84d320d49c HV:treewide:Fix type conversion in VMX, timer and MTTR module
There are some integer type conversions in the VMX, timer
and MTTR module detected by static analysis tool.

Update related integer type in VMX, timer and MTTR
module.
Add related constant value with 'U/UL' suffix.

V1-->V2:
        Resolve few rebase conflicts.
V2-->V3:
        Add 'h' for uint16_t argument in log function;
	Update the type of temp variable 'type' as uint8_t
	in MTTR module to reduce type conversion.

d0df39cbb5 hv: emulate CR0.CD and CR0.NW
This patch makes use of IA32_PAT MSR to emulate cache disabled behaviour

When the guest is requesting to set CR0.CD:
 - Keep guest's CR0.CD and CR0.NW bits unchanged
 - Write IA32_PAT MSR with all-UC entries to change the effective memory
   type for all GPA to UC for the guest VCPU
 - It depends on trapping wrmsr to IA32_PAT to prevent any entry in
   IA32_PAT being changed to non UC type by the guest

When the guest is requesting to clear CR0.CD:
 - restore the content of guest's IA32_PAT MSR

6801d826e2 hv: intercept IA32_PAT MSR
Preparing for emulating guest's CR0.CD and CR0.NW bits:
 - Intercept both rdmsr and wrmsr for IA32_PAT
 - Track guest's IA32_PAT MSR with vcpu.arch_vcpu.contexts.ia32_pat
