[Qemu-devel] [PATCH 7/9] ppc: Fix slbia decode

From: Benjamin Herrenschmidt
Subject: [Qemu-devel] [PATCH 7/9] ppc: Fix slbia decode
Date: Tue, 7 Jun 2016 12:50:26 +1000

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.
