From 07fec1c2e75ef2f55d7a211414b0d63e185e84f0 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Thu, 17 Apr 2014 12:53:13 +0200 Subject: [PATCH] KVM: PPC: E500: Ignore L1CSR1_ICFI,ICLFR The L1 instruction cache control register contains bits that indicate that we're still handling a request. Mask those out when we set the SPR so that a read doesn't assume we're still doing something.
