    x86: unify include/asm/floppy_32/64.h
    
    Same file, except for whitespace, comment formatting and:
    
    32-bit: if((unsigned int) addr >= (unsigned int) high_memory)
    64-bit: if((unsigned long) addr >= (unsigned long) high_memory)
    
    where the latter can be used safely for both.
