[SRU][N][PATCH v3 0/4] Fix time-out issues on powerpc when running ubuntu_kernel_selftests

[Zixing Liu]

BugLink: https://bugs.launchpad.net/bugs/2141536

SRU Justification:

[Impact]

Some PowerPC tests from Ubuntu_kernel_selftests keep timing out.

[Fix]

Backport upstream patchset:
https://lore.kernel.org/all/20241106130453.1741013-1-mpe@ellerman.id.au

[Test Plan]

Running all the kernel selftests for the PowerPC platform to see if they still
times out.

[Where problems could occur]

The patches may introduce new test failures due to improved error detection
that may reveal previously passing tests now fail.

[Other Info]
