    KVM/MIPS32: Binary patching of select privileged instructions. · 50c83085
    Sanjay Lal authored
    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.
