20c80ea72a HV: bug fix on emulating msi message from guest
Current code has a mistake associating destination with
redirectionhint. So just use the destination mode to work out
destination mode.

When injecting the msi interrupt to vcpu in hypervisor layer,
current code ingnores the redirection hint(RH) bit of msi address
message from guest, and just use the destination mode and
destination ID. So correctly before injecting, check the RH bit,
if set, choose the vcpu that has lowest priority to inject msi.

a257f2fadc HV: Fixes index out of bounds for addressing irq.
NR_MAX_IRQS is defined as 272 and IRQ_INVALID as 273 which implies
that 272 is a valid irq number. In this case, an illegal access can
occur at run time when irq_desc_array[] or irq_count[] is accessed
with index 272. This fix stops the illegal access by renaming
NR_MAX_IRQS to NR_IRQS and then places proper conditions for range
checks. If the index is >= NR_IRQS, then index is invalid otherwise
its considered valid for accessing irq arrays. IRQ_INVALID definition
is also changed to 0xffffffffU to indicate maximum unsigned value.

f912953539 HV:treewide:Update exec_vmread/exec_vmwrite and exec_vmread64/exec_vmwrite64
In the hypervisor, VMCS fields include 16-bit 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:

69ebf4c6e6 HV: vioapic: cleaning up integral-type-related violations
This patch cleans up the integral-type-related violations after the access
pattern to RTEs is unified. Major changes include:

    1. vioapic_mmio_read(), vioapic_mmio_write() and vioapic_mmio_rw() assumes
       the size of the register to be accessed is always 4, which is checked in
       vioapic_mmio_access_handler(). Thus they no longer takes the unused
       ''size'' parameter.

    2. Typical integral-type-related violation fixes including 'U' suffixes,
       type of local variables, conversion specification in format strings, etc.

v1 -> v2:

    * Drop duplicated definitions to IOAPIC register offsets.
    * Drop the ''size'' parameter of vioapic_mmio_[read|write] and
      vioapic_mmio_rw since vioapic_mmio_access_handler() ensures that size is
      always 4.

a1069a5117 HV: ioapic: unify the access pattern to RTEs
There are two different ways the current implementation adopts to access ioapic
RTEs:

    1. As two 32-bit registers (typically named ''low'' and ''high''), or

    2. As one 64-bit register (typically named ''rte'').

Two issues arise due to the mixed use of these two patterns.

    1. Additional conversions are introduced. As an example, ioapic_get_rte()
       merges two RTE fragments into a uint64_t, while some callers break it
       back to ''low'' and ''high'' again.

    2. It is tricky to choose the proper width of IOAPIC_RTE_xxx constants. SOS
       boot failure is seen when they are 32-bit due to the following code:

           /* reg is uint64_t */
           vioapic->rtbl[pin].reg &= ~IOAPIC_RTE_REM_IRR;

       while making them 64-bit leads to implicit narrowing when the RTEs are accessed
       in the low & high pattern.

This patch defines a union ''ioapic_rte'' and unifies the access pattern
to IOAPIC and vIOAPIC RTEs.

v1 -> v2:

    * Instead of two 32-bit ''low'' and ''high'', define a union that allows
      either 32-bit or 64-bit accesses to RTEs.

1d628c640c hv:fix MISRA-C return value violation
1) Change these 5 APIs to void type:
   vcpu_inject_pf
   uart16550_calc_baud_div
   uart16550_set_baud_rate
   console_init
   ptdev_activate_entry
No need to return 'entry' for ptdev_activate_entry
since the input parameter is 'entry'.
2) no need to check return value for the caller
   such as sbuf_put/console_putc/serial_puts/serial_get_rx_data

4dc39fdb8e HV:treewide:Add 16-bit atomic operations and update vpid type
There are some integer type conversions reported by static
analysis tool for vcpu id, number of created vcpus, and
vpid, to reduce these type conversions, redesign vcpu id,
number of created vcpus, and vpid type as uint16_t as per
their usage, related 16-bit atomic operations shall be
added in HV.
MISRA C requires that all unsigned constants should have the suffix 'U'
(e.g. 0xffU), but the assembler may not accept such C-style constants.

Add 16-bit atomic add/dec/store operations;
Update temporary variables type and parameters type of
related caller;
Update vpid type as uint16_t;
Replace Macro with constant value for CPU_PAGE_SIZE.

Note: According to SDM A.10, there are some bits defined
in the IA32_VMX_EPT_VPID_CAP MSR to support the INVVPID
instruction, these bits don't mean actual VPID, so
the vpid field in the data struct vmx_capability doesn't
be updated.

V1--V2:
	update comments for assembly code as per coding style;
