That will be used by trace__sys_enter when we start combining the augmented syscalls:sys_enter_FOO + syscalls:sys_exit_FOO.

See https://www.spinics.net/lists/netdev/msg480099.html for the whole discussio, but to make the augmented_syscalls.c BPF program to get built and loaded successfully in a greater range of kernels, add an extra check. Related patch: a60dd35d ("bpf: change bpf_perf_event_output arg5 type to ARG_CONST_SIZE_OR_ZERO") That is in the kernel since v4.15, I couldn't figure why this is hitting me with 4.17.17, but adding the workaround discussed there makes this work with this fedora kernel and with 4.18.recent.

Using a value returned from probe_read_str() to tell how many bytes to copy using perf_event_output() has issues in some older kernels, like 4.17.17-100.fc27.x86_64, so separate the bounds checking done on how many bytes to copy to a separate variable, so that the next patch has only what is being done to make the test pass on older BPF validators.

Add default handler for non-jump instructions. This really only has an effect on instructions that compute a PC-relative address, such as 'adrp,' as seen in these couple of examples: BEFORE: adrp x0, ffff20000aa11000 <kallsyms_token_index+0xce000> AFTER: adrp x0, kallsyms_token_index+0xce000 BEFORE: adrp x23, ffff20000ae94000 <__per_cpu_load> AFTER: adrp x23, __per_cpu_load The implementation is identical to that of s390, but with a slight adjustment for objdump whitespace propagation (arm64 objdump puts spaces after commas, whereas s390's presumably doesn't). The mov__scnprintf() declaration is moved from s390's to arm64's instructions.c because arm64's gets included before s390's. Committer testing: Ran 'perf annotate --stdio2 > /tmp/{before,after}' no diff.
