Subject[PATCH bpf-next 0/5] bpf trampoline for arm64
Date
Add bpf trampoline support for arm64. Most of the logic is the same as
x86.

Tested on qemu, result:
#55 fentry_fexit:OK
#56 fentry_test:OK
#58 fexit_sleep:OK
#59 fexit_stress:OK
#60 fexit_test:OK
#67 get_func_args_test:OK
#68 get_func_ip_test:OK
#101 modify_return:OK

Xu Kuohai (5):
arm64: ftrace: Add ftrace direct call support
bpf: Move is_valid_bpf_tramp_flags() to the public trampoline code
bpf, arm64: Impelment bpf_arch_text_poke() for arm64
bpf, arm64: bpf trampoline for arm64
selftests/bpf: Fix trivial typo in fentry_fexit.c
