KVM/MIPS32: Entry point for trampolining to the guest and trap handlers.
- __kvm_mips_vcpu_run: main entry point to enter guest, we save kernel context, load
up guest context from and ERET to guest context.
- mips32_exception: L1 exception handler(s), save k0/k1 and jump to main handlers.
- mips32_GuestException: Generic exception handlers for exceptions/interrupts while in
guest context. Save guest context, restore some kernel context and jump to
main 'C' handler: kvm_mips_handle_exit()
