+Subject: hrtimers: Unconditionally update target CPU base after offline timer migration
+
+From: Xiongfeng Wang <wangxiongfeng2@huawei.com>
+
+commit e895f8e29119c8c966ea794af9e9100b10becb88 upstream.
+
+When testing softirq based hrtimers on an ARM32 board, with high resolution
+mode and NOHZ inactive, softirq based hrtimers fail to expire after being
+moved away from an offline CPU:
+
+CPU0 CPU1
+ hrtimer_start(..., HRTIMER_MODE_SOFT);
+cpu_down(CPU1) ...
+ hrtimers_cpu_dying()
+ // Migrate timers to CPU0
+ smp_call_function_single(CPU0, returgger_next_event);
+ retrigger_next_event()
+ if (!highres && !nohz)
+ return;
+
+As retrigger_next_event() is a NOOP when both high resolution timers and
+NOHZ are inactive CPU0's hrtimer_cpu_base::softirq_expires_next is not
+updated and the migrated softirq timers never expire unless there is a
+softirq based hrtimer queued on CPU0 later.
+
+Fix this by removing the hrtimer_hres_active() and tick_nohz_active() check
+in retrigger_next_event(), which enforces a full update of the CPU base.
+As this is not a fast path the extra cost does not matter.

+
+From: Christoffer Sandberg <cs@tuxedo.de>
+
+commit 1939a9fcb80353dd8b111aa1e79c691afbde08b4 upstream.
+
+Occasionally wakes up from suspend with missing input on the internal
+keyboard. Setting the quirks appears to fix the issue for this device as
+well.

+Subject: Input: iqs7222 - avoid enabling unused interrupts
+
+From: Jeff LaBundy <jeff@labundy.com>
+
+commit c9ddc41cdd522f2db5d492eda3df8994d928be34 upstream.
+
+If a proximity event node is defined so as to specify the wake-up
+properties of the touch surface, the proximity event interrupt is
+enabled unconditionally. This may result in unwanted interrupts.
+
+Solve this problem by enabling the interrupt only if the event is
+mapped to a key or switch code.
