Subject: [PATCH] powerpc/mm: Fix verification of MMU_FTR_TYPE_44x
Date: Sat, 10 Oct 2020 17:30:59 +0000 (UTC) [thread overview]
Message-ID: <ceede82fadf37f3b8275e61fcf8cf29a3e2ec7fe.1602351011.git.christophe.leroy@csgroup.eu> (raw)
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")
