Nothing logged to disk. # # He bisected to my 6.6 a349d72fd9ef ("mm/pgtable: add rcu_read_lock() and # rcu_read_unlock()s"): but the one to blame is my 6.5 commit to fix the # espfix "bad pmd" warnings when booting x86_64 with CONFIG_EFI_PGT_DUMP=y. # # Gaah, that added an "addr >= TASK_SIZE" check to avoid pte_offset_map(), # but failed to add the equivalent check when choosing to pte_unmap(). # # It's not a problem on 6.5 (for different reasons, it's harmless on both # 64-bit and 32-bit), but becomes a bootstopper on 6.6 with the unbalanced # rcu_read_unlock() - RCU has a WARN_ON_ONCE for that, but it would have # scrolled off Mikhail's console too quickly. # # Reported-by: Mikhail Gavrilov <mikhail.v.gavrilov@gmail.com> # Closes: https://lore.kernel.org/linux-mm/CABXGCsNi8Tiv5zUPNXr6UJw6qV1VdaBEfGqEAMkkXE3QPvZuAQ@mail.gmail.com/ # Fixes: 8b1cb4a2e819 ("mm/pagewalk: fix EFI_PGT_DUMP of espfix area") # Fixes: a349d72fd9ef ("mm/pgtable: add rcu_read_lock() and rcu_read_unlock()s") # Signed-off-by: Hugh Dickins <hughd@google.com> # Tested-by: Mikhail Gavrilov <mikhail.v.gavrilov@gmail.com> # Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux-ld --version # < git log --format=%s --max-count=1 ee40d543e97d23d3392d8fb1ec9972eb4e9c7611 # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- allyesconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- help # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- olddefconfig # make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- Generating include/generated/machtypes.h <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S: Assembler messages: /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:85: Warning: overflow in branch to __restore_all; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:357: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/arch/sh/kernel/cpu/sh2/../../entry-common.S:360: Warning: overflow in branch to syscall_exit_work; converted into longer instruction sequence /kisskb/src/drivers/mfd/cs42l43.c:1106:12: error: 'cs42l43_resume' defined but not used [-Werror=unused-function] 1106 | static int cs42l43_resume(struct device *dev) | ^~~~~~~~~~~~~~ /kisskb/src/drivers/mfd/cs42l43.c:1076:12: error: 'cs42l43_suspend' defined but not used [-Werror=unused-function] 1076 | static int cs42l43_suspend(struct device *dev) | ^~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make[5]: *** [/kisskb/src/scripts/Makefile.build:243: drivers/mfd/cs42l43.o] Error 1 make[5]: *** Waiting for unfinished jobs.... make[4]: *** [/kisskb/src/scripts/Makefile.build:480: drivers/mfd] Error 2 make[4]: *** Waiting for unfinished jobs.... make[3]: *** [/kisskb/src/scripts/Makefile.build:480: drivers] Error 2 make[3]: *** Waiting for unfinished jobs.... make[2]: *** [/kisskb/src/Makefile:2029: .] Error 2 make[1]: *** [/kisskb/src/Makefile:234: __sub-make] Error 2 make: *** [Makefile:234: __sub-make] Error 2 Command 'make -s -j 24 ARCH=sh O=/kisskb/build/linus_allyesconfig_sh4-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sh4-linux/bin/sh4-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allyesconfig_sh4-gcc13 # Build took: 0:11:36.969456
