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

[Pu Lehui]

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@xxxxxxxxxx
- Remove some trivial code

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