From: Scott Wood <scottwood@xxxxxxxxxxxxx>
Keeping two separate headers for e500-specific things was a
pain, and wasn't even organized along any logical boundary.
There was TLB stuff in <asm/kvm_e500.h> despite the existence of
arch/powerpc/kvm/e500_tlb.h, and nothing in <asm/kvm_e500.h> needed
to be referenced from outside arch/powerpc/kvm.
