Merge tag 'memblock-v5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock

Pull memblock updates from Mike Rapoport:
 "memblock debug enhancements.

  Improve tracking of early memory allocations when memblock debug is
  enabled:

   - Add memblock_dbg() to memblock_phys_alloc_range() to get details
     about its usage

   - Make memblock allocator wrappers actually inline to track their
     callers in memblock debug messages"

* tag 'memblock-v5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock:
  mm: memblock: drop __init from memblock functions to make it inline
  mm: memblock: add more debug logs
