Subject: Fix for rtc driver boot breakage in 6.0.y
Date: Tue, 20 Dec 2022 01:12:23 +0100	[thread overview]
Message-ID: <Y6D958DeurSuoCuY@paranoid-android> (raw)

	Hello stable team and Greg,

There are 3 commits in Linus' tree for the rtc driver which should be
merged against stable 6.0.y (they're already in 6.1 / 6.1.y).

Without the first two, a x86-64 machine might panic during boot (Mel saw
a 50% chance of panic at boot - 5 out of 10 tries - and my experience
was identical).
https://lore.kernel.org/linux-acpi/20221010141630.zfzi7mk7zvnmclzy@techsingularity.net/

And after applying the first two, the kernel will not compile anymore
on non ACPI platform, so you need a third one.

The first two commits:

commit 4919d3eb2ec0ee364f7e3cf2d99646c1b224fae8
Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Date:   Wed Oct 12 20:07:01 2022 +0200

    rtc: cmos: Fix event handler registration ordering issue

commit 0782b66ed2fbb035dda76111df0954515e417b24
Author: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Date:   Tue Oct 18 18:09:31 2022 +0200

    rtc: cmos: Fix wake alarm breakage

And the third one:

commit db4e955ae333567dea02822624106c0b96a2f84f
Author: Alexandre Belloni <alexandre.belloni@bootlin.com>
Date:   Tue Oct 18 22:35:11 2022 +0200

    rtc: cmos: fix build on non-ACPI platforms

Cheers,
