[PATCH V5 00/26] mm/mmap: Drop __SXXX/__PXXX macros from across platforms

__SXXX/__PXXX macros is an unnecessary abstraction layer in creating the generic protection_map[] array which is used for vm_get_page_prot(). This abstraction layer can be avoided, if the platforms just define the array protection_map[] for all possible vm_flags access permission combinations and a

[PATCH V5 03/26] powerpc/mm: Move protection_map[] inside the platform

This moves protection_map[] inside the platform and while here, also enable ARCH_HAS_VM_GET_PAGE_PROT on 32 bit and nohash 64 (aka book3e/64) platforms via DECLARE_VM_GET_PAGE_PROT. Cc: Michael Ellerman Cc: Paul Mackerras Cc: Nicholas Piggin Cc: linuxppc-...@lists.ozlabs.org Cc: linux-ker...@vg

[PATCH V5 01/26] mm/mmap: Build protect protection_map[] with __P000

Build protect generic protection_map[] array with __P000, so that it can be moved inside all the platforms one after the other. Otherwise there will be build failures during this process. CONFIG_ARCH_HAS_VM_GET_PAGE_PROT cannot be used for this purpose as only certain platforms enable this config n
