Since all the files are in arch/mips/kvm/, there's no need of the prefixes
"kvm_" and "kvm_mips_".

MIPS KVM uses mips32_SyncICache to synchronise the icache with the
dcache after dynamically modifying guest instructions or writing guest
exception vector. However this uses rdhwr to get the SYNCI step, which
causes a reserved instruction exception on Ingenic XBurst cores.
It would seem to make more sense to use local_flush_icache_range()
instead which does the same thing but is more portable.

Currently, the following instructions are translated:
- CACHE (indexed)
- CACHE (va based): translated to a SYNCI, overkill on D-CACHE operations,
but still much faster than a trap.
- mfc0/mtc0: the virtual COP0 registers for the guest are implemented as
2-D array.
[COP#][SEL] and this is mapped into the guest kernel address space @ VA 0x0.
mfc0/mtc0 operations are transformed to load/stores.
