[Qemu-ppc] [PULL 2/8] target-ppc: Change default cpu for ppc64le-linux-user

[Alexander Graf]

From: Richard Henderson <address@hidden>

The default, 970fx, doesn't support MSR_LE.  So even though we set LE in
ppc_cpu_reset, it gets cleared again in hreg_store_msr.  Error out if a
user-selected cpu model doesn't support LE.
