[PATCH bpf v2 0/1] bpf: btf: Fix endianness of bitfields

[Okash Khawaja]

Hi,

Following are the changes from v1:

- use compile time check for endianness
- factor out right_shift_bits from the check as it is same in both
- change size of bit shift variables to match length of bit offset in
BTF specification

Please note that I have considered non-big endians to be little endians
for our purposes. Let me know if you think that's a problem. We need to
then decide what to do in case neither of macros are defined.

Thanks,
Okash
