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/ia64-linux/bin/ia64-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux-ld --version # < git log --format=%s --max-count=1 d9101bfa6adc831bda8836c4d774820553c14942 # < make -s -j 40 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- defconfig # make -s -j 40 ARCH=ia64 O=/kisskb/build/powerpc-next_ia64-defconfig_ia64 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/ia64-linux/bin/ia64-linux- <stdin>:1511:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/mm/vmstat.c: In function 'sysctl_vm_numa_stat_handler': /kisskb/src/mm/vmstat.c:90:5: warning: 'oldval' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/mm/hugetlb.c: In function 'alloc_pool_huge_page': /kisskb/src/mm/hugetlb.c:1465:5: warning: 'page' 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/fs/nfsd/nfs4xdr.c: In function 'nfsd4_encode_components_esc': /kisskb/src/fs/nfsd/nfs4xdr.c:2065:9: warning: 'str' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:338:21: note: 'pdeo' was declared here /kisskb/src/kernel/fork.c:771:13: warning: 'task_struct_whitelist' defined but not used [-Wunused-function] /kisskb/src/fs/udf/unicode.c: In function 'udf_name_conv_char': /kisskb/src/fs/udf/unicode.c:132:8: warning: 'c' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/usb/core/devio.c: In function 'async_completed': /kisskb/src/drivers/usb/core/devio.c:613:23: warning: 'errno' may be used uninitialized in this function [-Wuninitialized] No errors detected in 21596 functions.
