Hi,

The patchset addresses two issues in bpf line info for arm64:

(1) insn_to_jit_off only considers the body itself and ignores
     prologue before the body. Fixed in patch #1.

(2) insn_to_jit_off passed to bpf_prog_fill_jited_linfo() is
     calculated in instruction granularity instead of bytes
     granularity. Fixed in patch #2.

Comments are always welcome.

Regards,
Tao

Change Log:
v2:
 * split into two independent patches (from Daniel)
 * use AARCH64_INSN_SIZE instead of defining INSN_SIZE

v1: https://lore.kernel.org/bpf/[e-mail]

Hou Tao (2):
  bpf, arm64: call build_prologue() first in first JIT pass
  bpf, arm64: calculate offset as byte-offset for bpf line info
