    x86/asm: Add _ASM_ARG* constants for argument registers to <asm/asm.h> · 92e50158
    H. Peter Anvin authored
    commit 0e2e1600 upstream.
    
    i386 and x86-64 uses different registers for arguments; make them
    available so we don't have to #ifdef in the actual code.
    
    Native size and specified size (q, l, w, b) versions are provided.
