From 3a72db703cc6965662ff6063befa7d7cf2b49a2e Mon Sep 17 00:00:00 2001 From: Huang Shijie Date: Mon, 18 Apr 2016 09:49:56 +0800 Subject: [PATCH] arm64: mm: remove the redundant code We already re-enable interrupts where necessary in the entry code, so there is no need to do it again in do_page fault. This patch removes the redundant code.
