From bb48c2fc6429314fa607106ccb901552484c6663 Mon Sep 17 00:00:00 2001 From: David Daney Date: Thu, 1 Aug 2013 13:22:34 -0700 Subject: [PATCH] mips/kvm: Cleanup .push/.pop directives in kvm_locore.S There are: .set push .set noreorder .set noat . . . .set pop Sequences all over the place in this file, but in some places the final ".set pop" is erroneously converted to ".set push", so none of these really do what they appear to. Clean up the whole mess by moving ".set noreorder", ".set noat" to the top, and get rid of everything else. Generated object code is unchanged.
