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/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-gcc --version # < /opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux-ld --version # < git log --format=%s --max-count=1 5b82a04d57b60f48dc7f73763941a6542ad1cf16 # < make -s -j 32 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- mmu_defconfig # make -s -j 32 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- /kisskb/src/kernel/debug/kdb/kdb_main.c: In function 'kdb_rd': /kisskb/src/kernel/debug/kdb/kdb_main.c:1857:11: error: 'dbg_reg_def' undeclared (first use in this function) rsize = dbg_reg_def[i].size * 2; ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1857:11: note: each undeclared identifier is reported only once for each function it appears in /kisskb/src/kernel/debug/kdb/kdb_main.c:1868:12: error: implicit declaration of function 'dbg_get_reg' [-Werror=implicit-function-declaration] rname = dbg_get_reg(i, &reg8, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1868:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg8, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1874:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg16, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1880:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg32, kdb_current_regs); ^ /kisskb/src/kernel/debug/kdb/kdb_main.c:1886:10: warning: assignment makes pointer from integer without a cast [-Wint-conversion] rname = dbg_get_reg(i, &reg64, kdb_current_regs); ^ cc1: some warnings being treated as errors make[4]: * [/kisskb/src/scripts/Makefile.build:265: kernel/debug/kdb/kdb_main.o] Error 1 make[4]: * Waiting for unfinished jobs.... make[3]: * [/kisskb/src/scripts/Makefile.build:503: kernel/debug/kdb] Error 2 make[3]: * Waiting for unfinished jobs.... make[2]: * [/kisskb/src/scripts/Makefile.build:503: kernel/debug] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1681: kernel] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 32 ARCH=microblaze O=/kisskb/build/powerpc-fixes_mmu_defconfig_microblaze CROSS_COMPILE=/opt/cross/kisskb/br-microblaze-full-2016.08-613-ge98b4dd/bin/microblazeel-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_mmu_defconfig_microblaze # Build took: 0:00:45.974569
