Missing upstream commits for LP: #2102181

[Mehmet Basaran]

When applying upstream stable patchset (v6.6.67, v6.12.6) we forgot to include:

acea3779b2aa libperf cpumap: Add any, empty and min helpers

As a result kernel fails to compile.

I am thinking we should include the following 2 commits from upstream as a fix:
dcd45b376d0a libperf cpumap: Ensure empty cpumap is NULL from alloc
b6b4a62d8525 libperf cpumap: Add any, empty and min helpers

Failure:

This bug is awaiting verification that the linux/6.8.0-60.63 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-noble-linux' to 'verification-done-noble-linux'. If the problem still exists, change the tag 'verification-needed-noble-linux' to 'verification-failed-noble-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.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
