This patch set enables using bpf2bpf calls together with tail calls on arm64.
Patch 1 was borrowed from an RFC series for MIPS JIT [1].
Patch 2 gives an explanation of tweaks needed to arm64 BPF JIT.

  bpf: arm64: Keep tail call count across bpf2bpf calls

  bpf: x64: Add predicate for bpf2bpf with tailcalls support in JIT
