[RFC][PATCH] arm64 support for vboxguest

[Christian Kujau <lists@nerdbynature.de>]

Hello,

now that VirtualBox able to run as a host on arm64 (e.g. the Apple M3 
processors) I was wondering if there are any plans to port the vboxguest 
driver to that platform? I added ARM64 to the Kconfig files (see below) on 
vboxguest and vboxsf, and also for vboxvideo, and it compiled just like 
that and at least vboxsf appears to work just fine.

I don't know how to test vboxvideo yet (the module loads just fine), but 
if we at least enable to option in the Kconfig file at least people would 
be able to test it :-)

Comments?

Thanks,
Christian.
