The warning could be # removed, but it's potentially useful. # # All other NMIs and soft-NMIs return using EXCEPTION_RESTORE_REGS, so # this makes perf interrupts consistent with that and seems like the best # fix. # # Signed-off-by: Nicholas Piggin <npiggin@gmail.com> # [mpe: Squash in fixups from Nick] # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20221006140413.126443-3-npiggin@gmail.com # < /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 dc398a084d459f065658855454e09f2778f8c5cc # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc7448_hpc2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- mpc7448_hpc2_defconfig # < make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc7448_hpc2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc7448_hpc2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 24 ARCH=powerpc O=/kisskb/build/powerpc-fixes_mpc7448_hpc2_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_mpc7448_hpc2_defconfig_powerpc-gcc5 # Build took: 0:01:04.762448
