Subject: [PATCH v2 00/17] memblock: seasonal cleaning^w cleanup
Date: Sun,  2 Aug 2020 19:35:44 +0300	[thread overview]
Message-ID: <20200802163601.8189-1-rppt@kernel.org> (raw)

From: Mike Rapoport <rppt@linux.ibm.com>

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 v5.8-rc7 + cherry-pick of "mm/sparse: cleanup the
code surrounding memory_present()" [1] from mmotm tree.

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

  riscv: drop unneeded node initialization
  mircoblaze: drop unneeded NUMA and sparsemem initializations
  memblock: make for_each_memblock_type() iterator private
  memblock: make memblock_debug and related functionality private
  memblock: reduce number of parameters in for_each_mem_range()
  arch, mm: replace for_each_memblock() with for_each_mem_pfn_range()
