Merge tag 'fixes-2021-10-16' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock
Pull memblock fix from Mike Rapoport:
"Fix handling of NOMAP regions with kmemleak.
NOMAP regions don't have linear map entries so an attempt to scan
these areas in kmemleak would fault.
Prevent such faults by excluding NOMAP regions from kmemleak"
