[PATCH 00/14] arm64: eBPF JIT compiler

[Zi Shen Lim]

This series implements eBPF JIT compiler for arm64.
Please see [14/14] for change log.

Patches [1-13/14] implement code generation functions.
Patch [14/14] implements the actual eBPF JIT compiler.

Many thanks to everyone who's reviewed the code from
RFCv1->RFCv3, especially Alexei for BPF bits, and Will
for ARM64 codegen bits :)

BTW, I'm happy to maintain arch/arm64/net (i.e. arm64 BPF bits).
Should I add a patch updating MAINTAINERS as Patch 15?

This series requires a patch that exports a function
from net/core (resulting from RFCv1 discussion). This patch
has been merged into net-next @ 9f12fbe603f7
("net: filter: move load_pointer() into filter.h").

This series applies against net-next and is tested working
with lib/test_bpf on ARMv8 Foundation Model.
