[Qemu-ppc] [PULL 42/49] target/ppc: Get rid of POWERPC_MMU_VER() macros


From: David Gibson
Subject: [Qemu-ppc] [PULL 42/49] target/ppc: Get rid of POWERPC_MMU_VER() macros
Date: Fri, 27 Apr 2018 19:21:19 +1000

These macros were introduced to deal with the fact that the mmu_model
field has bit flags mixed in with what's otherwise an enum of various mmu
types.

We've now eliminated all those flags except for one, and that one -
POWERPC_MMU_64 - is already included/compared in the MMU_VER macros.  So,
we can get rid of those macros and just directly compare mmu_model values
in the places it was used.
