MIPS: asm/tlb.h: Add UNIQUE_GUEST_ENTRYHI() macro
Add a distinct UNIQUE_GUEST_ENTRYHI() macro for invalidation of guest
TLB entries by KVM, using addresses in KSeg1 rather than KSeg0. This
avoids conflicts with guest invalidation routines when there is no EHINV
bit to mark the whole entry as invalid, avoiding guest machine check
exceptions on Cavium Octeon III.
