3b295bcb32 accel: Rename HVF 'struct hvf_vcpu_state' -> AccelCPUState 
We want all accelerators to share the same opaque pointer in
CPUState.

Rename the 'hvf_vcpu_state' structure as 'AccelCPUState'.

Use the generic 'accel' field of CPUState instead of 'hvf'.

Replace g_malloc0() by g_new0() for readability.

b533450e74 hvf: Introduce hvf vcpu struct 
We will need more than a single field for hvf going forward. To keep
the global vcpu struct uncluttered, let's allocate a special hvf vcpu
struct, similar to how hax does it.

  Count and Logical Processor Count

Bits 15:0 THREAD_COUNT The number of logical processors that are

9fedbbeeee hvf: remove TSC synchronization code because it isn't fully complete 
The existing code in QEMU's HVF support to attempt to synchronize TSC
across multiple cores is not sufficient.  TSC value on other cores
can go backwards.  Until implementation is fixed, remove calls to
hv_vm_sync_tsc().  Pass through TSC to guest OS.
