Subject: [Qemu-devel] [PATCH] spapr: Clear LPCR_ILE during reset
Date: Thu, 6 Mar 2014 15:06:52 +1100	[thread overview]
Message-ID: <20140306150652.1fc1313b@kryten> (raw)


Since an OS can set LPCR_ILE we must clear it during reset. Otherwise
if we reset into an OS with a different endian we die when we take
the first exception.

This fixes an issue seen on both full emulation and KVM.
