Intel's new PKU extension introduces a bit of the page fault error code that must be dynamically computed after the PTE lookup (unlike I/D, U/S and W/R). To ease this, these two patches make permission_fault return the page fault error code. Right now it only adds the P bit to the input parameter "pfec", but PKU can change that.
