====================
Enable the inline of kptr_xchg for arm64

From: Hou Tao <[e-mail]>

Hi,

The patch set is just a follow-up for "bpf: inline bpf_kptr_xchg()". It
enables the inline of bpf_kptr_xchg() and kptr_xchg_inline test for
arm64.

Please see individual patches for more details. And comments are always
welcome.
