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/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 579b9239c1f38665b21e8d0e6ee83ecc96dbd6bb # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- linkstation_defconfig WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] WARNING: unmet direct dependencies detected for PPC_INDIRECT_PCI Depends on [n]: PCI [=n] Selected by [y]: - MPC10X_BRIDGE [=y] # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x578254) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.0.0-rc1-g579b9239c1f3 Created: Fri Feb 1 06:56:43 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2856455 Bytes = 2789.51 KiB = 2.72 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_linkstation_defconfig_powerpc-gcc5 # Build took: 0:00:48.998112
