Hi,

These patches simplify several uses of memblock iterators and hide some of
the memblock implementation details from the rest of the system.

The patches are on top of v5.9-rc1

v3 changes:
* rebase on v5.9-rc1, as the result this required some non-trivial changes
  in patches 10 and 16. I didn't add Baoquan's Reviewed-by to theses
  patches, but I keept Thomas and Miguel
* Add Acked-by from Thomas and Miguel as there were changes in MIPS and
  only trivial changes in .clang-format
* Added Reviewed-by from Baoquan except for the patches 10 and 16
* Fixed misc build errors and warnings reported by kbuild bot
* Updated PowerPC KVM reservation size (patch 2), as per Daniel's comment

v2 changes:
* replace for_each_memblock() with two versions, one for memblock.memory
  and another one for memblock.reserved
* fix overzealous cleanup of powerpc fadamp: keep the traversal over the
  memblocks, but use better suited iterators
* don't remove traversal over memblock.reserved in x86 numa cleanup but
  replace for_each_memblock() with new for_each_reserved_mem_region()
* simplify ramdisk and crash kernel allocations on x86
* drop more redundant and unused code: __next_reserved_mem_region() and
  memblock_mem_size()
* add description of numa initialization fix on arm64 (thanks Jonathan)
* add Acked and Reviewed tags
