This is only true on amd64.  More accurate would be:

#ifdef __amd64__
#define cpu_has_clflush (1)
#elif defined(__i386__)
#define cpu_has_clflush (cpu_feature & CPUID_CLFSH)
#else
#define cpu_has_clflush clflush_not_supported
#endif

Presumably you aren't planning to restrict all of OFED and drm2 to only
be used on amd64?
