Merge tag 'gpio-fixes-for-v5.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
- fix a regression in GPIO ACPI on HP ElitePad 1000 G2 where the
gpio_set_debounce_timeout() now returns a fatal error if the specific
debounce period is not supported by the driver instead of just
emitting a warning
- fix return values of irq_mask/unmask() callbacks in gpio-uniphier
- fix hwirq calculation in gpio-aspeed-sgpio
- fix two issues in gpio-rockchip: only make the extended debounce
support available for v2 and remove a redundant BIT() usage
* tag 'gpio-fixes-for-v5.15-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux:
gpio/rockchip: fix get_direction value handling
gpio/rockchip: extended debounce support is only available on v2
gpio: gpio-aspeed-sgpio: Fix wrong hwirq in irq handler.
gpio: uniphier: Fix void functions to remove return value
gpiolib: acpi: Make set-debounce-timeout failures non fatal

+ * ioctl(KVM_RUN) enters the guest so that TIF_NOTIFY_RESUME
+ * (or TIF_NEED_RESCHED, which indirectly leads to handling
+ * NOTIFY_RESUME) is handled in KVM context.
+ *
+ * If NOTIFY_RESUME/NEED_RESCHED is set after KVM enters
+ * the guest, the guest will trigger a IO/MMIO exit all the
+ * way to userspace and the TIF flags will be handled by
+ * the generic "exit to userspace" logic, not by KVM. The
+ * exit to userspace is necessary to give the test a chance
+ * to check the rseq CPU ID (see #2).
+ *
+ * Alternatively, guest_code() could include an instruction
+ * to trigger an exit that is handled by KVM, but any such
+ * exit requires architecture specific code.
+ *
+ * 2. To let ioctl(KVM_RUN) make its way back to the test
+ * before the next round of migration. The test's check on
+ * the rseq CPU ID must wait for migration to complete in
+ * order to avoid false positive, thus any kernel rseq bug
+ * will be missed if the next migration starts before the
+ * check completes.
+ *
+ * 3. To ensure the read-side makes efficient forward progress,
+ * e.g. if sched_getcpu() involves a syscall. Stalling the
+ * read-side means the test will spend more time waiting for
+ * sched_getcpu() to stabilize and less time trying to hit
+ * the timing-dependent bug.
+ *
+ * Because any bug in this area is likely to be timing-dependent,
+ * run with a range of delays at 1us intervals from 1us to 10us
+ * as a best effort to avoid tuning the test to the point where
+ * it can hit _only_ the original bug and not detect future
+ * regressions.
+ *
+ * The original bug can reproduce with a delay up to ~500us on
+ * x86-64, but starts to require more iterations to reproduce
+ * as the delay creeps above ~10us, and the average runtime of
+ * each iteration obviously increases as well. Cap the delay
+ * at 10us to keep test runtime reasonable while minimizing
+ * potential coverage loss.
+ *
+ * The lower bound for reproducing the bug is likely below 1us,
+ * e.g. failures occur on x86-64 with nanosleep(0), but at that
+ * point the overhead of the syscall likely dominates the delay.
+ * Use usleep() for simplicity and to avoid unnecessary kernel
