During disassociation we're decreasing the phy's ref count.
If the ref count becomes 0, we're configuring the phy ctxt
to the default channel (the lowest channel which the device
can operate on). Currently we're not checking whether the
the default channel is enabled or not. Fix it by configuring
the phy ctxt to the lowest channel which is enabled.
Currently, fragmented EBS was set for a channel only if the 'hb_type'
was set to fragmented or balanced scan. However, 'hb_type' is set only
in case of CDB, and thus fragmented EBS is never set for a channel for
non-CDB devices. Fix it.
The quirk handling may need to set some different properties
which means using a different swnode, move the setting of the swnode
to inside dwc3_pci_quirks() so that the quirk handling can choose
a different swnode.
Normally, the queues are disabled when the channels are deactivated, and
enabled when the channels are activated. However, on register, the
channels are not active, but the queues are enabled by default. This
change fixes it, preventing mlx5e_xmit from running when the channels
are deactivated in the beginning.
[why]
In LTTPR non-transparent mode, we need
to reset the cached lane settings before performing
link training on the next PHY repeater. Otherwise,
the cached lane settings will be used for the next
clock recovery e.g. VS = MAX (3) which should not be
the case according to the DP specs. We expect to use
minimum lane settings on each clock recovery sequence.
[how]
Reset DPCD and HW lane settings on each repeater LT.
Set training pattern to 0 for the repeater that failed LT
at the proper place.

The AXP288's recommended and factory default Vhold value (minimum
input voltage below which the input current draw will be reduced)
is 4.4V. This lines up with other charger IC's such as the TI
bq2419x/bq2429x series which use 4.36V or 4.44V.
For some reason some BIOS-es initialize Vhold to 4.6V or even 4.7V
which combined with the typical voltage drop over typically low
wire gauge micro-USB cables leads to the input-current getting
capped below 1A (with a 2A capable dedicated charger) based on Vhold.
This leads to slow charging, or even to the device slowly discharging
if the device is in heavy use.
As the Linux AXP288 drivers use the builtin BC1.2 charger detection
and send the input-current-limit according to the detected charger
there really is no reason not to use the recommended 4.4V Vhold.
Set Vhold to 4.4V to fix the slow charging issue on various devices.
There is one exception, the special-case of the HP X2 2-in-1s which
combine this BC1.2 capable PMIC with a Type-C port and a 5V/3A factory
provided charger with a Type-C plug which does not do BC1.2. These
have their input-current-limit hardcoded to 3A (like under Windows)
and use a higher Vhold on purpose to limit the current when used
with other chargers. To avoid touching Vhold on these HP X2 laptops
the code setting Vhold is added to an else branch of the if checking
for these models.
Note this also fixes the sofar unused VBUS_ISPOUT_VHOLD_SET_MASK
define, which was wrong.

Commit 1f9ad21c3b38 ("powerpc/mm: Implement set_memory() routines")
included a spin_lock() to change_page_attr() in order to
safely perform the three step operations. But then
commit 9f7853d7609d ("powerpc/mm: Fix set_memory_*() against
concurrent accesses") modify it to use pte_update() and do
the operation safely against concurrent access.
In the meantime, Maxime reported some spinlock recursion.
Remove the read / modify / write sequence to make the operation atomic
and remove the spin_lock() in change_page_attr().
To do the operation atomically, we can't use pte modification helpers
anymore. Because all platforms have different combination of bits, it
is not easy to use those bits directly. But all have the
_PAGE_KERNEL_{RO/ROX/RW/RWX} set of flags. All we need it to compare
two sets to know which bits are set or cleared.
For instance, by comparing _PAGE_KERNEL_ROX and _PAGE_KERNEL_RO you
know which bit gets cleared and which bit get set when changing exec
permission.
The driver is missing to set the residual size while completing an

removed the need to disable bottom half while acquiring
listening_hash.lock. There are still two callers left which disable
bottom half before the lock is acquired.
On PREEMPT_RT the softirqs are preemptible and local_bh_disable() acts
as a lock to ensure that resources, that are protected by disabling
bottom halves, remain protected.
This leads to a circular locking dependency if the lock acquired with
disabled bottom halves is also acquired with enabled bottom halves
followed by disabling bottom halves. This is the reverse locking order.
It has been observed with inet_listen_hashbucket::lock:
Drop local_bh_disable() around __inet_hash() which acquires
listening_hash->lock. Split inet_unhash() and acquire the
listen_hashbucket lock without disabling bottom halves; the inet_ehash
lock with disabled bottom halves.
The copy test uses the memcpy() to copy data between IO memory spaces.
This can trigger an alignment fault error (pasted the error logs below)
because memcpy() may use unaligned accesses on a mapped memory that is
just IO, which does not support unaligned memory accesses.
Fix it by using the correct memcpy API to copy from/to IO memory.
Userspace can specify which events a guest is allowed to use with the
KVM_ARM_VCPU_PMU_V3_FILTER attribute. The list of allowed events can be
identified by a guest from reading the PMCEID{0,1}_EL0 registers.
Changing the PMU event filter after a VCPU has run can cause reads of the
registers performed before the filter is changed to return different values
than reads performed with the new event filter in place. The architecture
defines the two registers as read-only, and this behaviour contradicts
that.
Keep track when the first VCPU has run and deny changes to the PMU event
filter to prevent this from happening.

During event processing, events are read from the event queue one
by one until the queue is empty.If the master device continuously
requests address access at the same time and the SMMU generates
events, the cyclic processing of the event takes a long time and
softlockup warnings may be reported.
Aardvark hardware supports Multi-MSI and MSI_FLAG_MULTI_PCI_MSI is already
set for the MSI chip. But when allocating MSI interrupt numbers for
Multi-MSI, the numbers need to be properly aligned, otherwise endpoint
devices send MSI interrupt with incorrect numbers.
Fix this issue by using function bitmap_find_free_region() instead of
bitmap_find_next_zero_area().
To ensure that aligned MSI interrupt numbers are used by endpoint devices,
we cannot use Linux virtual irq numbers (as they are random and not
properly aligned). Instead we need to use the aligned hwirq numbers.
This change fixes receiving MSI interrupts on Armada 3720 boards and
allows using NVMe disks which use Multi-MSI feature with 3 interrupts.
Without this NVMe disks freeze booting as linux nvme-core.c is waiting
60s for an interrupt.

On large config LPARs (having 192 and more cores), Linux fails to boot
due to insufficient memory in the first memblock. It is due to the
memory reservation for the crash kernel which starts at 128MB offset of
the first memblock. This memory reservation for the crash kernel doesn't
leave enough space in the first memblock to accommodate other essential
system resources.
The crash kernel start address was set to 128MB offset by default to
ensure that the crash kernel get some memory below the RMA region which
is used to be of size 256MB. But given that the RMA region size can be
512MB or more, setting the crash kernel offset to mid of RMA size will
leave enough space for the kernel to allocate memory for other system
resources.
Since the above crash kernel offset change is only applicable to the LPAR
platform, the LPAR feature detection is pushed before the crash kernel
reservation. The rest of LPAR specific initialization will still
be done during pseries_probe_fw_features as usual.
This patch is dependent on changes to paca allocation for boot CPU. It
expect boot CPU to discover 1T segment support which is introduced by
the patch posted here:

While testing a patch that will follow later
("net: add netns refcount tracker to struct nsproxy")
I found that devtmpfs_init() was called before init_net
was initialized.
This is a bug, because devtmpfs_setup() calls
ksys_unshare(CLONE_NEWNS);
This has the effect of increasing init_net refcount,
which will be later overwritten to 1, as part of setup_net(&init_net)
We had too many prior patches [1] trying to work around the root cause.
Really, make sure init_net is in BSS section, and that net_ns_init()
is called earlier at boot time.
Note that another patch ("vfs: add netns refcount tracker
to struct fs_context") also will need net_ns_init() being called
before vfs_caches_init()
As a bonus, this patch saves around 4KB in .data section.

The above failure is due to different printouts for some ABS
versioned symbols. For example, with the same libbpf.so,
$ /bin/readelf --dyn-syms --wide tools/lib/bpf/libbpf.so | grep "LIBBPF" | grep ABS
134: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS LIBBPF_0.5.0

134: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS LIBBPF_0.5.0@@LIBBPF_0.5.0
202: 0000000000000000 0 OBJECT GLOBAL DEFAULT ABS LIBBPF_0.6.0@@LIBBPF_0.6.0
...
The binutils readelf doesn't print out the symbol LIBBPF_* version and llvm-readelf does.
Such a difference caused libbpf build failure with llvm-readelf.
The proposed fix filters out all ABS symbols as they are not part of the comparison.
This works for both binutils readelf and llvm-readelf.

As stated in [1], negative current values are used for discharging
batteries.
AXP PMICs internally have two different ADC channels for shunt current
measurement: one used during charging and one during discharging.
The values reported by these ADCs are unsigned.
While the driver properly selects ADC channel to get the data from,
it doesn't apply negative sign when reporting discharging current.

Menglong Dong reports that the documentation for the dst_port field in
struct bpf_sock is inaccurate and confusing. From the BPF program PoV, the
field is a zero-padded 16-bit integer in network byte order. The value
appears to the BPF user as if laid out in memory as so:
32-, 16-, and 8-bit wide loads from the field are all allowed, but only if
the offset into the field is 0.
32-bit wide loads from dst_port are especially confusing. The loaded value,
after converting to host byte order with bpf_ntohl(dst_port), contains the
port number in the upper 16-bits.
Remove the confusion by splitting the field into two 16-bit fields. For
backward compatibility, allow 32-bit wide loads from offsetof(struct
bpf_sock, dst_port).
While at it, allow loads 8-bit loads at offset [0] and [1] from dst_port.
pm_runtime_get_sync() will increase the rumtime PM counter
even when it returns an error. Thus a pairing decrement is needed
to prevent refcount leak. Fix this by replacing this API with
pm_runtime_resume_and_get(), which will not change the runtime
PM counter on error. Besides, a matching decrement is needed
on the error handling path to keep the counter balanced.
According to the man page of TCP_CORK [1], if set, don't send out
partial frames. All queued partial frames are sent when option is
cleared again.
When applications call setsockopt to disable TCP_CORK, this call is
protected by lock_sock(), and tries to mod_delayed_work() to 0, in order
to send pending data right now. However, the delayed work smc_tx_work is
also protected by lock_sock(). There introduces lock contention for
sending data.
To fix it, send pending data directly which acts like TCP, without
lock_sock() protected in the context of setsockopt (already lock_sock()ed),
and cancel unnecessary dealyed work, which is protected by lock.

If amss.bin was missing ath11k would crash during 'rmmod ath11k_pci'. The
reason for that was that we were using mhi_async_power_up() which does not
check any errors. But mhi_sync_power_up() on the other hand does check for
errors so let's use that to fix the crash.
I was not able to find a reason why an async version was used.
ath11k_mhi_start() (which enables state ATH11K_MHI_POWER_ON) is called from
ath11k_hif_power_up(), which can sleep. So sync version should be safe to use

The issue here is that board file loading happens after ath11k_pci_probe()

Improve non-desktop quirk logging if the EDID indicates non-desktop. If
both are set, note about redundant quirk. If there's no quirk but the
EDID indicates non-desktop, don't log non-desktop is set to 0.
Now that there is support for the Microsoft VSDB for HMDs, remove the
non-desktop quirk for two devices that are verified to contain it in
their EDID: HPN-3515 and LEN-B800.
Presumably most of the other Windows Mixed Reality headsets contain it
as well, but there are ACR-7FCE and SEC-5194 devices without it.
[Why]
For allow eDP hot-plug feature, the stream signal may change to VIRTUAL
when plug-out and back to eDP when plug-in. OS will still setPathMode
with same timing for each plugging, but eDP gets no stream update as we
don't check signal type changing back as keeping it VIRTUAL. It's also
unsafe for future cases that stream signal is switched with same timing.
[How]
Check stream signal type change include previous HDMI signal case.

The bug was found during fuzzing. Stacktrace locates it in
ath5k_eeprom_convert_pcal_info_5111.
When none of the curve is selected in the loop, idx can go
up to AR5K_EEPROM_N_PD_CURVES. The line makes pd out of bound.
pd = &chinfo[pier].pd_curves[idx];
There are many OOB writes using pd later in the code. So I
added a sanity check for idx. Checks for other loops involving
AR5K_EEPROM_N_PD_CURVES are not needed as the loop index is not
used outside the loops.
The patch is NOT tested with real device.
The following is the fuzzing report

When RDTSCP is supported but RDPID is not supported in host,
RDPID emulation is available. However, __kvm_get_msr() would
only fail when RDTSCP/RDPID both are disabled in guest, so
the emulator wouldn't inject a #UD when RDPID is disabled but
RDTSCP is enabled in guest.
HSW_IN_TX* bits are used in generic code which are not supported on
AMD. Worse, these bits overlap with AMD EventSelect[11:8] and hence
using HSW_IN_TX* bits unconditionally in generic code is resulting in
unintentional pmu behavior on AMD. For example, if EventSelect[11:8]
is 0x2, pmc_reprogram_counter() wrongly assumes that
HSW_IN_TX_CHECKPOINTED is set and thus forces sampling period to be 0.
Also per the SDM, both bits 32 and 33 "may only be set if the processor
supports HLE or RTM" and for "IN_TXCP (bit 33): this bit may only be set
for IA32_PERFEVTSEL2."
Opportunistically eliminate code redundancy, because if the HSW_IN_TX*
bit is set in pmc->eventsel, it is already set in attr.config.

AMD EPYC CPUs never raise a #GP for a WRMSR to a PerfEvtSeln MSR. Some
reserved bits are cleared, and some are not. Specifically, on
Zen3/Milan, bits 19 and 42 are not cleared.
When emulating such a WRMSR, KVM should not synthesize a #GP,
regardless of which bits are set. However, undocumented bits should
not be passed through to the hardware MSR. So, rather than checking
for reserved bits and synthesizing a #GP, just clear the reserved
bits.
This may seem pedantic, but since KVM currently does not support the
"Host/Guest Only" bits (41:40), it is necessary to clear these bits
rather than synthesizing #GP, because some popular guests (e.g Linux)
will set the "Host Only" bit even on CPUs that don't support
EFER.SVME, and they don't expect a #GP.

Commit 6dce5aa59e0b ("PCI: xgene: Use inbound resources for setup")
killed PCIe on my XGene-1 box (a Mustang board). The machine itself
is still alive, but half of its storage (over NVMe) is gone, and the
NVMe driver just times out.
Note that this machine boots with a device tree provided by the
UEFI firmware (2016 vintage), which could well be non conformant
with the spec, hence the breakage.
With the patch reverted, the box boots 5.17-rc8 with flying colors.

FNAME(cmpxchg_gpte) is an inefficient mess. It is at least decent if it
can go through get_user_pages_fast(), but if it cannot then it tries to
use memremap(); that is not just terribly slow, it is also wrong because
it assumes that the VM_PFNMAP VMA is contiguous.
The right way to do it would be to do the same thing as
hva_to_pfn_remapped() does since commit add6a0cd1c5b ("KVM: MMU: try to
fix up page faults before giving up", 2016-07-05), using follow_pte()
and fixup_user_fault() to determine the correct address to use for
memremap(). To do this, one could for example extract hva_to_pfn()
for use outside virt/kvm/kvm_main.c. But really there is no reason to
do that either, because there is already a perfectly valid address to
do the cmpxchg() on, only it is a userspace address. That means doing
user_access_begin()/user_access_end() and writing the code in assembly
to handle exceptions correctly. Worse, the guest PTE can be 8-byte
even on i686 so there is the extra complication of using cmpxchg8b to
account for. But at least it is an efficient mess.
(Thanks to Linus for suggesting improvement on the inline assembly).

Ice driver tries to always create XDP rings array to be
num_possible_cpus() sized, regardless of user's queue count setting that
can be changed via ethtool -L for example.
Currently, ice_tx_xsk_pool() calculates the qid by decrementing the
ring->q_index by the count of XDP queues, but ring->q_index is set to 'i
+ vsi->alloc_txq'.
When user did ethtool -L $IFACE combined 1, alloc_txq is 1, but
vsi->num_xdp_txq is still num_possible_cpus(). Then, ice_tx_xsk_pool()
will do OOB access and in the final result ring would not get xsk_pool
pointer assigned. Then, each ice_xsk_wakeup() call will fail with error
and it will not be possible to get into NAPI and do the processing from
driver side.
Fix this by decrementing vsi->alloc_txq instead of vsi->num_xdp_txq from
ring-q_index in ice_tx_xsk_pool() so the calculation is reflected to the
setting of ring->q_index.
For the case when xp_alloc_batch() is used but the batched allocation
cannot be used, there is a slow path that uses the non-batched
xp_alloc(). When it fails to allocate an entry, it returns NULL. The
current code wrote this NULL into the entry of the provided results
array (pointer to the driver SW ring usually) and returned. This might
not be what the driver expects and to make things simpler, just write
successfully allocated xdp_buffs into the SW ring,. The driver might
have information in there that is still important after an allocation
failure.
Note that at this point in time, there are no drivers using
xp_alloc_batch() that could trigger this slow path. But one might get
added.

According to subdevice interface specification found in V4L2 API
documentation, set format pad operations should not affect image
geometry set in preceding image processing steps. Unfortunately, that
requirement is not respected by the driver implementation of set format
as it was not the case when that code was still implementing a pair of
now obsolete .s_mbus_fmt() / .try_mbus_fmt() video operations before
they have been merged and reused as an implementation of .set_fmt() pad
operation by commit 717fd5b4907a ("[media] v4l2: replace try_mbus_fmt
by set_fmt").
Exclude non-compliant crop rectangle adjustments from set format try,
as well as a call to .set_selection() from set format active processing
path, so only frame scaling is applied as needed and crop rectangle is
no longer modified.

Try requests are now only supported by format processing pad operations
implemented by the driver. The driver selection API operations
currently respond to them with -EINVAL. While that is correct, it
constraints video device drivers to not use subdevice cropping at all
while processing user requested active frame size, otherwise their set
try format results might differ from active. As a consequence, we
can't fix set format pad operation as not to touch crop rectangle since
that would affect users not being able to set arbitrary frame sizes.
Moreover, without a working set try selection support we are not able
to use pad config crop rectangle as a reference while processing set
try format requests.
Implement missing try selection support. Moreover, as it will be now
possible to maintain the pad config crop rectangle via selection API,
start using it instead of the active one as a reference while
processing set try format requests.
is_unscaled_ok() helper, now also called from set selection operation,
has been just moved up in the source file to avoid a prototype, with no

larb@16010000: 'mediatek,larb-id' is a required property
arch/arm64/boot/dts/mediatek/mt8167-pumpkin.dt.yaml
As the description of mediatek,larb-id, the property is only
required when the larbid is not consecutive from its IOMMU point of view.
Also, from the description of mediatek,larbs in
Documentation/devicetree/bindings/iommu/mediatek,iommu.yaml, all the larbs
must sort by the larb index.
In mt8167, there is only one IOMMU HW and three larbs. The drivers already
know its larb index from the mediatek,larbs property of IOMMU, thus no
need this property.

('link-frequencies', 'data-lanes' were unexpected)
From schema: Documentation/devicetree/bindings/media/i2c/hynix,hi846.yaml
The interrupt property is not mandatory at all, this property should not
be part of the required properties list, so move it into the optional
properties list.

while properties in the children nodes are specific to the NAND
*chip*. This error was already present during the yaml conversion.
