Subject: [PATCH bpf-next v2 0/2] bpf, arm64: enable kfunc call

Hi,

The simple patchset tries to enable kfunc call for arm64. Patch #1 just
overrides bpf_jit_supports_kfunc_call() to enable kfunc call and patch #2
add a test to ensure s32 is sufficient for kfunc offset.

Change Log:
v2: 
  * add a test to check whether imm will be overflowed for kfunc call

v1: https://lore.kernel.org/bpf/20220119144942.305568-1-houtao1@huawei.com

Hou Tao (2):
  bpf, arm64: enable kfunc call
  selftests/bpf: check whether s32 is sufficient for kfunc offset
