Thanks for the review. You're right, the Fixes tag should be
c309b917cab5 ("cpumask: convert kernel/profile.c").

I went with the minimal fix you suggested since 7c51f7bbf057 touches
two files and adds serialization, which felt heavier for a stable
backport.

Would a v3 with the corrected Fixes tag and a note explaining the
choice over 7c51f7bbf057 work, or would you prefer to just Cc stable
on your commit?
