Pull networking updates from David Miller: "This is a re-do of the net-next pull request for the current merge window. The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

Pull drm updates from Dave Airlie: "Okay this is the big one, I was stalled on the fbdev pull req as I stupidly let fbdev guys merge a patch I required to fix a warning with some patches I had, they ended up merging the patch from the wrong place, but the warning should be fixed. In future I'll just take the patch myself! Outside drm: There are some snd changes for the HDMI audio interactions on haswell, they've been acked for inclusion via my tree. This relies on the wound/wait tree from Ingo which is already merged. Major changes: AMD finally released the dynamic power management code for all their GPUs from r600->present day, this is great, off by default for now but also a huge amount of code, in fact it is most of this pull request. Since it landed there has been a lot of community testing and Alex has sent a lot of fixes for any bugs found so far. I suspect radeon might now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable dynamic powermanagement for anyone. New drivers: Renesas r-car display unit. Other highlights: - core: GEM CMA prime support, use new w/w mutexs for TTM reservations, cursor hotspot, doc updates - dvo chips: chrontel 7010B support - i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell), Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp support (this time for sure) - nouveau: async buffer object deletion, context/register init updates, kernel vp2 engine support, GF117 support, GK110 accel support (with external nvidia ucode), context cleanups. - exynos: memory leak fixes, Add S3C64XX SoC series support, device tree updates, common clock framework support, - qxl: cursor hotspot support, multi-monitor support, suspend/resume support - mgag200: hw cursor support, g200 mode limiting - shmobile: prime support - tegra: fixes mostly I've been banging on this quite a lot due to the size of it, and it seems to okay on everything I've tested it on." * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (811 commits) drm/radeon/dpm: implement vblank_too_short callback for si drm/radeon/dpm: implement vblank_too_short callback for cayman drm/radeon/dpm: implement vblank_too_short callback for btc drm/radeon/dpm: implement vblank_too_short callback for evergreen drm/radeon/dpm: implement vblank_too_short callback for 7xx drm/radeon/dpm: add checks against vblank time drm/radeon/dpm: add helper to calculate vblank time drm/radeon: remove stray line in old pm code drm/radeon/dpm: fix display_gap programming on rv7xx drm/nvc0/gr: fix gpc firmware regression drm/nouveau: fix minor thinko causing bo moves to not be async on kepler drm/radeon/dpm: implement force performance level for TN drm/radeon/dpm: implement force performance level for ON/LN drm/radeon/dpm: implement force performance level for SI drm/radeon/dpm: implement force performance level for cayman drm/radeon/dpm: implement force performance levels for 7xx/eg/btc drm/radeon/dpm: add infrastructure to force performance levels drm/radeon: fix surface setup on r1xx drm/radeon: add support for 3d perf states on older asics drm/radeon: set default clocks for SI when DPM is disabled ...

2013-06-28lib: Move fonts from drivers/video/console/ to lib/fonts/Geert Uytterhoeven
Several drivers need font support independent of CONFIG_VT, cfr. commit 9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font support code selection logic"). Hence move the fonts and their support logic from drivers/video/console/ to its own library directory lib/fonts/.

2013-06-28reservation: cross-device reservation support, v4Maarten Lankhorst
This adds support for a generic reservations framework that can be hooked up to ttm and dma-buf and allows easy sharing of reservations across devices. The idea is that a dma-buf and ttm object both will get a pointer to a struct reservation_object, which has to be reserved before anything is done with the contents of the dma-buf. Changes since v1: - Fix locking issue in ticket_reserve, which could cause mutex_unlock to be called too many times. Changes since v2: - All fence related calls and members have been taken out for now, what's left is the bare minimum to be useful for ttm locking conversion. Changes since v3: - Removed helper functions too. The documentation has an example implementation for locking. With the move to ww_mutex there is no need to have much logic any more.

2013-05-21Merge tag 'v3.10-rc2' into drm-intel-next-queuedDaniel Vetter
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).

2013-04-30drm: Add struct drm_rect and assorted utility functionsVille Syrjälä
struct drm_rect represents a simple rectangle. The utility functions are there to help driver writers. v2: Moved the region stuff into its own file, made the smaller funcs static inline, used 64bit maths in the scaled clipping function to avoid overflows (instead it will saturate to INT_MIN or INT_MAX). v3: Renamed drm_region to drm_rect, drm_region_clip to drm_rect_intersect, and drm_region_subsample to drm_rect_downscale. v4: Renamed some function parameters, improve kernel-doc comments a bit, and actually generate documentation for drm_rect.[ch]. v5: s/RETUTRNS/RETURNS/ Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Acked-by: Dave Airlie <airlied@gmail.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: More updates for v3.10 The main additional change here is Lars-Peter's DMA work plus the platform conversions which have been tested - getting this in mainline will make life easier for development after the merge window. These factor a large chunk of code out of the drivers for the platforms using dmaengine, greatly simplifying development.

After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to just MATCH_SUBDEV. The v4l2-dbg utility is much better placed to match by name by just enumerating all bridge and subdev devices until chip_name.name matches.
