The fix is simple (it's what I believe we call a "brown paper bag" bug) and I don't think it makes sense to sit on this, particularly as Russell ended up triggering this rather than just somebody noticing a potential problem by inspection. Usually arm64 KVM changes would go via Paolo's tree, but he's on holiday at the moment and the deal is that anything urgent gets shuffled via the arch trees, so here it is. Summary: Fix arm64 KVM issue when injecting an abort into a 32-bit guest, which would lead to an illegal exception return at EL2 and a subsequent host crash" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: KVM: Fix host crash when injecting a fault into a 32bit guest # < /opt/cross/gcc-4.6.3-nolibc/bfin-uclinux/bin/bfin-uclinux-gcc --version # < git log --format=%s --max-count=1 95803812cfb3ece8ee1bb3747611ead48300fca2 # < make -j 8 ARCH=blackfin O=/home/kisskb/slave/build/linus_TCM-BF518_defconfig_bfin CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/bfin-uclinux/bin/bfin-uclinux- TCM-BF518_defconfig # make -j 8 ARCH=blackfin O=/home/kisskb/slave/build/linus_TCM-BF518_defconfig_bfin CROSS_COMPILE=/opt/cross/gcc-4.6.3-nolibc/bfin-uclinux/bin/bfin-uclinux- make[1]: Entering directory '/home/kisskb/slave/build/linus_TCM-BF518_defconfig_bfin' GEN ./Makefile scripts/kconfig/conf --silentoldconfig Kconfig CHK include/config/kernel.release GEN ./Makefile WRAP arch/blackfin/include/generated/asm/auxvec.h WRAP arch/blackfin/include/generated/asm/bitsperlong.h WRAP arch/blackfin/include/generated/asm/bugs.h WRAP arch/blackfin/include/generated/asm/cputime.h WRAP arch/blackfin/include/generated/asm/current.h WRAP arch/blackfin/include/generated/asm/device.h WRAP arch/blackfin/include/generated/asm/div64.h WRAP arch/blackfin/include/generated/asm/errno.h WRAP arch/blackfin/include/generated/asm/emergency-restart.h WRAP arch/blackfin/include/generated/asm/ioctl.h WRAP arch/blackfin/include/generated/asm/fb.h WRAP arch/blackfin/include/generated/asm/hw_irq.h WRAP arch/blackfin/include/generated/asm/futex.h WRAP arch/blackfin/include/generated/asm/ipcbuf.h WRAP arch/blackfin/include/generated/asm/irq_regs.h CHK include/generated/uapi/linux/version.h WRAP arch/blackfin/include/generated/asm/irq_work.h WRAP arch/blackfin/include/generated/asm/kdebug.h WRAP arch/blackfin/include/generated/asm/kmap_types.h WRAP arch/blackfin/include/generated/asm/kvm_para.h WRAP arch/blackfin/include/generated/asm/local.h WRAP arch/blackfin/include/generated/asm/local64.h UPD include/generated/uapi/linux/version.h WRAP arch/blackfin/include/generated/asm/mcs_spinlock.h WRAP arch/blackfin/include/generated/asm/mm-arch-hooks.h WRAP arch/blackfin/include/generated/asm/mman.h WRAP arch/blackfin/include/generated/asm/msgbuf.h WRAP arch/blackfin/include/generated/asm/mutex.h WRAP arch/blackfin/include/generated/asm/param.h WRAP arch/blackfin/include/generated/asm/percpu.h WRAP arch/blackfin/include/generated/asm/pgalloc.h WRAP arch/blackfin/include/generated/asm/preempt.h WRAP arch/blackfin/include/generated/asm/resource.h WRAP arch/blackfin/include/generated/asm/sembuf.h WRAP arch/blackfin/include/generated/asm/serial.h WRAP arch/blackfin/include/generated/asm/setup.h WRAP arch/blackfin/include/generated/asm/shmbuf.h WRAP arch/blackfin/include/generated/asm/shmparam.h WRAP arch/blackfin/include/generated/asm/socket.h WRAP arch/blackfin/include/generated/asm/sockios.h WRAP arch/blackfin/include/generated/asm/statfs.h WRAP arch/blackfin/include/generated/asm/termbits.h WRAP arch/blackfin/include/generated/asm/termios.h WRAP arch/blackfin/include/generated/asm/topology.h WRAP arch/blackfin/include/generated/asm/trace_clock.h WRAP arch/blackfin/include/generated/asm/types.h WRAP arch/blackfin/include/generated/asm/ucontext.h WRAP arch/blackfin/include/generated/asm/unaligned.h WRAP arch/blackfin/include/generated/asm/user.h WRAP arch/blackfin/include/generated/asm/xor.h HOSTCC scripts/basic/bin2c UPD include/config/kernel.release Using /home/kisskb/slave/src as source for kernel CHK include/generated/utsrelease.h UPD include/generated/utsrelease.h CC scripts/mod/empty.o HOSTCC scripts/mod/mk_elfconfig cc1: error: -mcpu=bf518-0.1 has invalid silicon revision cc1: error: unrecognized command line option '-mcpu=bf518-0.1' /home/kisskb/slave/src/scripts/Makefile.build:258: recipe for target 'scripts/mod/empty.o' failed make[3]: *** [scripts/mod/empty.o] Error 1 make[3]: *** Waiting for unfinished jobs....
