This is not the case for BAT 4 above. # # Fix kasan_init_region() by using block_size() function that is in # book3s32/mmu.c. To be able to reuse it here, make it non static and # change its name to bat_block_size() in order to avoid name conflict # with block_size() defined in <linux/blkdev.h> # # Also reuse find_free_bat() to avoid an error message from setbat() # when no BAT is available. # # And allocate memory outside of linear memory mapping to avoid # wasting that precious space. # # With this change we get correct alignment for BATs and KASAN shadow # memory is allocated outside the linear memory space. # # ---[ Data Block Address Translation ]--- # 0: 0xc0000000-0xcfffffff 0x00000000 256M Kernel rw # 1: 0xd0000000-0xdfffffff 0x10000000 256M Kernel rw # 2: 0xe0000000-0xefffffff 0x20000000 256M Kernel rw # 3: 0xf8000000-0xfbffffff 0x7c000000 64M Kernel rw # 4: 0xfc000000-0xfdffffff 0x7a000000 32M Kernel rw # # Fixes: 7974c4732642 ("powerpc/32s: Implement dedicated kasan_init_region()") # Cc: stable@vger.kernel.org # Reported-by: Maxime Bizon <mbizon@freebox.fr> # Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> # Tested-by: Maxime Bizon <mbizon@freebox.fr> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/7a50ef902494d1325227d47d33dada01e52e5518.1641818726.git.christophe.leroy@csgroup.eu # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 d37823c3528e5e0705fc7746bcbc2afffb619259 # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- amigaone_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_amigaone_defconfig_powerpc-gcc5 # Build took: 0:01:08.615083
