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-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 ee40d543e97d23d3392d8fb1ec9972eb4e9c7611 # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allmodconfig_sparc64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_HAVE_FTRACE_MCOUNT_RECORD=n # Added to kconfig CONFIG_SAMPLES=n # Added to kconfig CONFIG_MODULE_SIG=n # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allmodconfig_sparc64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allmodconfig_sparc64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allmodconfig_sparc64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux- <stdin>:1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: drivers/pci/of_property.o: in function `of_pci_prop_intr_map': of_property.c:(.text+0xc4): undefined reference to `of_irq_parse_raw' make[3]: * [/kisskb/src/scripts/Makefile.vmlinux:36: vmlinux] Error 1 make[2]: * [/kisskb/src/Makefile:1251: vmlinux] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:234: __sub-make] Error 2 make: *** [Makefile:234: __sub-make] Error 2 Command 'make -s -j 160 ARCH=sparc64 O=/kisskb/build/linus_allmodconfig_sparc64-gcc11 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-11.3.0-nolibc/sparc64-linux/bin/sparc64-linux- ' returned non-zero exit status 2. # rm -rf /kisskb/build/linus_allmodconfig_sparc64-gcc11 # Build took: 0:10:54.510706
