mm: generalize ARCH_ENABLE_MEMORY_[HOTPLUG|HOTREMOVE]

2021-05-05T18:27:25+00:00

ARCH_ENABLE_MEMORY_[HOTPLUG|HOTREMOVE] configs have duplicate
definitions on platforms that subscribe them.  Instead, just make them
generic options which can be selected on applicable platforms.

hugetlb: pass vma into huge_pte_alloc() and huge_pmd_share()

2021-05-05T18:27:20+00:00

Patch series "hugetlb: Disable huge pmd unshare for uffd-wp", v4.

This series tries to disable huge pmd unshare of hugetlbfs backed memory
for uffd-wp.  Although uffd-wp of hugetlbfs is still during rfc stage,
the idea of this series may be needed for multiple tasks (Axel's uffd
minor fault series, and Mike's soft dirty series), so I picked it out
from the larger series.

This patch (of 4):

It is a preparation work to be able to behave differently in the per
architecture huge_pte_alloc() according to different VMA attributes.

Pass it deeper into huge_pmd_share() so that we can avoid the find_vma() call.

mm: move mem_init_print_info() into mm_init()

2021-04-30T18:20:42+00:00

mem_init_print_info() is called in mem_init() on each architecture, and
pass NULL argument, so using void argument and move it into mm_init().

mm: move page_mapping_file to pagemap.h

2021-04-30T18:20:37+00:00

page_mapping_file() is only used by some architectures, and then it
is usually only used in one place.  Make it a static inline function
so other architectures don't have to carry this dead code.

arch, mm: replace for_each_memblock() with for_each_mem_pfn_range()

2020-10-14T01:38:35+00:00

There are several occurrences of the following pattern:

	for_each_memblock(memory, reg) {
		start_pfn = memblock_region_memory_base_pfn(reg);
		end_pfn = memblock_region_memory_end_pfn(reg);

		/* do something with start_pfn and end_pfn */
	}

Rather than iterate over all memblock.memory regions and each time query
for their start and end PFNs, use for_each_mem_pfn_range() iterator to get
simpler and clearer code.
