To make it safe against a THP # split and/or collapse, we disable interrupts around the lockless page # table walk. However we need to keep interrupts disabled as long as we # use the page table entry pointer that is returned. # # Fix addr_to_pfn() to do that. # # Fixes: ba41e1e1ccb9 ("powerpc/mce: Hookup derror (load/store) UE errors") # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # [mpe: Rearrange code slightly and tweak change log wording] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20190918145328.28602-1-aneesh.kumar@linux.ibm.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 d9101bfa6adc831bda8836c4d774820553c14942 # < make -s -j 32 ARCH=x86_64 O=/kisskb/build/powerpc-next_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 32 ARCH=x86_64 O=/kisskb/build/powerpc-next_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/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] /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] Completed OK # rm -rf /kisskb/build/powerpc-next_x86_64-allnoconfig_x86_64-gcc4.6 # Build took: 0:00:21.857836
