Bug description:
[SRU Justification]
[Impact]
On some platforms, PS/2 keyboard cannot wake system up from s2idle.
[Fix]
Mainline commit cb1f65c1e142 ("PM: s2idle: ACPI: Fix wakeup interrupts
handling") picks up the missed wakeup interrupt.
[Test Case]
Use button press on PS/2 keyboard to wake suspended system.
[Where problems could occur]
It may still discard irqs under some very rare corner cases that are not
yet identified, but the implementation can be extended easily when
necessary.
[Other Info]
This affects 5.4+ kernels and has been proposed for linux-stable. While
this is merged in v5.17-rc4, linux-unstable will have this soon so
nomination is skipped.
========== original bug report ==========
With bug 1957026 and bug 1960434, suspend/resume using rtc and power
button work as expected, but PS/2 or USB keyboard still do not work
well as an wakeup source. This focus on fixes for PS/2.
