Bug Description

SRU Justification:

[Impact]
The mantic kernel introduced a regression in atomic operations on arm64
which causes all kinds of problems including file system corruptions,
since commit "locking/atomic: scripts: restructure fallback
ifdeffery".

An example report of people encountering this in UTM with a arm64
generic kernel: https://github.com/utmapp/UTM/issues/4840

[Fix]
Cherry-pick commit "locking/atomic: scripts: fix fallback ifdeffery"
from linux-stable v6.5.6

[Test Plan]

Boot test on an arm64 vm.

[Where problems could occur]
Since this is touching atomic operations, this has a wide impact on the
kernel.

This bug is awaiting verification that the linux/6.5.0-13.13 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-mantic-linux' to 'verification-done-mantic-linux'. If the problem still exists, change the tag 'verification-needed-mantic-linux' to 'verification-failed-mantic-linux'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.
