For example building a defconfig (which uses 64K pages), changing # the page size to 4K, and rebuilding used to work, because # ARCH_FORCE_MAX_ORDER would be clamped to 12 by the ranges. # # With the ranges removed it creates a kernel that builds but crashes at # boot: # kernel BUG at mm/huge_memory.c:470! # Oops: Exception in kernel mode, sig: 5 [#1] # ... # NIP hugepage_init+0x9c/0x278 # LR do_one_initcall+0x80/0x320 # Call Trace: # do_one_initcall+0x80/0x320 # kernel_init_freeable+0x304/0x3ac # kernel_init+0x30/0x1a0 # ret_from_kernel_user_thread+0x14/0x1c # # The reasoning for removing the ranges was that some of the values were # too large. So take that into account and limit the maximums to 10 which # is the default max, except for the 4K case which uses 12. # # Fixes: 1e8fed873e74 ("powerpc: drop ranges for definition of ARCH_FORCE_MAX_ORDER") # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://msgid.link/20230519113806.370635-1-mpe@ellerman.id.au # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux-ld --version # < git log --format=%s --max-count=1 358e526a1648cdd773ba169da5867874ae2408e3 # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux- defconfig # Added to kconfig CONFIG_DEBUG_INFO_BTF=n # Added to kconfig # < make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux- help # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux- olddefconfig .config:3670:warning: override: reassigning to symbol DEBUG_INFO_BTF # make -s -j 160 ARCH=s390 O=/kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.5.0-nolibc/s390-linux/bin/s390-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_s390-defconfig_s390x-gcc8 # Build took: 0:04:57.666679
