From cc20cd10179408f3ef98d4452aeef34670eb5cd8 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Tue, 19 Jan 2010 16:42:12 +0100 Subject: [PATCH] ARM: 5885/1: arm: Flush TLB entries in setup_mm_for_reboot() We need to do that if we tinker with the MMU entries. This fixes the occasional bug with kexec where the new fails to uncompress with "crc error". Most likely at least kexec on v6 and v7 need this fix.
