2ea3b49858 HV: refine copy_from_vm/copy_to_vm
If the target is an array, then only the first element
will be copied.
So replace structure assignment with memcpy_s().

121d14a616 rename 'req_buf' field in 'struct vm_sw_info'
- rename it to 'io_shared_page' to keep consistent
   with ACRN HDL foils.

 - update related code that reference this data structure.

c0d4b90415 ptdev: change remapping entry from virtual to physical based
currently, pass-thru devices are managed by per-vm's remapping entries
which is virtual based:
- MSI entry is identified by virt_bdf+msix_index
- INTx entry is identified by virt_pin+vpin_src
it works but it's not a good design for physical resource management, for
example a physical IOAPIC pin could belong to different vm's INTx entries,
the Device Model then must make sure there is no resource conflict from
application's level.

This patch change the design from virtual to physical based:
- MSI entry is identified by phys_bdf+msix_index
- INTx entry is identified by phys_pin
The physical resource is directly managed in hypervisor, a miss adding
entry will be found by hypervisor and return error message with failure.

c3374a519a HV: code cleanup for cpu state
Split pm.c from cpu_state_tbl.c to put guest power management related
functions, keep cpu_state_tbl.c to store host cpu state table and
related functions.

9b37e1464c add IO requrest 'req_buf' check before reference
This address maybe invalid if a hostile address was set
in hypercall 'HC_SET_IOREQ_BUFFER'.it should be validated
before using.

Update:
  -- save HVA to guest OS's request buffer in hyperviosr
  -- change type of 'req_buf' from 'uint64_t' to 'void *'
  -- remove HPA to HVA translation code when using this addr.
  -- use error number instead of -1 when return error cases.

a0b7fb81b4 Add range check for 'vm0_gpa' before creating EPT
Input('vm0_gpa') should be validated when handling
hypercall 'HC_VM_SET_MEMMAP to create EPT for UOS
in 'hcall_set_vm_memmap()' function.
at least 'hpa' range (from 'vm0_gpa') can't overlap
hypervisor memory region.

1d0d4d3185 HV: add hypercall interface of get vcpu state data
We can use this interface for VHM to pass per-cpu power state data
to guest per its request.

For now the vcpu power state is per-vm, this could be changed if
per-cpu power state support is required in the future.

4542d3775d hypercall: Fix compile error caused by missing memcpy function
Assignment of structures are implemented using memcpy which is not
available in the hypervisor. This patch convert such assignment to an
explicit memcpy_s() call.

1fd07ba349 trusty: Simulate Secure Monitor Call(SMC) by Hypercall
For ARM, The SMC instruction is used to generate a synchronous
exception that is handled by Secure Monitor code running in EL3.
In the ARM architecture, synchronous control is transferred between
the normal Non-secure state and the Secure state through Secure
Monitor Call exceptions. SMC exceptions are generated by the SMC
instruction, and handled by the Secure Monitor.The operation of
the Secure Monitor is determined by the parameters that are passed
in through registers.

For ACRN, Hypervisor will simulate SMC by hypercall to switch vCPU
State between Normal World and Secure World.
There are 4 registers(RDI, RSI, RDX, RBX) reserved for paramters
passing between Normal World and Secure World.
