This is a experimental feature for arm64 as linux kernel has
not enable kvm ptp for arm64.
ptp_kvm need co-work from host and guest, so you need add this
patch both to your guest and host. Host kernel version is better
lower than 5.0 and higher than 4.19.
another version of this patch base on kernel v5.3 is under review in kernel upstream, refer to [1]
to see the full info.

This will allow to test local changes to the kernel as well it will allow
us to have vmlinuz or vmlinux with virtiofs.

As per the comments in security.conf, the intention was to
enable STACKPROTECTOR and STACKPROTECTOR_STRONG.
The current config leaves them unset in the final .config
and also prevents other fragments from overriding the setting.
Set both to =y as indicated in the comments.

common/DAX:
- ARCH_ENABLE_MEMORY_HOTPLUG: not needed (auto-selected)
- ARCH_HAS_ZONE_DEVICE: already automatically selected. This is
also removed in future kernels, so let's go ahead and drop.
- RADIX_TREE_MULTIORDER: already autoselected, and dropped in future
kernels
common/net:
- NF_NAT_NEEDED, NF_NAT_PROTO_*: these don't exist in newer kernels, as
they are refactored and unecessary in the upstream kernel. Keep them for
now, but consider dropping if we move to newer LTS. These are part of
whitelist of options we expect to be dropped with newer kernels in our
fragment building.
- NF_NAT_MASQUERADE_IPV4: this is a select, not a tristate. Also, in
the future much of the ipv4/ipv6 nat code is combined, so this config
will not exist in newer kernels. Dropped.
- INET6_XFRM_MODE_* are not needed on newer kernels. While I'm not
confident they are needed today for Kata, we will just note them and add
to whitelist for options we expect to be dropped with newer kernels in
our fragment building.
- MAY_USE_DEVLINK: removed in future kernels, and should not be needed
anyway. Dropped.
x86_64/DAX:
- ARCH_HAS_HMM: should not be needed, and is dropped in future kernels.
Dropped

These will be handled directly from virtio-fs gitlab, which is utilized
when experimental support is requested in kernel build.

Experimental kernel is much newer, and many configuration options have
dropped since 4.19. Let's use a whitelist to itemize what we expect to
be dropped in the final config if experimental kernel us utilized.

This isn't available in the baseline kernel, necessarily. Only
add these config options if an experimental kernel is being used.

Adding option `-e` to support experimental flag. When selected, the
kernel for virtio-fs is utilized instead of standard kernel.org.
This is a bit more hack-ish than I'd prefer, sorry.

Now we are using the fragments, drop the x86_64 4.19 config file
so we default to fragment mode.

Add the framework to build kernel config files from trees
of kernel fragments.
If no fragment directory is found for the requested kernel
version and architecture then revert to looking for a whole
prebuilt kernel config file instead.

This patches adds virtio-fs capability to the kata kernel along with
config changes to enable the same on kata by default. The system will
only be exercised when `shared_fs` is set to `virtio-fs` in the kata
configuration file. the default still remains to be 9p
