Subject[PATCH v2 00/17] memblock: seasonal cleaning^w cleanup
Date
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

Mike Rapoport (17):
KVM: PPC: Book3S HV: simplify kvm_cma_reserve()
dma-contiguous: simplify cma_early_percent_memory()
arm, xtensa: simplify initialization of high memory pages
arm64: numa: simplify dummy_numa_init()
h8300, nds32, openrisc: simplify detection of memory extents
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()
arch, drivers: replace for_each_membock() with for_each_mem_range()
x86/setup: simplify initrd relocation and reservation
x86/setup: simplify reserve_crashkernel()
memblock: remove unused memblock_mem_size()
memblock: implement for_each_reserved_mem_region() using __next_mem_region()
memblock: use separate iterators for memory and reserved regions
