Notes:
v4:
- moved rdtsc to arch/x86/include/arch/lib.h
- added a rdtsc_ordered implementation to serialize rdtsc
- simplified since_boot_time function
- still need to have Andr

Thanks for the patch. Looking a bit more at the code over the weekend,
I figured out what that BUILD_BUG_ON() is for -- in afl_harness.c, we
statically allocate a buffer of size INPUT_SIZE to hold the fuzz data.
The BUILD_BUG_ON() is to
The maximum size for the input size was set to INPUT_SIZE, which is actually
the size of the data array inside the fuzz_corpus structure and so was not
abling user (or AFL) to fill in the whole structure. Changing to
sizeof(struct fuzz_corpus) correct this problem.

ds should rather be :
DATA_OFFSET < size < sizeof (struct fuzz_corpus)
but maybe I am missing something here
Thanks,
