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/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 03800e0526ee25ed7c843ca1e57b69ac2a5af642 # < make -s -j 48 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- allnoconfig # make -s -j 48 ARCH=x86_64 O=/kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/arch/x86/kernel/apic/io_apic.c: In function 'mp_map_pin_to_irq': /kisskb/src/arch/x86/kernel/apic/io_apic.c:1037:6: warning: 'irq' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:194:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/arch/x86/kernel/e820.c: In function 'e820__setup_pci_gap': /kisskb/src/arch/x86/kernel/e820.c:664:16: warning: 'gapstart' may be used uninitialized in this function [-Wuninitialized] Completed OK # rm -rf /kisskb/build/powerpc-fixes_x86_64-allnoconfig_x86_64-gcc4.6 # Build took: 0:00:24.464150
