4 only uses memmove() for
+short overlapped literals and x86/arm64 memmove implementations seem to
+completely cover it up and they don't have this issue. Juhyung reported
+that EROFS data corruption can be found on a new Intel x86 processor.
+After some analysis, it seems that recent x86 processors with the new
+FSRM feature expose this issue with "rep movsb".
+
+Let's strictly use the decompressed buffer for lz4 inplace
+decompression for now. Later, as an useful improvement, we could try
+to tie up these two buffers together in the correct order.

+Subject: ext4: allow for the last group to be marked as trimmed
+
+From: Suraj Jitindar Singh <surajjs@amazon.com>
+
+commit 7c784d624819acbeefb0018bac89e632467cca5a upstream.
+
+The ext4 filesystem tracks the trim status of blocks at the group
+level. When an entire group has been trimmed then it is marked as
+such and subsequent trim invocations with the same minimum trim size
+will not be attempted on that group unless it is marked as able to be
+trimmed again such as when a block is freed.
+
+Currently the last group can't be marked as trimmed due to incorrect
+logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
+to return the zero based index of the last cluster in a group. This is
+then used by ext4_try_to_trim_range() to determine if the trim
+operation spans the entire group and as such if the trim status of the
+group should be recorded.
+
+ext4_last_grp_cluster() takes a 0 based group index, thus the valid
+values for grp are 0..(ext4_get_groups_count - 1). Any group index
+less than (ext4_get_groups_count - 1) is not the last group and must
+have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
+to calculate the number of clusters based on the number of blocks in
+the group. Finally subtract 1 from the number of clusters as zero
+based indexing is expected. Rearrange the function slightly to make
+it clear what we are calculating and returning.
+
+Reproducer:
+// Create file system where the last group has fewer blocks than
+// blocks per group
+$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
+$ mount /dev/nvme0n1 /mnt
+
+Before Patch:
+$ fstrim -v /mnt
+/mnt: 25.9 MiB (27156480 bytes) trimmed
+// Group not marked as trimmed so second invocation still discards blocks
+$ fstrim -v /mnt
+/mnt: 25.9 MiB (27156480 bytes) trimmed
+
+After Patch:
+fstrim -v /mnt
+/mnt: 25.9 MiB (27156480 bytes) trimmed
+// Group marked as trimmed so second invocation DOESN'T discard any blocks
+fstrim -v /mnt
+/mnt: 0 B (0 bytes) trimmed
+
+Fixes: 45e4ab320c9b ("ext4: move setting of trimmed bit into ext4_try_to_trim_range()")

+Subject: hwrng: core - Fix page fault dead lock on mmap-ed hwrng
+
+From: Herbert Xu <herbert@gondor.apana.org.au>
+
+commit 78aafb3884f6bc6636efcc1760c891c8500b9922 upstream.
+
+There is a dead-lock in the hwrng device read path. This triggers
+when the user reads from /dev/hwrng into memory also mmap-ed from
+/dev/hwrng. The resulting page fault triggers a recursive read
+which then dead-locks.
+
+Fix this by using a stack buffer when calling copy_to_user.

+Subject: mips: Fix max_mapnr being uninitialized on early stages
+
+From: Serge Semin <fancer.lancer@gmail.com>
+
+commit e1a9ae45736989c972a8d1c151bc390678ae6205 upstream.
+
+max_mapnr variable is utilized in the pfn_valid() method in order to
+determine the upper PFN space boundary. Having it uninitialized
+effectively makes any PFN passed to that method invalid. That in its turn
+causes the kernel mm-subsystem occasion malfunctions even after the
+max_mapnr variable is actually properly updated. For instance,
+pfn_valid() is called in the init_unavailable_range() method in the
+framework of the calls-chain on MIPS:
+setup_arch()
++-> paging_init()
+ +-> free_area_init()
+ +-> memmap_init()
+ +-> memmap_init_zone_range()
+ +-> init_unavailable_range()
+
+Since pfn_valid() always returns "false" value before max_mapnr is
+initialized in the mem_init() method, any flatmem page-holes will be left
+in the poisoned/uninitialized state including the IO-memory pages. Thus
+any further attempts to map/remap the IO-memory by using MMU may fail.
+In particular it happened in my case on attempt to map the SRAM region.
+The kernel bootup procedure just crashed on the unhandled unaligned access
+bug raised in the __update_cache() method:
+
+> Unhandled kernel unaligned access[#1]:
+> CPU: 0 PID: 1 Comm: swapper/0 Not tainted 6.7.0-rc1-XXX-dirty #2056
+> ...
+> Call Trace:
+> [<8011ef9c>] __update_cache+0x88/0x1bc

+> [<80889d20>] platform_probe+0x68/0xec
+> ...
+
+Let's fix the problem by initializing the max_mapnr variable as soon as
+the required data is available. In particular it can be done right in the
+paging_init() method before free_area_init() is called since all the PFN
+zone boundaries have already been calculated by that time.

+commit 828f6df1bcba7f64729166efc7086ea657070445 upstream.
+
+The current logic is probably fine but is a bit convoluted. Plus, we
+don't want partial pages to be part of the sequential operation just in
+case the core would optimize the page read with a subpage read (which
+would break the sequence). This may happen on the first and last page
+only, so if the start offset or the end offset is not aligned with a
+page boundary, better avoid them to prevent any risk.

+
+commit 7c9414c870c027737d0f2ed7b0ed10f26edb1c61 upstream.
+
+A couple of reports pointed at some strange failures happening a bit
+randomly since the introduction of sequential page reads support. After
+investigation it turned out the most likely reason for these issues was
+the fact that sometimes a (longer) read might happen, starting at the
+same page that was read previously. This is optimized by the raw NAND
+core, by not sending the READ_PAGE command to the NAND device and just
+reading out the data in a local cache. When this page is also flagged as
+being the starting point for a sequential read, it means the page right
+next will be accessed without the right instructions. The NAND chip will
+be confused and will not output correct data. In order to avoid such
+situation from happening anymore, we can however handle this case with a
+bit of additional logic, to postpone the initialization of the read
+sequence by one page.

+
+The ONFI specification states that devices do not need to support
+sequential reads across LUN boundaries. In order to prevent such event
+from happening and possibly failing, let's introduce the concept of
+"pause" in the sequential read to handle these cases. The first/last
+pages remain the same but any time we cross a LUN boundary we will end
+and restart (if relevant) the sequential read operation.

+Subject: OPP: Pass rounded rate to _set_opp()
+
+From: Viresh Kumar <viresh.kumar@linaro.org>
+
+commit 7269c250db1b89cda72ca419b7bd5e37997309d6 upstream.
+
+The OPP core finds the eventual frequency to set with the help of
+clk_round_rate() and the same was earlier getting passed to _set_opp()
+and that's what would get configured.
+
+The commit 1efae8d2e777 ("OPP: Make dev_pm_opp_set_opp() independent of
+frequency") mistakenly changed that. Fix it.

+Subject: parisc/firmware: Fix F-extend for PDC addresses
+
+From: Helge Deller <deller@gmx.de>
+
+commit 735ae74f73e55c191d48689bd11ff4a06ea0508f upstream.
+
+When running with narrow firmware (64-bit kernel using a 32-bit
+firmware), extend PDC addresses into the 0xfffffff0.00000000
+region instead of the 0xf0f0f0f0.00000000 region.
+
+This fixes the power button on the C3700 machine in qemu (64-bit CPU
+with 32-bit firmware), and my assumption is that the previous code was
+really never used (because most 64-bit machines have a 64-bit firmware),
+or it just worked on very old machines because they may only decode
+40-bit of virtual addresses.

+
+From: Christian Marangi <ansuelsmth@gmail.com>
+
+commit 08e23d05fa6dc4fc13da0ccf09defdd4bbc92ff4 upstream.
+
+Fix buffer overflow in trans_stat_show().
+
+Convert simple snprintf to the more secure scnprintf with size of
+PAGE_SIZE.
+
+Add condition checking if we are exceeding PAGE_SIZE and exit early from
+loop. Also add at the end a warning that we exceeded PAGE_SIZE and that
+stats is disabled.
+
+Return -EFBIG in the case where we don't have enough space to write the
+full transition table.
+
+Also document in the ABI that this function can return -EFBIG error.

+Subject: PM: hibernate: Enforce ordering during image compression/decompression
+
+From: Hongchen Zhang <zhanghongchen@loongson.cn>
+
+commit 71cd7e80cfde548959952eac7063aeaea1f2e1c6 upstream.
+
+An S4 (suspend to disk) test on the LoongArch 3A6000 platform sometimes
+fails with the following error messaged in the dmesg log:
+
+ Invalid LZO compressed length
+
+That happens because when compressing/decompressing the image, the
+synchronization between the control thread and the compress/decompress/crc
+thread is based on a relaxed ordering interface, which is unreliable, and the
+following situation may occur:
+
+CPU 0 CPU 1
+save_image_lzo lzo_compress_threadfn
+ atomic_set(&d->stop, 1);
+ atomic_read(&data[thr].stop)
+ data[thr].cmp = data[thr].cmp_len;
+ WRITE data[thr].cmp_len
+
+Then CPU0 gets a stale cmp_len and writes it to disk. During resume from S4,
+wrong cmp_len is loaded.
+
+To maintain data consistency between the two threads, use the acquire/release
+variants of atomic set and read operations.
+

+Subject: PM: sleep: Fix possible deadlocks in core system-wide PM code
+
+From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
+
+commit 7839d0078e0d5e6cc2fa0b0dfbee71de74f1e557 upstream.
+
+It is reported that in low-memory situations the system-wide resume core
+code deadlocks, because async_schedule_dev() executes its argument
+function synchronously if it cannot allocate memory (and not only in
+that case) and that function attempts to acquire a mutex that is already
+held. Executing the argument function synchronously from within
+dpm_async_fn() may also be problematic for ordering reasons (it may
+cause a consumer device's resume callback to be invoked before a
+requisite supplier device's one, for example).
+
+Address this by changing the code in question to use
+async_schedule_dev_nocall() for scheduling the asynchronous
+execution of device suspend and resume functions and to directly
+run them synchronously if async_schedule_dev_nocall() returns false.

+Subject: powerpc/ps3_defconfig: Disable PPC64_BIG_ENDIAN_ELF_ABI_V2
+
+From: Geoff Levand <geoff@infradead.org>
+
+commit 482b718a84f08b6fc84879c3e90cc57dba11c115 upstream.
+
+Commit 8c5fa3b5c4df ("powerpc/64: Make ELFv2 the default for big-endian
+builds"), merged in Linux-6.5-rc1 changes the calling ABI in a way
+that is incompatible with the current code for the PS3's LV1 hypervisor
+calls.
+
+This change just adds the line '# CONFIG_PPC64_BIG_ENDIAN_ELF_ABI_V2 is not set'
+to the ps3_defconfig file so that the PPC64_ELF_ABI_V1 is used.
+
+Fixes run time errors like these:
+
+ BUG: Kernel NULL pointer dereference at 0x00000000
+ Faulting instruction address: 0xc000000000047cf0
+ Oops: Kernel access of bad area, sig: 11 [#1]
+ Call Trace:
+ [c0000000023039e0] [c00000000100ebfc] ps3_create_spu+0xc4/0x2b0 (unreliable)

+Subject: s390/vfio-ap: always filter entire AP matrix
+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit 850fb7fa8c684a4c6bf0e4b6978f4ddcc5d43d11 upstream.
+
+The vfio_ap_mdev_filter_matrix function is called whenever a new adapter or
+domain is assigned to the mdev. The purpose of the function is to update
+the guest's AP configuration by filtering the matrix of adapters and
+domains assigned to the mdev. When an adapter or domain is assigned, only
+the APQNs associated with the APID of the new adapter or APQI of the new
+domain are inspected. If an APQN does not reference a queue device bound to
+the vfio_ap device driver, then it's APID will be filtered from the mdev's
+matrix when updating the guest's AP configuration.
+
+Inspecting only the APID of the new adapter or APQI of the new domain will
+result in passing AP queues through to a guest that are not bound to the
+vfio_ap device driver under certain circumstances. Consider the following:
+
+guest's AP configuration (all also assigned to the mdev's matrix):
+14.0004
+14.0005
+14.0006
+16.0004
+16.0005
+16.0006
+
+unassign domain 4
+unbind queue 16.0005
+assign domain 4
+
+When domain 4 is re-assigned, since only domain 4 will be inspected, the
+APQNs that will be examined will be:
+14.0004
+16.0004
+
+Since both of those APQNs reference queue devices that are bound to the
+vfio_ap device driver, nothing will get filtered from the mdev's matrix
+when updating the guest's AP configuration. Consequently, queue 16.0005
+will get passed through despite not being bound to the driver. This
+violates the linux device model requirement that a guest shall only be
+given access to devices bound to the device driver facilitating their
+pass-through.
+
+To resolve this problem, every adapter and domain assigned to the mdev will
+be inspected when filtering the mdev's matrix.

+Subject: s390/vfio-ap: do not reset queue removed from host config
+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit b9bd10c43456d16abd97b717446f51afb3b88411 upstream.
+
+When a queue is unbound from the vfio_ap device driver, it is reset to
+ensure its crypto data is not leaked when it is bound to another device
+driver. If the queue is unbound due to the fact that the adapter or domain
+was removed from the host's AP configuration, then attempting to reset it
+will fail with response code 01 (APID not valid) getting returned from the
+reset command. Let's ensure that the queue is assigned to the host's
+configuration before resetting it.

+Subject: s390/vfio-ap: let on_scan_complete() callback filter matrix and update guest's APCB
+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit 774d10196e648e2c0b78da817f631edfb3dfa557 upstream.
+
+When adapters and/or domains are added to the host's AP configuration, this
+may result in multiple queue devices getting created and probed by the
+vfio_ap device driver. For each queue device probed, the matrix of adapters
+and domains assigned to a matrix mdev will be filtered to update the
+guest's APCB. If any adapters or domains get added to or removed from the
+APCB, the guest's AP configuration will be dynamically updated (i.e., hot
+plug/unplug). To dynamically update the guest's configuration, its VCPUs
+must be taken out of SIE for the period of time it takes to make the
+update. This is disruptive to the guest's operation and if there are many
+queues probed due to a change in the host's AP configuration, this could be
+troublesome. The problem is exacerbated by the fact that the
+'on_scan_complete' callback also filters the mdev's matrix and updates
+the guest's AP configuration.
+
+In order to reduce the potential amount of disruption to the guest that may
+result from a change to the host's AP configuration, let's bypass the
+filtering of the matrix and updating of the guest's AP configuration in the
+probe callback - if due to a host config change - and defer it until the
+'on_scan_complete' callback is invoked after the AP bus finishes its device
+scan operation. This way the filtering and updating will be performed only
+once regardless of the number of queues added.

+Subject: s390/vfio-ap: loop over the shadow APCB when filtering guest's AP configuration
+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit 16fb78cbf56e42b8efb2682a4444ab59e32e7959 upstream.
+
+While filtering the mdev matrix, it doesn't make sense - and will have
+unexpected results - to filter an APID from the matrix if the APID or one
+of the associated APQIs is not in the host's AP configuration. There are
+two reasons for this:
+
+1. An adapter or domain that is not in the host's AP configuration can be
+ assigned to the matrix; this is known as over-provisioning. Queue
+ devices, however, are only created for adapters and domains in the
+ host's AP configuration, so there will be no queues associated with an
+ over-provisioned adapter or domain to filter.
+
+2. The adapter or domain may have been externally removed from the host's
+ configuration via an SE or HMC attached to a DPM enabled LPAR. In this
+ case, the vfio_ap device driver would have been notified by the AP bus
+ via the on_config_changed callback and the adapter or domain would
+ have already been filtered.
+
+Since the matrix_mdev->shadow_apcb.apm and matrix_mdev->shadow_apcb.aqm are
+copied from the mdev matrix sans the APIDs and APQIs not in the host's AP
+configuration, let's loop over those bitmaps instead of those assigned to
+the matrix.

+Subject: s390/vfio-ap: reset queues associated with adapter for queue unbound from driver
+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit f009cfa466558b7dfe97f167ba1875d6f9ea4c07 upstream.
+
+When a queue is unbound from the vfio_ap device driver, if that queue is
+assigned to a guest's AP configuration, its associated adapter is removed
+because queues are defined to a guest via a matrix of adapters and
+domains; so, it is not possible to remove a single queue.
+
+If an adapter is removed from the guest's AP configuration, all associated
+queues must be reset to prevent leaking crypto data should any of them be
+assigned to a different guest or device driver. The one caveat is that if
+the queue is being removed because the adapter or domain has been removed
+from the host's AP configuration, then an attempt to reset the queue will
+fail with response code 01, AP-queue number not valid; so resetting these
+queues should be skipped.

+
+From: Tony Krowiak <akrowiak@linux.ibm.com>
+
+commit f848cba767e59f8d5c54984b1d45451aae040d50 upstream.
+
+When filtering the adapters from the configuration profile for a guest to
+create or update a guest's AP configuration, if the APID of an adapter and
+the APQI of a domain identify a queue device that is not bound to the
+vfio_ap device driver, the APID of the adapter will be filtered because an
+individual APQN can not be filtered due to the fact the APQNs are assigned
+to an AP configuration as a matrix of APIDs and APQIs. Consequently, a
+guest will not have access to all of the queues associated with the
+filtered adapter. If the queues are subsequently made available again to
+the guest, they should re-appear in a reset state; so, let's make sure all
+queues associated with an adapter unplugged from the guest are reset.
+
+In order to identify the set of queues that need to be reset, let's allow a
+vfio_ap_queue object to be simultaneously stored in both a hashtable and a
+list: A hashtable used to store all of the queues assigned
+to a matrix mdev; and/or, a list used to store a subset of the queues that
+need to be reset. For example, when an adapter is hot unplugged from a
+guest, all guest queues associated with that adapter must be reset. Since
+that may be a subset of those assigned to the matrix mdev, they can be
+stored in a list that can be passed to the vfio_ap_mdev_reset_queues
+function.

+Subject: s390/vfio-ap: unpin pages on gisc registration failure
+
+From: Anthony Krowiak <akrowiak@linux.ibm.com>
+
+commit 7b2d039da622daa9ba259ac6f38701d542b237c3 upstream.
+
+In the vfio_ap_irq_enable function, after the page containing the
+notification indicator byte (NIB) is pinned, the function attempts
+to register the guest ISC. If registration fails, the function sets the
+status response code and returns without unpinning the page containing
+the NIB. In order to avoid a memory leak, the NIB should be unpinned before
+returning from the vfio_ap_irq_enable function.

+Subject: soc: fsl: cpm1: qmc: Fix __iomem addresses declaration
+
+From: Herve Codina <herve.codina@bootlin.com>
+
+commit a5ec3a21220da06bdda2e686012ca64fdb6c513d upstream.
+
+Running sparse (make C=1) on qmc.c raises a lot of warning such as:
+ ...
+ warning: incorrect type in assignment (different address spaces)
+ expected struct cpm_buf_desc [usertype] *[noderef] __iomem bd
+ got struct cpm_buf_desc [noderef] [usertype] __iomem *txbd_free
+ ...
+
+Indeed, some variable were declared 'type *__iomem var' instead of
+'type __iomem *var'.
+
+Use the correct declaration to remove these warnings.
+
+Fixes: 3178d58e0b97 ("soc: fsl: cpm1: Add support for QMC")

+Subject: soc: fsl: cpm1: qmc: Fix rx channel reset
+
+From: Herve Codina <herve.codina@bootlin.com>
+
+commit dfe66d012af2ddfa566cf9c860b8472b412fb7e4 upstream.
+
+The qmc_chan_reset_rx() set the is_rx_stopped flag. This leads to an
+inconsistent state in the following sequence.
+ qmc_chan_stop()
+ qmc_chan_reset()
+Indeed, after the qmc_chan_reset() call, the channel must still be
+stopped. Only a qmc_chan_start() call can move the channel from stopped
+state to started state.
+
+Fix the issue removing the is_rx_stopped flag setting from
+qmc_chan_reset()

+Subject: soc: fsl: cpm1: tsa: Fix __iomem addresses declaration
+
+From: Herve Codina <herve.codina@bootlin.com>
+
+commit fc0c64154e5ddeb6f63c954735bd646ce5b8d9a4 upstream.
+
+Running sparse (make C=1) on tsa.c raises a lot of warning such as:
+ --- 8< ---
+ warning: incorrect type in assignment (different address spaces)
+ expected void *[noderef] si_regs
+ got void [noderef] __iomem *
+ --- 8< ---
+
+Indeed, some variable were declared 'type *__iomem var' instead of
+'type __iomem *var'.
+
+Use the correct declaration to remove these warnings.

+Subject: soc: qcom: pmic_glink_altmode: fix port sanity check
+
+From: Johan Hovold <johan+linaro@kernel.org>
+
+commit c4fb7d2eac9ff9bfc35a2e4d40c7169a332416e0 upstream.
+
+The PMIC GLINK altmode driver currently supports at most two ports.
+
+Fix the incomplete port sanity check on notifications to avoid
+accessing and corrupting memory beyond the port array if we ever get a
+notification for an unsupported port.
