This can cause host DSI, DSLB interrupts # which must test for KVM guest. Restore this and add a comment. # # Fixes: 2284ffea8f0c ("powerpc/64s/exception: Only test KVM in SRR interrupts when PR KVM is supported") # Cc: stable@vger.kernel.org # v5.7+ # Signed-off-by: Nicholas Piggin # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20201117135617.3521127-1-npiggin@gmail.com # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 cd81acc600a9684ea4b4d25a47900d38a3890eab # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc8560_ads_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- cc1: fatal error: opening output file arch/powerpc/boot/dts/fsl/.mpc8560ads.dtb.dts.tmp: No such file or directory compilation terminated. make[2]: *** [scripts/Makefile.lib:326: arch/powerpc/boot/dts/fsl/mpc8560ads.dtb] Error 1 make[2]: *** Waiting for unfinished jobs.... make[1]: *** [arch/powerpc/Makefile:294: zImage] Error 2 make: *** [Makefile:185: __sub-make] Error 2 Command 'make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-fixes_85xx_mpc8560_ads_defconfig_powerpc-gcc4.9 # Build took: 0:00:27.096974
