From: "Luis R. Rodriguez" <[email protected]>
Resending to the maintainers that it was recommended to try.
Ingo, Thomas, Andrew, who should this go through? Please note
that the Kconfig maintainer is not available anymore and it
was recommended this go through that person first, meanwhile
while that is ironed out it was suggested I try with any of
you.

x86, platform, xen, kconfig: clarify kvmconfig is for kvm

We'll be adding options for xen as well.

From: "Luis R. Rodriguez" <[email protected]>
This lets you build a kernel which can support xen dom0
or xen guests by just using:
make xenconfig
on both x86 and arm64 kernels. This also splits out the
options which are available currently to be built with x86
and 'make ARCH=arm64' under a shared config.
Technically xen supports a dom0 kernel and also a guest
kernel configuration but upon review with the xen team
since we don't have many dom0 options its best to just
combine these two into one.

This doesn't work because neither CONFIG_HYPERVISOR_GUEST in
arch/x86/configs/xen.config nor CONFIG_PARAVIRT in
kernel/configs/xen.config get enabled.
make kvmconfig does this appropriately.
You can test this with make {allno,def}config; make xenconfig. Notice
there's no difference with your patchset.

Thanks, I'll fix.
