Iglesias" Date: Thu, 7 Oct 2010 21:20:52 +0200 Subject: [PATCH] cris: Consider the TLB valid bit on writes to the TLB When updating the guest TLB we only need to flush previous mappings from the entry written if the entry was valid. Also fixes a compiler warning reported by Blue Swirl. Signed-off-by: Edgar E.
