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-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < git log --format=%s --max-count=1 ac61c1156623455c46701654abd8c99720bceea1 # < make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+UP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ppc64e_defconfig # Added to kconfig CONFIG_SMP=n # yes \n \| make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+UP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe yes: write error # make -s -j 20 ARCH=powerpc O=/kisskb/build/powerpc-fixes_ppc64e_defconfig+UP_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0xcfcf20) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0xd00000) Image Name: Linux-4.17.0-rc2-gac61c11 Created: Wed Apr 25 21:43:58 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 5578297 Bytes = 5447.56 kB = 5.32 MB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/powerpc-fixes_ppc64e_defconfig+UP_powerpc-5.3 # Build took: 0:02:29.435986
