[Qemu-ppc] [RFC PATCH] booke206: fix MAS update on tlb miss


From: KONRAD Frederic
Subject: [Qemu-ppc] [RFC PATCH] booke206: fix MAS update on tlb miss
Date: Tue, 1 Aug 2017 10:44:57 +0200

When a tlb instruction miss happen, rw is set to 0 at the bottom
of cpu_ppc_handle_mmu_fault which cause the MAS update function to miss
the SAS and TS bit in MAS6, MAS1 in booke206_update_mas_tlb_miss.

Just calling booke206_update_mas_tlb_miss with rw = 2 solve the issue.
