8d35d8752b instr_emul: remove vm_gva2gpa
- vm_gva2gpa is same as gva2gpa, so replace it with gva2gpa directly.
- remove dead usage of vm_gva2gpa in emulate_movs.

570aef648a instr_emul: refine decode_instruction with copy_from_gva
use copy_from_gva in vie_init, if copy_from_gva meet -EFAULT, inject #PF.
And for decode_instruction, if return -EFAULT, the caller should keep return
path with successful status.

v2:
- remove vm_restart_instruction when inject #PF

e591315a65 HV:treewide:C99-friendly per_cpu implementation change the per_cpu method
The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.

This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-
es accessible in files.
