It may happen, for example when querying a PHB interrupt # while the PHB is in an error state. # # In that case, we should consider the interrupt to be invalid when # checking its state in the irq_get_irqchip_state() handler. # # Fixes: da15c03b047d ("powerpc/xive: Implement get_irqchip_state method for XIVE to fix shutdown race") # Cc: stable@vger.kernel.org # v5.4+ # Signed-off-by: Frederic Barrat # [clg: wrote a commit log, introduced XIVE_ESB_INVALID ] # Signed-off-by: Cédric Le Goater # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20200113130118.27969-1-clg@kaod.org # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 15ae5119c2dd05eb3f4de0c8f10ede7c95e4017b # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_bamboo_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 44x/bamboo_defconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-fixes_44x_bamboo_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- INFO: Uncompressed kernel (size 0x487aa8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) INFO: Uncompressed kernel (size 0x487aa8) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x500000) Image Name: Linux-5.5.0-rc3-g15ae5119c2dd Created: Wed Jan 15 07:20:35 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2324811 Bytes = 2270.32 KiB = 2.22 MiB Load Address: 00500000 Entry Point: 005001b8 Completed OK # rm -rf /kisskb/build/powerpc-fixes_44x_bamboo_defconfig_powerpc-gcc5 # Build took: 0:00:36.788205
