From 416d7214741daba3acd6d328289858390bef37bc Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com> Date: Fri, 10 Feb 2012 09:24:08 -0500 Subject: [PATCH] xen/setup: Remove redundant filtering of PTE masks. commit 7347b4082e55ac4a673f06a0a0ce25c37273c9ec "xen: Allow unprivileged Xen domains to create iomap pages" added a redundant line in the early bootup code to filter out the PTE. That filtering is already done a bit earlier so this extra processing is not required.
