[RFC v4 02/17] mm: ability to disable execute permission on a key at creation

2017-06-27 Thread Ram Pai
Currently sys_pkey_create() provides the ability to disable read and write permission on the key, at creation. powerpc has the hardware support to disable execute on a pkey as well.This patch enhances the interface to let disable execute at key creation time. x86 does not allow this.
