James Hogan 7170bdc777 MIPS: Add return errors to protected cache ops ... The protected cache ops contain no out of line fixup code to return an error code in the event of a fault, with the cache op being skipped in that case. For KVM however we'd like to detect this case as page faulting will be disabled so it could happen during normal operation if the GVA page tables were flushed, and need to be handled by the caller. Add the out-of-line fixup code to load the error value -EFAULT into the return variable, and adapt the protected cache line functions to pass the error back to the caller.
