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 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_tqm8548_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/tqm8548_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_tqm8548_defconfig_powerpc-5.3 CROSS_COMPILE=/opt/cross/kisskb/gcc-5.3.0-nolibc/powerpc64-linux/bin/powerpc64-linux- arch/powerpc/boot/tqm8548.dtb: Warning (pci_bridge): /pcie@e000a000/pcie@0: missing bus-range for PCI bridge arch/powerpc/boot/tqm8548.dtb: Warning (pci_device_bus_num): Failed prerequisite 'pci_bridge' INFO: Uncompressed kernel (size 0x4b80d8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x4a79c0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-4.17.0-rc2-gac61c11 Created: Wed Apr 25 22:30:40 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2403584 Bytes = 2347.25 kB = 2.29 MB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-4.17.0-rc2-gac61c11 Created: Wed Apr 25 22:30:40 2018 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2427457 Bytes = 2370.56 kB = 2.32 MB Load Address: 00500000 Entry Point: 0050020c Completed OK # rm -rf /kisskb/build/powerpc-fixes_85xx_tqm8548_defconfig_powerpc-5.3 # Build took: 0:01:04.310518
