+Subject: block: Introduce bio_needs_zone_write_plugging()
+
+From: Damien Le Moal <dlemoal@kernel.org>
+
+commit f70291411ba20d50008db90a6f0731efac27872c upstream.
+
+In preparation for fixing device mapper zone write handling, introduce
+the inline helper function bio_needs_zone_write_plugging() to test if a
+BIO requires handling through zone write plugging using the function
+blk_zone_plug_bio(). This function returns true for any write
+(op_is_write(bio) == true) operation directed at a zoned block device
+using zone write plugging, that is, a block device with a disk that has
+a zone write plug hash table.
+
+This helper allows simplifying the check on entry to blk_zone_plug_bio()
+and used in to protect calls to it for blk-mq devices and DM devices.
+

+Subject: cifs: reset iface weights when we cannot find a candidate
+
+From: Shyam Prasad N <sprasad@microsoft.com>
+
+commit 9d5eff7821f6d70f7d1b4d8a60680fba4de868a7 upstream.
+
+We now do a weighted selection of server interfaces when allocating
+new channels. The weights are decided based on the speed advertised.
+The fulfilled weight for an interface is a counter that is used to
+track the interface selection. It should be reset back to zero once
+all interfaces fulfilling their weight.
+
+In cifs_chan_update_iface, this reset logic was missing. As a result
+when the server interface list changes, the client may not be able
+to find a new candidate for other channels after all interfaces have
+been fulfilled.
+

+
+From: Christian Marangi <ansuelsmth@gmail.com>
+
+commit 077ec7bcec9a8987d2a133afb7e13011878c7576 upstream.
+
+With the conversion done by commit e88f03230dc0 ("clk: qcom: gcc-ipq8074:
+rework nss_port5/6 clock to multiple conf") a Copy-Paste error was made
+for the nss_port6_tx_clk_src frequency table.
+
+This was caused by the wrong setting of the parent in
+ftbl_nss_port6_tx_clk_src that was wrongly set to P_UNIPHY1_RX instead
+of P_UNIPHY2_TX.
+
+This cause the UNIPHY2 port to malfunction when it needs to be scaled to
+higher clock. The malfunction was observed with the example scenario
+with an Aquantia 10G PHY connected and a speed higher than 1G (example
+2.5G)
+
+Fix the broken frequency table to restore original functionality.

+Subject: dm: Always split write BIOs to zoned device limits
+
+From: Damien Le Moal <dlemoal@kernel.org>
+
+commit 2df7168717b7d2d32bcf017c68be16e4aae9dd13 upstream.
+
+Any zoned DM target that requires zone append emulation will use the
+block layer zone write plugging. In such case, DM target drivers must
+not split BIOs using dm_accept_partial_bio() as doing so can potentially
+lead to deadlocks with queue freeze operations. Regular write operations
+used to emulate zone append operations also cannot be split by the
+target driver as that would result in an invalid writen sector value
+return using the BIO sector.
+
+In order for zoned DM target drivers to avoid such incorrect BIO
+splitting, we must ensure that large BIOs are split before being passed
+to the map() function of the target, thus guaranteeing that the
+limits for the mapped device are not exceeded.
+
+dm-crypt and dm-flakey are the only target drivers supporting zoned
+devices and using dm_accept_partial_bio().
+
+In the case of dm-crypt, this function is used to split BIOs to the
+internal max_write_size limit (which will be suppressed in a different
+patch). However, since crypt_alloc_buffer() uses a bioset allowing only
+up to BIO_MAX_VECS (256) vectors in a BIO. The dm-crypt device
+max_segments limit, which is not set and so default to BLK_MAX_SEGMENTS
+(128), must thus be respected and write BIOs split accordingly.
+
+In the case of dm-flakey, since zone append emulation is not required,
+the block layer zone write plugging is not used and no splitting of BIOs
+required.
+
+Modify the function dm_zone_bio_needs_split() to use the block layer
+helper function bio_needs_zone_write_plugging() to force a call to
+bio_split_to_limits() in dm_split_and_process_bio(). This allows DM
+target drivers to avoid using dm_accept_partial_bio() for write
+operations on zoned DM devices.

+Subject: ext4: fix largest free orders lists corruption on mb_optimize_scan switch
+
+From: Baokun Li <libaokun1@huawei.com>
+
+commit 7d345aa1fac4c2ec9584fbd6f389f2c2368671d5 upstream.
+
+The grp->bb_largest_free_order is updated regardless of whether
+mb_optimize_scan is enabled. This can lead to inconsistencies between
+grp->bb_largest_free_order and the actual s_mb_largest_free_orders list
+index when mb_optimize_scan is repeatedly enabled and disabled via remount.
+
+For example, if mb_optimize_scan is initially enabled, largest free
+order is 3, and the group is in s_mb_largest_free_orders[3]. Then,
+mb_optimize_scan is disabled via remount, block allocations occur,
+updating largest free order to 2. Finally, mb_optimize_scan is re-enabled
+via remount, more block allocations update largest free order to 1.
+
+At this point, the group would be removed from s_mb_largest_free_orders[3]
+under the protection of s_mb_largest_free_orders_locks[2]. This lock
+mismatch can lead to list corruption.
+
+To fix this, whenever grp->bb_largest_free_order changes, we now always
+attempt to remove the group from its old order list. However, we only
+insert the group into the new order list if `mb_optimize_scan` is enabled.
+This approach helps prevent lock inconsistencies and ensures the data in
+the order lists remains reliable.

+Subject: ext4: fix zombie groups in average fragment size lists
+
+From: Baokun Li <libaokun1@huawei.com>
+
+commit 1c320d8e92925bb7615f83a7b6e3f402a5c2ca63 upstream.
+
+Groups with no free blocks shouldn't be in any average fragment size list.
+However, when all blocks in a group are allocated(i.e., bb_fragments or
+bb_free is 0), we currently skip updating the average fragment size, which
+means the group isn't removed from its previous s_mb_avg_fragment_size[old]
+list.
+
+This created "zombie" groups that were always skipped during traversal as
+they couldn't satisfy any block allocation requests, negatively impacting
+traversal efficiency.
+
+Therefore, when a group becomes completely full, bb_avg_fragment_size_order
+is now set to -1. If the old order was not -1, a removal operation is
+performed; if the new order is not -1, an insertion is performed.

+Subject: ext4: initialize superblock fields in the kballoc-test.c kunit tests
+
+From: Zhang Yi <yi.zhang@huawei.com>
+
+commit 82e6381e23f1ea7a14f418215068aaa2ca046c84 upstream.
+
+Various changes in the "ext4: better scalability for ext4 block
+allocation" patch series have resulted in kunit test failures, most
+notably in the test_new_blocks_simple and the test_mb_mark_used tests.
+The root cause of these failures is that various in-memory ext4 data
+structures were not getting initialized, and while previous versions
+of the functions exercised by the unit tests didn't use these
+structure members, this was arguably a test bug.
+
+Since one of the patches in the block allocation scalability patches
+is a fix which is has a cc:stable tag, this commit also has a
+cc:stable tag.

+Subject: iommu/arm-smmu-qcom: Add SM6115 MDSS compatible
+
+From: Alexey Klimov <alexey.klimov@linaro.org>
+
+commit f7fa8520f30373ce99c436c4d57c76befdacbef3 upstream.
+
+Add the SM6115 MDSS compatible to clients compatible list, as it also
+needs that workaround.
+Without this workaround, for example, QRB4210 RB2 which is based on
+SM4250/SM6115 generates a lot of smmu unhandled context faults during
+boot:
+
+arm_smmu_context_fault: 116854 callbacks suppressed
+arm-smmu c600000.iommu: Unhandled context fault: fsr=0x402,
+iova=0x5c0ec600, fsynr=0x320021, cbfrsynra=0x420, cb=5
+arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420
+arm-smmu c600000.iommu: FSYNR0 = 00320021 [S1CBNDX=50 PNU PLVL=1]

+arm-smmu c600000.iommu: FSR = 00000402 [Format=2 TF], SID=0x420
+
+and also failed initialisation of lontium lt9611uxc, gpu and dpu is
+observed:
+(binding MDSS components triggered by lt9611uxc have failed)

+Subject: iommu/vt-d: Optimize iotlb_sync_map for non-caching/non-RWBF modes
+
+From: Lu Baolu <baolu.lu@linux.intel.com>
+
+commit 12724ce3fe1a3d8f30d56e48b4f272d8860d1970 upstream.
+
+The iotlb_sync_map iommu ops allows drivers to perform necessary cache
+flushes when new mappings are established. For the Intel iommu driver,
+this callback specifically serves two purposes:
+
+- To flush caches when a second-stage page table is attached to a device
+ whose iommu is operating in caching mode (CAP_REG.CM==1).
+- To explicitly flush internal write buffers to ensure updates to memory-
+ resident remapping structures are visible to hardware (CAP_REG.RWBF==1).
+
+However, in scenarios where neither caching mode nor the RWBF flag is
+active, the cache_tag_flush_range_np() helper, which is called in the
+iotlb_sync_map path, effectively becomes a no-op.
+
+Despite being a no-op, cache_tag_flush_range_np() involves iterating
+through all cache tags of the iommu's attached to the domain, protected
+by a spinlock. This unnecessary execution path introduces overhead,
+leading to a measurable I/O performance regression. On systems with NVMes
+under the same bridge, performance was observed to drop from approximately
+~6150 MiB/s down to ~4985 MiB/s.
+
+Introduce a flag in the dmar_domain structure. This flag will only be set
+when iotlb_sync_map is required (i.e., when CM or RWBF is set). The
+cache_tag_flush_range_np() is called only for domains where this flag is
+set. This flag, once set, is immutable, given that there won't be mixed
+configurations in real-world scenarios where some IOMMUs in a system
+operate in caching mode while others do not. Theoretically, the
+immutability of this flag does not impact functionality.

+Subject: iommufd: Prevent ALIGN() overflow
+
+From: Jason Gunthorpe <jgg@nvidia.com>
+
+commit b42497e3c0e74db061eafad41c0cd7243c46436b upstream.
+
+When allocating IOVA the candidate range gets aligned to the target
+alignment. If the range is close to ULONG_MAX then the ALIGN() can
+wrap resulting in a corrupted iova.
+
+Open code the ALIGN() using get_add_overflow() to prevent this.
+This simplifies the checks as we don't need to check for length earlier
+either.
+
+Consolidate the two copies of this code under a single helper.
+
+This bug would allow userspace to create a mapping that overlaps with some
+other mapping or a reserved range.

+Subject: misc: rtsx: usb: Ensure mmc child device is active when card is present
+
+From: Ricky Wu <ricky_wu@realtek.com>
+
+commit 966c5cd72be8989c8a559ddef8e8ff07a37c5eb0 upstream.
+
+When a card is present in the reader, the driver currently defers
+autosuspend by returning -EAGAIN during the suspend callback to
+trigger USB remote wakeup signaling. However, this does not guarantee
+that the mmc child device has been resumed, which may cause issues if
+it remains suspended while the card is accessible.
+This patch ensures that all child devices, including the mmc host
+controller, are explicitly resumed before returning -EAGAIN. This
+fixes a corner case introduced by earlier remote wakeup handling,
+improving reliability of runtime PM when a card is inserted.
+
+Fixes: 883a87ddf2f1 ("misc: rtsx_usb: Use USB remote wakeup signaling for card insertion detection")

+Subject: mm/damon/core: commit damos->target_nid
+
+From: Bijan Tabatabai <bijantabatab@micron.com>
+
+commit 579bd5006fe7f4a7abb32da0160d376476cab67d upstream.
+
+When committing new scheme parameters from the sysfs, the target_nid field
+of the damos struct would not be copied. This would result in the
+target_nid field to retain its original value, despite being updated in
+the sysfs interface.
+
+This patch fixes this issue by copying target_nid in damos_commit().

+
+From: Xinyu Liu <katieeliu@tencent.com>
+
+commit cf16f408364efd8a68f39011a3b073c83a03612d upstream.
+
+usb_parse_ss_endpoint_companion() checks descriptor type before length,
+enabling a potentially odd read outside of the buffer size.
+
+Fix this up by checking the size first before looking at any of the
+fields in the descriptor.

+Subject: usb: typec: ucsi: Update power_supply on power role change
+
+From: Myrrh Periwinkle <myrrhperiwinkle@qtmlabs.xyz>
+
+commit 7616f006db07017ef5d4ae410fca99279aaca7aa upstream.
+
+The current power direction of an USB-C port also influences the
+power_supply's online status, so a power role change should also update
+the power_supply.
+
+Fixes an issue on some systems where plugging in a normal USB device in
+for the first time after a reboot will cause upower to erroneously
+consider the system to be connected to AC power.
