X-Git-Tag: upstream/snapshot3+hdmi~8087^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=416d7214741daba3acd6d328289858390bef37bc;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git 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.
