James Hogan c771607af9 MIPS: KVM: Add Config4/5 and writing of Config registers ... Add Config4 and Config5 co-processor 0 registers, and add capability to write the Config1, Config3, Config4, and Config5 registers using the KVM API. Only supported bits can be written, to minimise the chances of the guest being given a configuration from e.g. QEMU that is inconsistent with that being emulated, and as such the handling is in trap_emul.c as it may need to be different for VZ. Currently the only modification permitted is to make Config4 and Config5 exist via the M bits, but other bits will be added for FPU and MSA support in future patches. Care should be taken by userland not to change bits without fully handling the possible extra state that may then exist and which the guest may begin to use and depend on.
