Userspace has no way to query if SEV has been disabled with the
sev module parameter of kvm-amd.ko. Actually it has one, but it
is a hack: do ioctl(KVM_MEM_ENCRYPT_OP, NULL) and check if it
returns EFAULT. Make it a little nicer by returning zero for
SEV enabled and NULL argument, and while at it document the
ioctl arguments.

Documentation: move Documentation/virtual to Documentation/virt2019-07-24T08:52:11ZChristoph Hellwighch@lst.de2019-07-24T07:24:49Zurn:sha1:2f5947dfcaecb99f2dd559156eecbeb7b95e4c02
Renaming docs seems to be en vogue at the moment, so fix on of the
grossly misnamed directories. We usually never use "virtual" as
a shortcut for virtualization in the kernel, but always virt,
as seen in the virt/ top-level directory. Fix up the documentation
to match that.
