ARM: 6870/1: The mandatory barrier rmb() must be a dsb() in for device accesses Since mandatory barriers may be used (explicitly or implicitly via readl etc.) to ensure the ordering between Device and Normal memory accesses, a DMB is not enough. This patch converts it to a DSB. Cc: Colin Cross <ccross@android.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
