Merge tag 'memblock-v7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mm/memblock
Pull memblock updates from Mike Rapoport:
"Performance improvement:
- Use binary search in memblock_add_range() and
memblock_isolate_range()
Cleanups:
- Several simplifications in memblock and mm_init that remove
redundant code
- After rework of sparsemem buffer preallocation, memmap_alloc() does
not require exact_nid parameter. Remove that parameter, drop now
unused memblock_alloc_exact_nid_raw() and adjust memblock tests
accordingly
memblock test updates:
- add coverage for lowmem allocations
- fix 32-bit build warnings"
* tag 'memblock-v7.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mm/memblock:
memblock: use binary search to locate candidate regions
memblock: drop for_each_memblock_type() and open code its users
memblock: Remove unused memblock_alloc_exact_nid_raw()
memblock tests: Move exact nid tests to memblock_alloc_range_nid()
mm: Remove unused exact_nid parameter from memmap_alloc()
memblock: initialize the region merge end index
tools: use __pa() in virt_to_phys()
memblock tests: zero-extend simulated memory addresses
memblock tests: use physical addresses for region removal
memblock: reject non-page-aligned reserve_mem regions
memblock tests: cover allocations below the low address limit
memblock tests: model the low allocation limit within dummy memory
mm/mm_init: remove zone_absent_pages_in_node()
memblock: remove conditional return with no effect
memblock: simplify reset_all_zones_managed_pages()
