2023-03-21hwmon: fix potential sensor registration fail if of_node is missingPhinex Hung
It is not sufficient to check of_node in current device. In some cases, this would cause the sensor registration to fail. This patch looks for device's ancestors to find a valid of_node if any.

2023-03-21entry/rcu: Check TIF_RESCHED _after_ delayed RCU wake-upFrederic Weisbecker
RCU sometimes needs to perform a delayed wake up for specific kthreads handling offloaded callbacks (RCU_NOCB). These wakeups are performed by timers and upon entry to idle (also to guest and to user on nohz_full). However the delayed wake-up on kernel exit is actually performed after the thread flags are fetched towards the fast path check for work to do on exit to user. As a result, and if there is no other pending work to do upon that kernel exit, the current task will resume to userspace with TIF_RESCHED set and the pending wake up ignored. Fix this with fetching the thread flags _after_ the delayed RCU-nocb kthread wake-up.

2023-03-21perf/x86/amd/core: Always clear status for idxBreno Leitao
The variable 'status' (which contains the unhandled overflow bits) is not being properly masked in some cases, displaying the following warning: WARNING: CPU: 156 PID: 475601 at arch/x86/events/amd/core.c:972 amd_pmu_v2_handle_irq+0x216/0x270 This seems to be happening because the loop is being continued before the status bit being unset, in case x86_perf_event_set_period() returns 0. This is also causing an inconsistency because the "handled" counter is incremented, but the status bit is not cleaned. Move the bit cleaning together above, together when the "handled" counter is incremented.

Commit 829c1651e9c4 ("sched/fair: sanitize vruntime of entity being placed") fixes an overflowing bug, but ignore a case that se->exec_start is reset after a migration. For fixing this case, we delay the reset of se->exec_start after placing the entity which se->exec_start to detect long sleeping task.

2023-03-21entry: Fix noinstr warning in __enter_from_user_mode()Josh Poimboeuf
__enter_from_user_mode() is triggering noinstr warnings with CONFIG_DEBUG_PREEMPT due to its call of preempt_count_add() via ct_state(). The preemption disable isn't needed as interrupts are already disabled. And the context_tracking_enabled() check in ct_state() also isn't needed as that's already being done by the CT_WARN_ON(). Just use __ct_state() instead. Fixes the following warnings: vmlinux.o: warning: objtool: enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_enter_from_user_mode+0xf9: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: syscall_enter_from_user_mode_prepare+0xc7: call to preempt_count_add() leaves .noinstr.text section vmlinux.o: warning: objtool: irqentry_enter_from_user_mode+0xba: call to preempt_count_add() leaves .noinstr.text section Fixes: 171476775d32 ("context_tracking: Convert state to atomic_t") Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Link: https://lore.kernel.org/r/d8955fa6d68dc955dda19baf13ae014ae27926f5.1677369694.git.jpoimboe@kernel.org
2023-03-21drm: panel-orientation-quirks: Add quirk for Lenovo Yoga Book X90FHans de Goede
Like the Windows Lenovo Yoga Book X91F/L the Android Lenovo Yoga Book X90F/L has a portrait 1200x1920 screen used in landscape mode, add a quirk for this. When the quirk for the X91F/L was initially added it was written to also apply to the X90F/L but this does not work because the Android version of the Yoga Book uses completely different DMI strings. Also adjust the X91F/L quirk to reflect that it only applies to the X91F/L models.

The pipe may differ from crtc index if pipes are fused off. For testing purposes, IGT needs to know the pipe. There's already a I915_GET_PIPE_FROM_CRTC_ID IOCTL for this.

2023-03-20accel/habanalabs: do not verify engine modes after being changedKoby Elbaz
Engines idle state can't always be verified between changes of engine modes (e.g., stall/halt). For example, if a CS is inflight when altering engine's mode, idle state will return NOT idle, always.

Commit 45d9c8dde4cd ("drm/vgem: use shmem helpers") introduced shmem helpers to vgem and with that, removed all uses of the struct drm_vgem_gem_object. So, as the struct is no longer used, delete it.

2023-03-20drm/bridge: ti-tfp410: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
