For # example panic() will call smp_send_stop() early on which calls # stop_this_cpu() on other CPUs, then later in the reboot path, # pnv_restart() will call smp_send_stop() again, which hangs. # # Fix this by adding a special case to the stop_this_cpu() handler to # decrement the busy count, because it will never return. # # Now that the NMI/non-NMI versions of stop_this_cpu() are different, # split them out into separate functions rather than doing #ifdef tricks # to share the body between the two functions. # # Fixes: 6bed3237624e3 ("powerpc: use NMI IPI for smp_send_stop") # Reported-by: Abdul Haleem <abdhalee@linux.vnet.ibm.com> # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # [mpe: Split out the functions, tweak change log a bit] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # < /opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux-gcc --version # < git log --format=%s --max-count=1 ac61c1156623455c46701654abd8c99720bceea1 # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64le_defconfig+NO_KVM_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- ppc64le_defconfig # Added to kconfig CONFIG_KVM_BOOK3S_64=n # Added to kconfig CONFIG_KVM=n # yes \n \| make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64le_defconfig+NO_KVM_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64le_defconfig+NO_KVM_ppc64le CROSS_COMPILE=/opt/cross/kisskb/gcc-5.2.0-nolibc/powerpc64le-linux/bin/powerpc64le-linux- WARNING: modpost: Found 3 section mismatch(es).
