Junjie Mao db62c23d81 HV: vioapic: use uint8_t for pins
IOAPIC pins always fit in 8-bit and we already use uint8_t for virt_pins. This
patch converts pins in vioapic to uint8_t.

This is based on Arindam's previous patch ("was: hv: Cleanup and optimise
vioapic.c"), with SOS boot failure resolved, format string updated, complex
arithmetic expression with implicit type conversion decoupled. Also make some
local variables representing interrupt vectors uint32_t.

Junjie Mao ecce1e6ae4 HV: instr_emul: make integer conversion explicit
This patch makes necessary integer narrowing and/or signedness conversion
explicit.

While some narrowing are expected behavior, the correctness of the others relies
on the specifications of some interfaces (e.g. the higher 32-bit of what
exec_vmread() returns is all 0s if the given field is 32-bit). Add a stub
for now to avoid missing them.

Junjie Mao ab156c9633 HV: instr_emul: convert return value of get_vmcs_field to unsigned
get_vmcs_field() returns a VMCS field offset which is normally unsigned, but it
also returns negatives (-1 here) on invalid arguments. Following the convention
we use for vectors, pins, etc., use a special unsigned value to indicate such
errors.

v1 -> v2:

    * Use a special value (VMX_INVALID_VMCS_FIELD) instead of a seperate output
      parameter to indicate errors.

An immediate reset or power down will cause a loss of write content.
The cause is the data write to disk is at cache within a short

An explicit fsync() forces to sync the data to storage to prevent

David B. Kinder b0deb1b5bd doc: add support for kerneldoc API tools
Some ACRN kernel components are using the API documentation methods of
the Linux kernel.  While they use Sphinx for generating their
documentation, they don't use doxygen to collect the API information as
we do for the rest of the project.  Instead, they use their own tools
called "kerneldoc".  This PR incorporates those tools into our
documentation build process.

There is a prescribed directory structure for this to work: that the
acrn-hypervisor and acrn-kernel repos are cloned to sibling folders,
e.g.:

    projectacrn
       acrn-hypervisor
       acrn-kernel

so that documentation references from acrn_hypervisor/doc can access the
source code in ../../acrn-kernel to do the kerneldoc processing.  A full
display of the kerneldoc API material for a source file in the
acrn-kernel tree can be done using a sphinx extension directive:

    .. kernel-doc:: /tools/virtio/linux/scatterlist.h

where the assumed root of these file references is ../../acrn-kernel.

The format for kerneldoc comments is documented in
https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html and
references to kerneldoc API material in .rst files is documented in
https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html#including-kernel-doc-comments

Without options, the kernel-doc directive includes all documentation
comments from the source file. With options, you can display subsets of
these comments.

The intention is to limit use of kerneldoc comments to the acrn-kernel
repo and not use them elsewhere within the ACRN project (where doxygen
comments are expected.)

While I'd prefer NOT to include the kerneldoc perl script here (it is
already in the acrn-kernel/sphinx folder), I don't want to create a
dependency on the acrn-kernel folder existing for documentation
generation, but this might be unavoidable once we have part of the API
material coming from there.  We can update this in a later PR.
