Patch to access the debug registers (IACx/DACx) using ONE_REG api
was sent earlier. But that missed the respective documentation.

I'm not sure if it was 3.4.0, 3.4.3, or 3.4.4. Since May 17, I have been
building all my kernels (including those) with this patch applied.

Instead of populating the the entire register file, read in registers
as they are accessed, and write back only the modified ones. This
saves a VMREAD and VMWRITE on Intel (for rsp, since it is not usually
used during emulation), and a two 128-byte copies for the registers.

If !CONFIG_KVM_GUEST, kvm_smp_prepare_boot_cpu() is not defined. So,
kvm_register_clock("primary cpu clock") in kvm_smp_prepare_boot_cpu()
is not called.
The detail of problem is hv_clock percpu usage. hv_clock is percpu
variable, but kvmclock_init() is called _before_ initializing percpu

Move the init of the irqchip_inject_ioctl field of KVMState out of
kvm_irqchip_create() and into kvm_init(), so that kvm_set_irq()
can be used even when no irqchip is created (for architectures
that support async interrupt notification even without an in
kernel irqchip).
