Atomics support in bpf has already been done by "Atomics for eBPF"
patch series [1], but it only adds support for x86, and this patchset
adds support for arm64.

Patch #1 & patch #2 are arm64 related. Patch #1 moves the common used
macro AARCH64_BREAK_FAULT into insn-def.h for insn.h. Patch #2 adds
necessary encoder helpers for atomic operations.

Applied to arm64 (for-next/insn), thanks!

Daniel -- let's give this a day or so in -next, then if nothing catches
fire you're more than welcome to pull this branch as a base for the rest
of the series.

Cheers,
