Subject: [Qemu-devel] [PATCH 4/6] ppc: Fix slbia decode
Date: Tue, 07 Jun 2016 11:37:07 +1000	[thread overview]
Message-ID: <1465263427.23889.8.camel@kernel.crashing.org> (raw)

Since at least the 2.05 architecture, the slbia instruction takes an
IH field in the opcode to provide some control on the effect of the
slbia on the ERATs (level-1 TLB).

We can safely ignore it as we always flush the whole qemu TLB but
we should allow the bits in the decode.
