[PATCH bpf-next 0/6] Misc improvements and few minor fixes

[Daniel Borkmann <daniel@iogearbox.net>]

Last batch of misc patches I had in queue: first one removes some left-over
bits from ULP, second is a fix in the verifier where we wrongly use register
number as type to fetch the string for the dump, third disables xadd on flow
keys and subsequent one removes the flow key type from check_helper_mem_access()
as they cannot be passed into any helper as of today. Next one lets map push,
pop, peek avoid having to go through retpoline, and last one has a couple of
minor fixes and cleanups for the ring buffer walk.

Thanks!
