[PATCH 0/2] arm64: bpf: add BPF_ST and BPF_XADD instructions support
From: Yang Shi
Date: Tue Nov 10 2015 - 18:00:26 EST
Current ARM64 BPF JIT doesn't have store immediate and XADD instructions
support, and aarch64 doesn't have native instructions for them. Implement
them in instruction sequence. For detail, please refer to the commit log.
The implementation is tested by test_bpf kernel module.
The patches are applied after my BPF JIT stack fix .
