From 9e290a19f21f4d6c305090d3c61fbfad65908188 Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 12 May 2009 12:41:54 -0700 Subject: [PATCH] MIPS: Remove execution hazard barriers for Octeon. The Octeon has no execution hazards, so we can remove them and save an instruction per TLB handler invocation.
