Umm - they should be. Otherwise CPUID would be completely useless.

I double checked both the Intel and the x86-64 manual now and bit 19
of 0000_0001 is CLFLUSH

So cpufeature.h and the x86-64 test is correct

0000_0001 is supposed to be globally compatible. 8000_0001
is supposed to be compatible inside AMD CPUs (and 19 is reserved here)

Ivan confused me. Either he read the application note wrong or it is wrong.
