It works on other arches like x86/aarch/powerpc, it does not work on mips platform. Just because these header files are not used with path prefix on mips system, it brings out such problem.
Today if we modify generic kvm code, it maybe brings out problem with other modules tommorrow. Else we declare that these files can be defined locally on all modules: cpu-feature-overrides.h floppy.h ide.h ioremap.h irq.h kernel-entry-init.h kmalloc.h mangle-port.h mc146818rtc.h
