James Hogan b620911086 KVM: MIPS: Implement kvm_arch_flush_shadow_all/memslot ... Implement the kvm_arch_flush_shadow_all() and kvm_arch_flush_shadow_memslot() KVM functions for MIPS to allow guest physical mappings to be safely changed. The general MIPS KVM code takes care of flushing of GPA page table entries. kvm_arch_flush_shadow_all() flushes the whole GPA page table, and is always called on the cleanup path so there is no need to acquire the kvm->mmu_lock. kvm_arch_flush_shadow_memslot() flushes only the range of mappings in the GPA page table corresponding to the slot being flushed, and happens when memory regions are moved or deleted. MIPS KVM implementation callbacks are added for handling the implementation specific flushing of mappings derived from the GPA page tables. These are implemented for trap_emul.c using kvm_flush_remote_tlbs() which should now be functional, and will flush the per-VCPU GVA page tables and ASIDS synchronously (before next entering guest mode or directly accessing GVA space).
