Merge branch 'filter-next'

Alexei Starovoitov says:

====================
BPF testsuite and cleanup

This patchset adds BPF testsuite and improves readability of classic
to internal BPF converter.

The testsuite helped to find 'negative offset bug' in x64 JIT that was
fixed by commit fdfaf64e ("x86: bpf_jit: support negative offsets")

It can be very useful for classic and internal JIT compiler developers.
Also it serves as performance benchmark.

x86_64/i386 pass all tests with and without JIT. arm32 JIT is failing
negative offset tests which are unsupported.

Internal BPF tests are much larger than classic tests to cover different
combinations of registers. Negative tests check correctness of classic
BPF verifier which must reject them.

Merge tag 'v3.10-rc2' into drm-intel-next-queued

Backmerge Linux 3.10-rc2 since the various (rather trivial) conflicts
grew a bit out of hand. intel_dp.c has the only real functional
conflict since the logic changed while dev_priv->edp.bpp was moved
around.

Also squash in a whitespace fixup from Ben Widawsky for
i915_gem_gtt.c, git seems to do something pretty strange in there
(which I don't fully understand tbh).
