[ Upstream commit c5510b8d ] If CONFIG_GPOILIB is not set, the stub of gpio_to_desc() should return the same type of error as regular version: NULL. All the callers compare the return value of gpio_to_desc() against NULL, so returned ERR_PTR would be treated as non-error case leading to dereferencing of error value.

[ Upstream commit 92f45ebe ] The PCAL_PINCTRL_MASK is too large. The extended register block on PCAL6524, which is the largest chip with this block, has the block limited to address range 0x40..0x7f. This is because the bit 7 in the command register is used for the Address Increment functionality. Trim the mask to 0x60 to match the datasheet and to prevent accidental overwrite of the AI bit.

[ Upstream commit 0916224e ] When removing the driver, the following flow can happen: 1. host command is in progress, for example at index 68. 2. RX interrupt is received with the response. 3. Before it is processed, the remove flow kicks in, and calls iwl_pcie_txq_unmap. The function cleans all DMA, and promotes the read pointer to 69. 4. RX thread proceeds with the processing, and is calling iwl_pcie_cmdq_reclaim, which will print this error: iwl_pcie_cmdq_reclaim: Read index for DMA queue txq id (0), index 4 is out of range [0-256] 69 69. Detect this situation, and avoid the print. Change it to warning while at it, to make such issues more noticeable in the future. Signed-off-by:

[ Upstream commit 7bc24682 ] When traffic load is not low or low latency is active, TCM schedules re-evaluation work so in case traffic stops TCM will detect that traffic load has become low or that low latency is no longer active. However, if TCM is paused when the re-evaluation work runs, it does not re-evaluate and the re-evaluation work is no longer scheduled. As a result, TCM will not indicate that low latency is no longer active or that traffic load is low when traffic stops. Fix this by forcing TCM re-evaluation when TCM is resumed in case low latency is active or traffic load is not low. Signed-off-by:

[ Upstream commit 64866e5d ] This function is only half-used by mvm (i.e. only the nvm_version part matters, since the calibration version is irrelevant), so it's pointless to export it from iwlwifi. If mvm uses this function, it has the additional complexity of setting the calib version to a bogus value on all cfg structs. To avoid this, move the function to dvm and make a simple comparison of the nvm_version in mvm instead. Signed-off-by:

[ Upstream commit 4722a3e6 ] This commit fixes some build issues. The first issue is the breakage of linux.bin.ub target since commit ece97f3a ("microblaze: Fix simpleImage format generation") because the addition of UIMAGE_{IN,OUT} affected it. make ARCH=microblaze CROSS_COMPILE=microblaze-linux- linux.bin.ub [ snip ] OBJCOPY arch/microblaze/boot/linux.bin UIMAGE arch/microblaze/boot/linux.bin.ub.ub /usr/bin/mkimage: Can't open arch/microblaze/boot/linux.bin.ub: No such file or directory make[1]: *** [arch/microblaze/boot/Makefile;14: arch/microblaze/boot/linux.bin.ub] Error 1 make: *** [arch/microblaze/Makefile;83: linux.bin.ub] Error 2 The second issue is the use of the "if_changed" multiple times for the same target. As commit 92a47286 ("x86/boot: Fix if_changed build flip/flop bug") pointed out, this never works properly. Moreover, generating multiple images as a side-effect is confusing. Let's split the build recipe for each image. simpleImage.<dt>*.unstrip is just a copy of vmlinux. simpleImage.<dt> and simpleImage.<dt>.ub are created in the same way as linux.bin and linux.bin.ub, respectively. I kept simpleImage.* recipes independent of linux.bin.* ones to not change the behavior. Lastly, this commit fixes "make ARCH=microblaze clean". Previously, it only cleaned up the unstrip image. Now, all the simpleImage files are cleaned. Signed-off-by:

[ Upstream commit 0ac6b8fb ] CRYPTO_MSG_GETALG in NLM_F_DUMP mode sometimes doesn't return all registered crypto algorithms, because it doesn't support incremental dumps. crypto_dump_report() only permits itself to be called once, yet the netlink subsystem allocates at most ~64 KiB for the skb being dumped to. Thus only the first recvmsg() returns data, and it may only include a subset of the crypto algorithms even if the user buffer passed to recvmsg() is large enough to hold all of them. Fix this by using one of the arguments in the netlink_callback structure to keep track of the current position in the algorithm list. Then userspace can do multiple recvmsg() on the socket after sending the dump request. This is the way netlink dumps work elsewhere in the kernel; it's unclear why this was different (probably just an oversight). Also fix an integer overflow when calculating the dump buffer size hint.

[ Upstream commit 42a87d41 ] Until now there is no way to reset a AP queue or card. Driving a card or queue offline and online again does only toggle the 'software' online state. The only way to trigger a (hardware) reset is by running hot-unplug/hot-plug for example on the HMC. This patch makes the queue reset attribute in sysfs writable. Writing into this attribute triggers a reset on the AP queue's state machine. So the AP queue is flushed and state machine runs through the initial states which cause a reset (PQAP(RAPQ)) and a re-registration to interrupts (PQAP(AQIC)) if available. The reset sysfs attribute is writable by root only. So only an administrator is allowed to initiate a reset of AP queues. Please note that the queue's counter values are left untouched by the reset.

[ Upstream commit cb5b7262 ] When boxes are run near (or to) OOM, we have a problem with the discard page allocation in nvme. If we fail allocating the special page, we return busy, and it'll get retried. But since ordering is honored for dispatch requests, we can keep retrying this same IO and failing. Behind that IO could be requests that want to free memory, but they never get the chance. Allocate a fixed discard page per controller for a safe fallback, and use that if the initial allocation fails. Signed-off-by:

[ Upstream commit 1a2fa02f ] Ignore acpi_device_fix_up_power() return value. If we return an error we end up with acpi_default_enumeration() still creating a platform- device for the device and we end up with the device still being used but without the special LPSS related handling which is not useful. Specicifically ignoring the error fixes the touchscreen no longer working after a suspend/resume on a Prowise PT301 tablet. This tablet has a broken _PS0 method on the touchscreen's I2C controller, causing acpi_device_fix_up_power() to fail, causing fallback to standard platform-dev handling and specifically causing acpi_lpss_save/restore_ctx to not run. The I2C controllers _PS0 method does actually turn on the device, but then does some more nonsense which fails when run during early boot trying to use I2C opregion handling on another not-yet registered I2C controller.

[ Upstream commit 43feeea8 ] A log recovery failure has been reproduced where a symlink inode has a zero length in extent form. It was caused by a shutdown during a combined fstress+fsmark workload. The underlying problem is the issue in xfs_inactive_symlink(): the inode is unlocked between the symlink inactivation/truncation and the inode being freed. This opens a window for the inode to be written to disk before it xfs_ifree() removes it from the unlinked list, marks it free in the inobt and zeros the mode. For shortform inodes, the fix is simple. xfs_ifree() clears the data fork state, so there's no need to do it in xfs_inactive_symlink(). This means the shortform fork verifier will not see a zero length data fork as it mirrors the inode size through to xfs_ifree()), and hence if the inode gets written back and the fork verifiers are run they will still see a fork that matches the on-disk inode size. For extent form (remote) symlinks, it is a little more tricky. Here we explicitly set the inode size to zero, so the above race can lead to zero length symlinks on disk. Because the inode is unlinked at this point (i.e. on the unlinked list) and unreferenced, it can never be seen again by a user. Hence when we set the inode size to zeor, also change the type to S_IFREG. xfs_ifree() expects S_IFREG inodes to be of zero length, and so this avoids all the problems of zero length symlinks ever hitting the disk. It also avoids the problem of needing to handle zero length symlink inodes in log recovery to replay the extent free intents and the remaining deferops to free the extents the symlink used. Also add a couple of asserts to warn us if zero length symlinks end up in either the symlink create or inactivation paths. Signed-off-by:

[ Upstream commit 7faa313f ] Commit 39624469 ("arm64: preempt: Provide our own implementation of asm/preempt.h") extended the preempt count field in struct thread_info to 64 bits, so that it consists of a 32-bit count plus a 32-bit flag indicating whether or not the current task needs rescheduling. Whilst the asm-offsets definition of TSK_TI_PREEMPT was updated to point to this new field, the assembly usage was left untouched meaning that a 32-bit load from TSK_TI_PREEMPT on a big-endian machine actually returns the reschedule flag instead of the count. Whilst we could fix this by pointing TSK_TI_PREEMPT at the count field, we're actually better off reworking the two assembly users so that they operate on the whole 64-bit value in favour of inspecting the thread flags separately in order to determine whether a reschedule is needed.

[ Upstream commit a96a33b1 ] For cases where there is a mismatch in ARMv8.2-LVA support between CPUs we have to be careful in allowing secondary CPUs to boot if 52-bit virtual addresses have already been enabled on the boot CPU. This patch adds code to the secondary startup path. If the boot CPU has enabled 52-bit VAs then ID_AA64MMFR2_EL1 is checked to see if the secondary can also enable 52-bit support. If not, the secondary is prevented from booting and an error message is displayed indicating why. Technically this patch could be implemented using the cpufeature code when considering 52-bit userspace support. However, we employ low level checks here as the cpufeature code won't be able to run if we have mismatched 52-bit kernel va support. Signed-off-by:
