In my understanding, this code provides "make hvconfig" as a shorthand for "make hv_guest.config" Please do not do this. See "xenconfig" as a bad example. "make xenconfig" is a shorthand of "make xen.config". This exists to save just one character typing. If I allow this, people would push more and more random pointless shorthands, which are essentially unrelated to kconfig. kvmconfig and xenconfig are just historical mistakes. Please drop the changes to scripts/kconfig/Makefile. Also, please do not use misleading "kconfig:" for the subject prefix. You can use the subject prefix "hyper-v:" or something.
