From: Catalin Marinas Date: Wed, 24 Apr 2013 13:47:02 +0000 (+0100) Subject: arm64: Execute DSB during thread switching for TLB/cache maintenance X-Git-Tag: omap-for-v3.10/dt-fixes-for-merge-window~100^2~7 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5108c67c376b3ee59cc7fbe46eaba481eb3419aa;p=pandora-kernel.git arm64: Execute DSB during thread switching for TLB/cache maintenance The DSB following TLB or cache maintenance ops must be run on the same CPU. With kernel preemption enabled or for user-space cache maintenance this may not be the case. This patch adds an explicit DSB in the __switch_to() function.
