Updates for arm64 eBPF JIT.
The main addition here is implementation of bpf_tail_call.

#1: Fix missing header inclusion in linux/bpf.h.
#2: Add bpf_tail_call for arm64.
#3,4: Optimizations to reduce instruction count for jitted code.

Changes since v1:
 - Added patch #1 to address build error due to missing header inclusion
   in linux/bpf.h. (Thanks to suggestion and ack by Daniel Borkmann)
   Ordered it ahead of bpf_tail_call patch #2 so build error is not
   triggered.

Zi Shen Lim (4):
  bpf: fix missing header inclusion
  arm64: bpf: implement bpf_tail_call() helper
  arm64: bpf: optimize JMP_CALL
  arm64: bpf: optimize LD_ABS, LD_IND
