Merge branch 'for-5.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu
Pull percpu fix and cleanup from Dennis Zhou:
"A fix for a Wshadow warning in the asm-generic percpu macros came in
and then I tacked on the removal of flexible array initializers in the
percpu allocator"
* 'for-5.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu:
percpu: convert flexible array initializers to use struct_size()
asm-generic: percpu: avoid Wshadow warning
