In the hypervisor, VMCS fields include 16-bit fields,
32-bit fields, 64-bit fields and natural-width fields.
In the current implement, there are exec_vmread/exec_vmwrite
used for accessing 32-bit fields, 64-bit field and
natural-width fields. This usage will confue developer.
So there are many type casting for the return value and
parameters vmread/vmwrite operations.
Since exec_vmread/exec_vmwrite and exec_vmread64/exec_vmwrite64
are the same, update current exec_vmread/exec_vmwrite
implement into exec_vmread64/exec_vmwrite64 implement
and add MACRO define for exec_vmread/exec_vmwrite in
head file;
To access 64-bit fields in VMCS, callers use
exec_vmread64/exec_vmwrite64;
Update related variables type for vmread/vmwrite operations;
Update related caller according to VMCS fields size.
Note:Natural-width fields have 64 bits on processors
that support Intel 64 architecture.To access natural-width
fields in VMCS, callers still use exec_vmread/exec_vmwrite,
keep the current implementation.
V1--V2:
This is new part of this patch serial to only
update 64-bit vmread/vmread opertions and related
caller, for netural width fields, still use exec_vmread
or exec_vmwrite.
V2-->V3:
Fix few mistake updations for netural fields in VMCS,
just keep exec_vmread/exec_vmwrite to access them;
Fix few mistake updations for 64-bit fields in VMCS.
V3--V4:
Add "016ll" for 64-bit variable in log function;
Few updates for coding style;
Rename lssd32_idx as tr_sel in VMX module.
V4-->V5:
Use CPU_NATURAL_LAST in the vm_get_register and
vm_set_register to make condition statement more
understandable.
