In those config when we move page # tables we need to make sure we move the deposited page table to the # correct pmd page. Otherwise this can result in crash when we withdraw # of deposited page table because we can find the pmd_huge_pte NULL. # # eg: # # __split_huge_pmd+0x1070/0x1940 # __split_huge_pmd+0xe34/0x1940 (unreliable) # vma_adjust_trans_huge+0x110/0x1c0 # __vma_adjust+0x2b4/0x9b0 # __split_vma+0x1b8/0x280 # __do_munmap+0x13c/0x550 # sys_mremap+0x220/0x7e0 # system_call+0x5c/0x70 # # Fixes: 675d995297d4 ("powerpc/book3s64: Enable split pmd ptlock.") # Cc: stable@vger.kernel.org # v4.18+ # Signed-off-by: Aneesh Kumar K.V <aneesh.kumar@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /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 579b9239c1f38665b21e8d0e6ee83ecc96dbd6bb # < make -s -j 80 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 80 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/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:186:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /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:1034:6: 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:650:16: 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: 0:03:44.716087
