So there is no point in creating a cache for 4 entries # page tables. # # Also, with HW assistance the entries must be 4k aligned, the 8xx # drops the last 12 bits. Redefine HUGEPD_SHIFT_MASK to mask them out. # # Calculate PTE_T_ORDER using the size of pte_basic_t instead of pte_t. # # In 16k mode, define a specific set_huge_pte_at() function which writes # the pte in a single entry instead of using set_pte_at() which writes # 4 identical entries. Define set_pte_filter() inline otherwise GCC # doesn't inline it anymore because it is now used twice, and that gives # a pretty suboptimal code because of pte_t being a struct of 4 entries. # This function is also used for 512k pages which only require one entry # as well allthough replicating it four times is harmless as 512k pages # entries are spread every 128 bytes in the table. # # Fixes: 22569b881d37 ("powerpc/8xx: Enable 8M hugepage support with HW assistance") # Cc: stable@vger.kernel.org # v5.0+ # Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/e744db1529271d11a3fdcdf641617846907b6ffd.1580997012.git.christophe.leroy@c-s.fr # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld --version # < git log --format=%s --max-count=1 5b82a04d57b60f48dc7f73763941a6542ad1cf16 # < make -s -j 48 ARCH=arm O=/kisskb/build/powerpc-fixes_versatile_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- versatile_defconfig # make -s -j 48 ARCH=arm O=/kisskb/build/powerpc-fixes_versatile_defconfig_arm-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi- /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c: In function 'drm_dp_mst_dsc_aux_for_port': /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5399:9: warning: missing braces around initializer [-Wmissing-braces] struct drm_dp_desc desc = { 0 }; ^ /kisskb/src/drivers/gpu/drm/drm_dp_mst_topology.c:5399:9: warning: (near initialization for 'desc.ident') [-Wmissing-braces] Completed OK # rm -rf /kisskb/build/powerpc-fixes_versatile_defconfig_arm-gcc4.9 # Build took: 0:00:44.608489
