KVM on VMI

Hi,

I more or less accidently stumbled across a problem when compiling KVM on the VMI-enabled kernel. Even though that's pretty much useless right now, I think there might be a day, VMware will emulate VM extensions, in VMs, so we should probably not keep KVM from running under VMI.

The problem is that usually load_ldt is #defined, while in VMI it's a static void function. This clashes with the way KVM detects if load_ldt is defined already. To circumvent this, I just extended the check so we're not redefining load_ldt when VMI is activated.

+#if !(defined(load_ldt) || defined(CONFIG_X86_VMI))
 static inline void load_ldt(u16 sel)
 {
 	asm("lldt %0" : : "rm"(sel));

I fixed this in another way, by renaming prefixing load_ldt (and a bunch of other functions) with kvm_.
