Subject: [PATCH bpf-next v3 0/6] Support riscv jit to provide

patch 1 fix an issue that could not print bpf line info due
to data inconsistency in 32-bit environment.

patch 2 add support for riscv jit to provide bpf_line_info.
"test_progs -a btf" and "test_bpf.ko" all test pass, as well
as "test_verifier" and "test_progs" with no new failure ceses.

patch 3-6 make some trival cleanup.

v3:
- split kernel changes, libbpf changes, and selftests/bpf changes
into separate patches. (Andrii)
- shorten the name of jited_linfo_addr to avoid line break. (John)
- rename prologue_offset to body_len to make it more sense. (Luke)

v2: https://lore.kernel.org/bpf/20220429014240.3434866-1-pulehui@huawei.com
- Remove some trivial code

v1: https://lore.kernel.org/bpf/20220426140924.3308472-1-pulehui@huawei.com

Pu Lehui (6):
  bpf: Unify data extension operation of jited_ksyms and jited_linfo
  riscv, bpf: Support riscv jit to provide bpf_line_info
  bpf: Correct the comment about insn_to_jit_off
  libbpf: Unify memory address casting operation style
  selftests/bpf: Unify memory address casting operation style
  selftests/bpf: Remove the casting about jited_ksyms and jited_linfo
