Subject[PATCH 5.10 614/717] powerpc/mm: Fix verification of MMU_FTR_TYPE_44x
Date
From: Christophe Leroy <christophe.leroy@csgroup.eu>

commit 17179aeb9d34cc81e1a4ae3f85e5b12b13a1f8d0 upstream.

MMU_FTR_TYPE_44x cannot be checked by cpu_has_feature()

Use mmu_has_feature() instead

Fixes: 23eb7f560a2a ("powerpc: Convert flush_icache_range & friends to C")
