Hi David,
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix several bugs in BPF sparc JIT, that is, convergence for fused
branches, initialization of frame pointer register, and moving all
arguments into output registers from input registers in prologue
to fix BPF to BPF calls, from David.
2) Fix a bug in arm64 JIT for fetching BPF to BPF call addresses where
they are not guaranteed to fit into imm field and therefore must be
retrieved through prog aux data, from Daniel.
3) Explicitly add all JITs to MAINTAINERS file with developers able to
help out in feature development, fixes, review, etc.

Thanks a lot!
