Merge branch 'for-5.12' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu

Pull percpu updates from Dennis Zhou:
 "Percpu had a cleanup come in that makes use of the cpu bitmask helpers
  instead of the current iterative approach.

  This clean up then had an adverse interaction when clang's inlining
  sensitivity is changed such that not all sites are inlined resulting
  in modpost being upset with section mismatch due to percpu setup being
  marked __init.

  That was fixed by introducing __flatten to compiler_attributes.h"
