From 7605b3906192a171e651076325b1ed1d5ea57ec9 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 20 Mar 2007 13:56:50 +0000 Subject: [PATCH] [MIPS] Fix pipeline hazard. In the the sequence: ei .. mfc0 $x, $status the mfc0 may not see the SR_IE bit set. This was a deliberate bug in the kernel code because we knew this was a safe thing to do on all R2 silicon so far but new silicon is changing this.
