[PATCH] powerpc/32: Don't populate page tables for block mapped pages except on the 8xx.

2019-08-23 Thread Christophe Leroy
Commit d2f15e0979ee ("powerpc/32: always populate page tables for Abatron BDI.") wrongly sets page tables for any PPC32 for using BDI, and does't update them after init (remove RX on init section, set text and rodata read-only) Only the 8xx requires page tables to be populated for using the BDI.
