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/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 dc398a084d459f065658855454e09f2778f8c5cc # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel-gcc5 CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" Completed OK # rm -rf /kisskb/build/powerpc-fixes_mips-defconfig_mipsel-gcc5 # Build took: 0:02:20.442257
