  "message": "cpus: Don\u0027t kick un-realized cpus.\n\nfollowing a464982499b2f637f6699e3d03e0a9d2e0b5288b, it\u0027s now possible for\nthere to be attempts to take the BQL before CPUs have been realized in\ncases where a machine model inits peripherals before the first CPU.\n\nBQL lock aquisition kicks the first_cpu, leading to a segfault if this\nhappens pre-realize. Guard the CPU kick routine to perform no action for\na CPU that doesn\u0027t exist or doesn\u0027t have a thread yet.\n\nThere was a fix to this with commit\n6b49809c597331803ea941eadda813e5bb4e8fe2, but the check there misses\nthe case where the CPU has been inited and not realized. Strengthen the\ncheck to make sure that the first_cpu has a thread (i.e. it is\nrealized) before allowing the kick.\n\nSigned-off-by: Peter Crosthwaite \u003cpeter.crosthwaite@xilinx.com\u003e\nMessage-Id: \u003c1427107689-6946-1-git-send-email-peter.crosthwaite@xilinx.com\u003e\nSigned-off-by: Paolo Bonzini \u003cpbonzini@redhat.com\u003e\n",
