Merge branch 'bpf-tail-calls-in-sleepable-programs'

Jiri Olsa says:

====================
this patchset allows sleepable programs to use tail calls.

At the moment we need to have separate sleepable uprobe program
to retrieve user space data and pass it to complex program with
tail calls. It'd be great if the program with tail calls could
be sleepable and do the data retrieval directly.
