[PATCH v3 27/29] target/ppc: Use cpu_*_mmuidx_ra instead of MMU_MODE*_SU


From: Richard Henderson
Subject: [PATCH v3 27/29] target/ppc: Use cpu_*_mmuidx_ra instead of MMU_MODE*_SUFFIX
Date: Sun, 29 Dec 2019 10:11:22 +1100

There are only two uses.  Within dcbz_common, the local variable
mmu_idx already contains the epid computation, and we can avoid
repeating it for the store.  Within helper_icbiep, the usage is
trivially expanded using PPC_TLB_EPID_LOAD.
