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. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
