Thinking about it some more, this should be possible to do cleaner like 
this:

#ifdef CONFIG_X86_32
# ifdef __ASSEMBLY__
#  define __ASM_SEL(a,b) a
# else
#  define __ASM_SEL(a,b) " " #a " "
# endif
#else
# ifdef __ASSEMBLY__
#  define __ASM_SEL(a,b) b
# else
#  define __ASM_SEL(a,b) " " #b " "
# endif
#endif

#define _ASM_INC    _ASM_SEL(incl,incq)
#define _ASM_DEC    _ASM_SEL(decl,decq)

/* ... etc ... */
