    <linux/hash.h>: Add support for architecture-specific functions · 468a9428

    This is just the infrastructure; there are no users yet.
    
    This is modelled on CONFIG_ARCH_RANDOM; a CONFIG_ symbol declares
    the existence of <asm/hash.h>.
    
    That file may define its own versions of various functions, and define
    HAVE_* symbols (no CONFIG_ prefix!) to suppress the generic ones.
    
    Included is a self-test (in lib/test_hash.c) that verifies the basics.
    It is NOT in general required that the arch-specific functions compute
    the same thing as the generic, but if a HAVE_* symbol is defined with
    the value 1, then equality is tested.
