This simply corrects the off by one and should resolve # crashes like below: # # [ 65.179101] page 0x7fff outside node 0 zone DMA [ 0x0 - 0x7fff ] # # Unfortunately in various MM places "max" means a non inclusive end of # range. free_area_init_nodes max_zone_pfn parameter is one case and # MAX_ORDER is another one (unrelated) that comes by memory. # # Reported-by: Zorro Lang <zlang@redhat.com> # Fixes: 25078dc1f74b ("powerpc: use mm zones more sensibly") # Fixes: 9739ab7eda45 ("powerpc: enable a 30-bit ZONE_DMA for 32-bit pmac") # Signed-off-by: Andrea Arcangeli <aarcange@redhat.com> # Reviewed-by: Christoph Hellwig <hch@lst.de> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190625141727.2883-1-aarcange@redhat.com # < /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 03800e0526ee25ed7c843ca1e57b69ac2a5af642 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_TM_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64_defconfig # Added to kconfig CONFIG_PPC_TRANSACTIONAL_MEM=n # yes \n \| make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_TM_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64_defconfig+NO_TM_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/kernel/futex.c: In function 'do_futex': /kisskb/src/kernel/futex.c:1676:17: warning: 'oldval' may be used uninitialized in this function [-Wmaybe-uninitialized] return oldval == cmparg; ^ /kisskb/src/kernel/futex.c:1651:6: note: 'oldval' was declared here int oldval, ret; ^ Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc64_defconfig+NO_TM_powerpc-gcc5 # Build took: 0:01:50.856880
