Pull bpf fixes from Alexei Starovoitov:
- Fix kCFI failures in JITed BPF code on arm64 (Sami Tolvanen, Puranjay
Mohan, Mark Rutland, Maxwell Bland)
- Disallow tail calls between BPF programs that use different cgroup
local storage maps to prevent out-of-bounds access (Daniel Borkmann)
- Fix unaligned access in flow_dissector and netfilter BPF programs
(Paul Chaignon)
- Avoid possible use of uninitialized mod_len in libbpf (Achill
Gilgenast)

bpf: Check flow_dissector ctx accesses are aligned
arm64/cfi,bpf: Support kCFI + BPF on arm64
cfi: Move BPF CFI types and helpers to generic code
cfi: add C CFI type macro
libbpf: Avoid possible use of uninitialized mod_len
bpf: Fix oob access in cgroup local storage
