Hmm, doesn't seem to work here. I still that triple fault in guest.
Can you add a printk to see what value is returned and why?
Argh, it's a off-by one bug in my userspace tool... So the CPU really
does support 0x80000008 and I'm just an idiot. :-)
So to explain this a bit more: I'm setting 0x80000000 to 0x80000008
but failing to install an entry for 0x80000008. I don't quite
understand why kvm_find_cpuid_entry() doesn't return NULL in this case?
cpuid is defined to return the highest entry if it doesn't find a match.
OK, then it's a bug of my own doing and we don't need to do anything in
the kernel.
