[PATCH v1 1/6] powerpc/8xx: DEBUG_PAGEALLOC doesn't require an ITLB miss exception handler

2020-11-24 Thread Christophe Leroy
Since commit e611939fc8ec ("powerpc/mm: Ensure change_page_attr() doesn't invalidate pinned TLBs"), pinned TLBs are not anymore invalidated by __kernel_map_pages() when CONFIG_DEBUG_PAGEALLOC is selected. Remove the dependency on CONFIG_DEBUG_PAGEALLOC. Signed-off-by: Christophe Leroy ---
