2023-02-22arm64: Reset KASAN tag in copy_highpage with HW tags onlyPeter Collingbourne
During page migration, the copy_highpage function is used to copy the page data to the target page. If the source page is a userspace page with MTE tags, the KASAN tag of the target page must have the match-all tag in order to avoid tag check faults during subsequent accesses to the page by the kernel. However, the target page may have been allocated in a number of ways, some of which will use the KASAN allocator and will therefore end up setting the KASAN tag to a non-match-all tag. Therefore, update the target page's KASAN tag to match the source page. We ended up unintentionally fixing this issue as a result of a bad merge conflict resolution between commit e059853d14ca ("arm64: mte: Fix/clarify the PG_mte_tagged semantics") and commit 20794545c146 ("arm64: kasan: Revert "arm64: mte: reset the page tag in page->flags""), which preserved a tag reset for PG_mte_tagged pages which was considered to be unnecessary at the time. Because SW tags KASAN uses separate tag storage, update the code to only reset the tags when HW tags KASAN is enabled.

2023-02-22swiotlb: mark swiotlb_memblock_alloc() as __initRandy Dunlap
swiotlb_memblock_alloc() calls memblock_alloc(), which calls (__init) memblock_alloc_try_nid(). However, swiotlb_membloc_alloc() can be marked as __init since it is only called by swiotlb_init_remap(), which is already marked as __init. This prevents a modpost build warning/error: WARNING: modpost: vmlinux.o: section mismatch in reference: swiotlb_memblock_alloc (section: .text) -> memblock_alloc_try_nid (section: .init.text) WARNING: modpost: vmlinux.o: section mismatch in reference: swiotlb_memblock_alloc (section: .text) -> memblock_alloc_try_nid (section: .init.text) This fixes the build warning/error seen on ARM64, PPC64, S390, i386, and x86_64.

2023-02-22backlight: pwm_bl: Don't rely on a disabled PWM emiting inactive stateUwe Kleine-König
Most but not all PWMs drive the PWM pin to its inactive state when disabled. However if there is no enable_gpio and no regulator the PWM must drive the inactive state to actually disable the backlight. So keep the PWM on in this case. Note that to determine if there is a regulator some effort is required because it might happen that there isn't actually one but the regulator core gave us a dummy. (A nice side effect is that this makes the regulator actually optional even on fully constrained systems.) This fixes backlight disabling e.g. on i.MX6 when an inverted PWM is used. Hint for the future: If this change results in a regression, the bug is in the lowlevel PWM driver.

2023-02-22backlight: pwm_bl: Configure pwm only once per backlight toggleUwe Kleine-König
When the function pwm_backlight_update_status() was called with brightness > 0, pwm_get_state() was called twice (once directly and once in compute_duty_cycle). Also pwm_apply_state() was called twice (once in pwm_backlight_power_on() and once directly). Optimize this to do both calls only once. Note that with this affects the order of regulator and PWM setup. It's not expected to have a relevant effect on hardware. The rationale for this is that the regulator (and the GPIO) are reasonable to switch in pwm_backlight_power_on()/pwm_backlight_power_off() but the PWM has nothing to do with power. (The post_pwm_on_delay and pwm_off_delay are still there though.)

When ath11k runs into internal errors upon suspend, it returns an error code to pci_pm_suspend, which aborts the entire system suspend. The driver should not abort system suspend, but should keep its internal errors to itself, and allow the system to suspend. Otherwise, a user can suspend a laptop by closing the lid and sealing it into a case, assuming that is will suspend, rather than heating up and draining the battery when in transit. In practice, the ath11k device seems to have plenty of transient errors, and subsequent suspend cycles after this failure often succeed. https://bugzilla.kernel.org/show_bug.cgi?id=216968 Fixes: d1b0c33850d29 ("ath11k: implement suspend for QCA6390 PCI devices") Signed-off-by: Len Brown <len.brown@intel.com> Cc: stable@vger.kernel.org Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://lore.kernel.org/r/20230201183201.14431-1-len.brown@intel.com

2023-02-22mfd: syscon: Allow reset control for syscon devicesJeremy Kerr
Simple syscon devices may require deassertion of a reset signal in order to access their register set. Rather than requiring a custom driver to implement this, we can use the generic "resets" specifiers to link a reset line to the syscon. This change adds an optional reset line to the syscon device description, and deasserts the reset if detected.

2023-02-22dt-bindings: mfd/syscon: Add resets propertyJeremy Kerr
Simple syscon devices may require deassertion of a reset signal in order to access their register set. This change adds the `resets` property from reset.yaml#/properties/resets (referenced through core.yaml), specifying a maxItems of 1 for a single (optional) reset descriptor. This will allow a future change to the syscon driver to implement reset control.
