[PATCH 1/6] mm: introduce an additional vma bit for powerpc pkey

2017-09-15 Thread Ram Pai
Currently only 4bits are allocated in the vma flags to hold 16 keys. This is sufficient for x86. PowerPC supports 32 keys, which needs 5bits. This patch allocates an additional bit. Signed-off-by: Ram Pai --- fs/proc/task_mmu.c |6 -- include/linux/mm.h | 16
