According to the syntax defined in C99, each struct/union field must have an
identifier. This patch removes unnamed struct/union fields that can be easily
expressed in a C99-compatible way.
Here is a summary of structs/unions removed.
struct vhm_request:
union {
uint32_t type; uint32_t type;
int32_t reserved0[16]; => int32_t reserved0[15];
};
struct vhm_request_buffer:
struct vhm_request_buffer {
union { union vhm_request_buffer {
struct vhm_request ...; => struct vhm_request ...;
int8_t reserved[4096]; int8_t reserved[4096];
} }
}

According to the comments in hypervisor:
" This file includes config header file "bsp_cfg.h" and other
hypervisor used header files.
It should be included in all the source files."

there are data transfer between guest(GPA) & hv(HPA), especially for
hypercall from guest.
guest should make sure these GPAs are address continous, but hv cannot
assure HPAs which mapped to these GPAs are address continous, for example,
after enable hugetlb, a contious GPA range could come from two different
2M pages.
this patch is handling such case by doing gpa page walking during
copy_from_vm & copy_to_vm.

Now one uint64_t type is used to obtain the corresponding descriptor_table
for GDT/IDT. This will cause the stack protect corruption under -O2.
So the descriptor_table struct is added to configure the GDT/IDT of VMCS.
V1->V2: Move the descriptor_table into vmx.h header file
And its type is renamed from dt_addr_t to descriptor_table.

The RFLAGS will be touched in some inline assembly.(exec_vmxon/
RFLAGS_RESTORE). The "cc" constraint should be added. Otherwise
it won't be handled under -O2 option.
And "%%XXX" register should also be added into constraints.
Otherwise it will be optimized incorrectly.
