Changes from v1:
- Use unsigned access for SKF_AD_HATYPE
- Added three more patches for other problems found.
Testing the BPF JIT on Cavium OCTEON (mips64) with the test-bpf module
identified some failures and unimplemented features.
With this patch set we get:
test_bpf: Summary: 305 PASSED, 0 FAILED, [85/297 JIT'ed]
Both big and little endian tested.
We still lack eBPF support, but this is better than nothing.
David Daney (5):
MIPS: uasm: Add support for LHU.
MIPS: BPF: Add JIT support for SKF_AD_HATYPE.
MIPS: BPF: Use unsigned access for unsigned SKB fields.
MIPS: BPF: Quit clobbering callee saved registers in JIT code.
MIPS: BPF: Fix multiple problems in JIT skb access helpers.
