Merge remote-tracking branch 'remotes/kvm/tags/for-upstream' into staging
Mostly bugfixes + Alexey's interface-based implementation of the NMI monitor command. # gpg: Signature made Thu 28 Aug 2014 15:07:22 BST using RSA key ID 9B4D86F2 # gpg: Good signature from "Paolo Bonzini <pbonzini@redhat.com>" # gpg: aka "Paolo Bonzini <bonzini@gnu.org>" * remotes/kvm/tags/for-upstream: mc146818rtc: reinitialize irq_reinject_on_ack_count on reset target-i386: Add "tsc_adjust" CPU feature name target-i386: Add "mpx" CPU feature name vl: process -object after other backend options checkpatch.pl: adjust typedef definition to QEMU coding style x86: Clear MTRRs on vCPU reset x86: kvm: Add MTRR support for kvm_get|put_msrs() x86: Use common variable range MTRR counts target-i386: Don't forbid NX bit on PAE PDEs and PTEs spapr: Add support for new NMI interface s390x: Migrate to new NMI interface s390x: Convert QEMUMachine to MachineClass cpus: Define callback for QEMU "nmi" command kvm: run cpu state synchronization on target vcpu thread Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
