This patch series introduces several optimizations to the arm64 BPF JIT.
The optimizations make use of arm64 immediate instructions to avoid
loading BPF immediates to temporary registers, when possible.

In the process, we discovered two bugs in the logical immediate encoding
function in arch/arm64/kernel/insn.c using Serval. The series also fixes
the two bugs before introducing the optimizations.

Applied to arm64 (for-next/bpf), thanks!
