2020-06-03mm/hugetlb: define a generic fallback for arch_clear_hugepage_flags()Anshuman Khandual1-0/+1
There are multiple similar definitions for arch_clear_hugepage_flags() on various platforms. Lets just add it's generic fallback definition for platforms that do not override. This help reduce code duplication.

2013-06-04ARM: mm: HugeTLB support for LPAE systems.Catalin Marinas1-0/+84
This patch adds support for hugetlbfs based on the x86 implementation. It allows mapping of 2MB sections (see Documentation/vm/hugetlbpage.txt for usage). The 64K pages configuration is not supported (section size is 512MB in this case). Signed-off-by: Catalin Marinas <[email protected]> [[email protected]: symbolic constants replace numbers in places. Split up into multiple files, to simplify future non-LPAE support, removed huge_pmd_share code, as this is very rarely executed, Added PROT_NONE support].
