pull-request: bpf 2024-06-14

We've added 8 non-merge commits during the last 2 day(s) which contain
a total of 9 files changed, 92 insertions(+), 11 deletions(-).

The main changes are:

1) Silence a syzkaller splat under CONFIG_DEBUG_NET=y in pskb_pull_reason()
   triggered via __bpf_try_make_writable(), from Florian Westphal.

2) Fix removal of kfuncs during linking phase which then throws a kernel
   build warning via resolve_btfids about unresolved symbols,
   from Tony Ambardar.

3) Fix a UML x86_64 compilation failure from BPF as pcpu_hot symbol
   is not available on User Mode Linux, from Maciej Żenczykowski.

4) Fix a register corruption in reg_set_min_max triggering an invariant
   violation in BPF verifier, from Daniel Borkmann.
