[PATCH 0/4] ARC: add missing bits for better BPF support

[Sergey Matyukevich]

Hi Vineet and all,

This patch set implements 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
