The main changes are:

1) Batch of BPF sockmap fixes found when running against NGINX TCP tests, from John Fastabend.

2) Fix a memleak in the LRU{,_PERCPU} hash map when bucket locking fails, from Anton Protopopov.

3) Init the BPF offload table earlier than just late_initcall, from Jakub Kicinski.

4) Fix ctx access mask generation for 32-bit narrow loads of 64-bit fields, from Will Deacon.

5) Remove a now unsupported __fallthrough in BPF samples, from Andrii Nakryiko.

6) Fix a typo in pkg-config call for building sign-file, from Jeremy Sowden.
