3fdad3c6d1 hv: nested: check prerequisites to enter VMX operation
According to VMXON Instruction Reference, do the following checks in the
virtual hardware environment: vCPU CPL, guest CR0, CR4, revision ID
in VMXON region, etc.

Currently ACRN doesn't support 32-bit L1 hypervisor, and injects an #UD
exception if L1 hypervisor is not running in 64-bit mode.

fc8f07e740 hv: nested: support for VMXON emulation
This patch emulates VMXON instruction. Basically checks some
prerequisites to enable VMX operation on L1 guest (next patch), and
prepares some virtual hardware environment in L0.

Move Cache/TLB arch specific parts into cpu.h
After this change, we should not expose arch specific parts out from mmu.h

688a41c290 hv: mod: do not use explicit arch name when including headers
Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".

In other words, we are adopting the same practice in Linux kernel.
