[Xen-devel] Re: [RFC] [PATCH] sysfs support for Xen attributes

Why not do the same thing that the Cell developers did for their
"special syscalls"?  Or at the least, make it a "real" syscall like the
ppc64 developers did.  It's not like there isn't a whole bunch of "prior
art" in the kernel today that you should be ignoring.

A hypercall syscall would be good in a lot of ways. For x86/x86_64 there are multiple hypervisors so we would need to make the syscall general enough to support more than one hypervisor.
