From: Christophe Leroy Date: Tue, 24 Nov 2020 15:24:54 +0000 (+0000) Subject: powerpc/8xx: DEBUG_PAGEALLOC doesn't require an ITLB miss exception handler X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=613df979da6c032cbe6fa273fb8ca21af022157e;p=linux.git powerpc/8xx: DEBUG_PAGEALLOC doesn't require an ITLB miss exception handler 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.
