Date: Thu, 18 Feb 2016 10:35:57 -0800 From: Dave Hansen <dave@...1.net> To: linux-kernel@...r.kernel.org Cc: linux-mm@...ck.org, x86@...nel.org, Dave Hansen <dave@...1.net>, dave.hansen@...ux.intel.com Subject: [PATCH] um, pkeys: give UML an arch_vma_access_permitted() From: Dave Hansen <dave.hansen@...ux.intel.com> UML has a special mmu_context.h and needs updates whenever the generic one is updated. The original pkeys patches missed this. This fixes it up.
