Hi Vineet and all,

Here is the second revision of the patch series implementing
the following two features for ARC:
- HAVE_REGS_AND_STACK_ACCESS_API
- HAVE_SYSCALL_TRACEPOINTS

Adding these features enables more BPF programs for ARC kernels,
including KPROBE, TRACEPOINT, PERF_EVENT program types.

Regards,
Sergey

v1 -> v2:

- drop path with uapi for BPF_PROG_TYPE_PERF_EVENT program type: send it via bpf mailing list
- add patch with ARCv2 changes for kprobe disasm

Sergey Matyukevich (4):
  ARC: enable HAVE_REGS_AND_STACK_ACCESS_API feature
  ARC: entry: fix syscall_trace_exit argument
  ARC: implement syscall tracepoints
  ARC: disasm: handle ARCv2 case in kprobe get/set functions
