hugetlb: introduce generic version of huge_ptep_get

2018-10-26T23:26:34+00:00

ia64, mips, parisc, powerpc, sh, sparc, x86 architectures use the same
version of huge_ptep_get, so move this generic implementation into
asm-generic/hugetlb.h.

mm/hugetlb: remove arch_prepare/release_hugepage from arch headers

2015-06-26T00:00:35+00:00

Nobody used these hooks so they were removed from common code, and can now
be removed from the architectures.

mm/hugetlb: reduce arch dependent code about hugetlb_prefault_arch_hook

2015-06-25T00:49:41+00:00

Currently we have many duplicates in definitions of
hugetlb_prefault_arch_hook.  In all architectures this function is empty.

ARM: mm: HugeTLB support for LPAE systems.

2013-06-04T15:52:37+00:00

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).

[steve.capper@linaro.org: 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].
