Merge remote-tracking branch 'remotes/kvm/uq/master' into staging
* remotes/kvm/uq/master:
kvm: Fix eax for cpuid leaf 0x40000000
kvmclock: Ensure proper env->tsc value for kvmclock_current_nsec calculation
kvm: Enable -cpu option to hide KVM
kvm: Ensure negative return value on kvm_init() error handling path
target-i386: set CC_OP to CC_OP_EFLAGS in cpu_load_eflags
target-i386: get CPL from SS.DPL
target-i386: rework CPL checks during task switch, preparing for next patch
target-i386: fix segment flags for SMM and VM86 mode
target-i386: Fix vm86 mode regression introduced in fd460606fd6f.
kvm_stat: allow choosing between tracepoints and old stats
kvmclock: Ensure time in migration never goes backward
