Merge remote-tracking branch 'remotes/kvm/uq/master' into staging
* remotes/kvm/uq/master: pc: port 92 reset requires a low->high transition cpu: make CPU_INTERRUPT_RESET available on all targets apic: do not accept SIPI on the bootstrap processor target-i386: preserve FPU and MSR state on INIT target-i386: fix set of registers zeroed on reset kvm: forward INIT signals coming from the chipset kvm: reset state from the CPU's reset method target-i386: the x86 CPL is stored in CS.selector - auto update hflags accordingly. target-i386: set eflags prior to calling cpu_x86_load_seg_cache() in seg_helper.c target-i386: set eflags and cr0 prior to calling cpu_x86_load_seg_cache() in smm_helper.c target-i386: set eflags prior to calling svm_load_seg_cache() in svm_helper.c pci-assign: limit # of msix vectors pci-assign: Fix a bug when map MSI-X table memory failed kvm: make one_reg helpers available for everyone target-i386: Remove unused data from local array Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
