These headers are search along a search path until found. Typically that
path consists of two directories such as mach-ip22 followed by mach-generic
as last. This allows eleminating duplicated header files.
A bad side effect - users frequently forget adding files such as
cpu-features-override.h which contain a detailed description of the CPU
properties on a particular platform. Without a platform specific file
the kernel will basically fallback to generic code that is slow but
supports almost every CPU in the universe.
