Linux 4.4 rc1

As usual, the full shortlog is much too big to post, so appended isthe usual shortlog of just my merges, which just shows who I did pullsfrom, with a very short comment on each merge.Just looking at the patch itself, things look fairly normal at a highlevel, possibly a bit more driver-heavy than usual with about 75% ofthe patch being drivers, and 10% being architecture updates. Theremaining 15% is documentation, filesystem, core networking (asopposed to network drivers), tooling and some core infrastructure.The driver changes are all over, although staging, networking and GPUdrivers stand out (and those three areas account for over half of thedriver changes - roughly 40% of the whole patch).On the architecture side, ARM (when counting both 32-bit and 64-bit)accounts for about half the changes, with x86, powerpc, mips, chrisand s390 accounting for the other half.Go out and test.
