Would it make more sense to just use a real cryptographic hash function?
I don't think that any of the real kernel code is available this
You probably want to rotate by an odd number of bits... the point is to spread
out any pattern in the bytes.

Depending on availability, mix the RDRAND and RDTSC entropy together with
XOR. Only when neither is available should the i8254 be used. Update
the Kconfig documentation to reflect this. Additionally, since bits
used for entropy is masked elsewhere, drop the needless masking in
the get_random_long()
