For BXT, DDI buf idle timeout delay needs to be increased to 16us. Since this is a timeout value and we return as soon as the condition is realized, no penalty incurred for other platforms. v2: - remove TIMEOUT macro used only at a single place (Daniel) Suggested-by:

drm/panel: Changes for v4.1-rc1 This set of changes adds support for a whole bunch of new panels, mostly simple ones. There's now also support for panels to provide display timings rather than fixed modes, which should allow panels to work with a larger number of display drivers. Eventually drivers should migrate to this new interface and the fixed modes removed from panels. There are also a couple of sparse fixes for the PS8622 and PS8625 bridge drivers. * tag 'drm/panel/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/panel: Add support for Ampire AM-800480R3TMQW-A1H 800x480 7" panel of: Add vendor prefix for Ampire Co., Ltd. drm/panel: Add display timing for HannStar HSD070PWW1 drm/panel: simple: Add display timing support drm/panel: Add display timing support drm/panel: Add support for OrtusTech COM43H4M85ULC panel of: Add vendor prefix for Ortus Technology Co., Ltd. drm/panel: Add bus format for Giantplus GPG482739QS5 panel drm/panel: simple: Add support for AUO b101ean01 panel drm/panel: simple: Add support for Innolux ZJ070NA-01P drm/panel: simple: Add support for Innolux AT043TN24 drm/panel: simple: Add support for Shelly SCA07010-BFN-LNN drm/panel: simple: Add support for Samsung LTN140AT29 panel drm: Remove unused DRM_MODE_OBJECT_BRIDGE drm/bridge: ptn3460: Fix sparse warnings drm/bridge: ps8622: Fix sparse warnings drm/bridge: Add I2C based driver for ps8622/ps8625 bridge

drm/tegra: Changes for v4.1-rc1 Perhaps the most noteworthy change in this set is the implementation of a hardware VBLANK counter using host1x syncpoints. The SOR registers can now be dumped via debugfs, which can be useful while debugging. The IOVA address space maintained by the driver can also be dumped via debugfs. Other than than, these changes are mostly cleanup work, such as making register names more consistent or removing unused code (that was left over after the atomic mode-setting conversion). There's also a fix for eDP that makes the driver cope with firmware that already initialized the display (such as the firmware on the Tegra-based Chromebooks). * tag 'drm/tegra/for-4.1-rc1' of git://anongit.freedesktop.org/tegra/linux: drm/tegra: sor: Reset during initialization drm/tegra: gem: Return 64-bit offset for mmap(2) drm/tegra: hdmi: Name register fields consistently drm/tegra: hdmi: Resets are synchronous drm/tegra: dc: Document tegra_dc_state_setup_clock() drm/tegra: dc: Remove unused callbacks drm/tegra: dc: Remove unused function drm/tegra: dc: Use base atomic state helpers drm/atomic: Add helpers for state-subclassing drivers drm/tegra: dc: Implement hardware VBLANK counter gpu: host1x: Export host1x_syncpt_read() drm/tegra: sor: Dump registers via debugfs drm/tegra: sor: Registers are 32-bit drm/tegra: Provide debugfs file for the IOVA space drm/tegra: dc: Check for valid parent clock

Pull networking fixes from David Miller: 1) In TCP, don't register an FRTO for cumulatively ACK'd data that was previously SACK'd, from Neal Cardwell. 2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup, from Cong WANG. 3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also from Cong WANG. 4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel. 5) When we encapsulate for a tunnel device, skb->sk still points to the user socket. So this leads to cases where we retraverse the ipv4/ipv6 output path with skb->sk being of some other address family (f.e. AF_PACKET). This can cause things to crash since the ipv4 output path is dereferencing an AF_PACKET socket as if it were an ipv4 one. The short term fix for 'net' and -stable is to elide these socket checks once we've entered an encapsulation sequence by testing xmit_recursion. Longer term we have a better solution wherein we pass the tunnel's socket down through the output paths, but that is way too invasive for 'net' and -stable. From Hannes Frederic Sowa. 6) l2tp_init() failure path forgets to unregister per-net ops, from Cong WANG. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net/mlx4_core: Fix error message deprecation for ConnectX-2 cards net: dsa: fix filling routing table from OF description l2tp: unregister l2tp_net_ops on failure path mvneta: dont call mvneta_adjust_link() manually ipv6: protect skb->sk accesses from recursive dereference inside the stack netns: don't allocate an id for dead netns Revert "netns: don't clear nsid too early on removal" ip6mr: call del_timer_sync() in ip6mr_free_table() net: move fib_rules_unregister() under rtnl lock ipv4: take rtnl_lock and mark mrt table as freed on namespace cleanup tcp: fix FRTO undo on cumulative ACK of SACKed range xen-netfront: transmit fully GSO-sized packets -

According to description in 'include/net/dsa.h', in cascade switches configurations where there are more than one interconnected devices, 'rtable' array in 'dsa_chip_data' structure is used to indicate which port on this switch should be used to send packets to that are destined for corresponding switch. However, dsa_of_setup_routing_table() fills 'rtable' with port numbers of the _target_ switch, but not current one. This commit removes redundant devicetree parsing and adds needed port number as a function argument. So dsa_of_setup_routing_table() now just looks for target switch number by parsing parent of 'link' device node. To remove possible misunderstandings with the way of determining target switch number, a corresponding comment was added to the source code and to the DSA device tree bindings documentation file. This was tested on a custom board with two Marvell 88E6095 switches with following corresponding routing tables: { -1, 10 } and { 8, -1 }.

We should not consult skb->sk for output decisions in xmit recursion levels > 0 in the stack. Otherwise local socket settings could influence the result of e.g. tunnel encapsulation process. ipv6 does not conform with this in three places: 1) ip6_fragment: we do consult ipv6_npinfo for frag_size 2) sk_mc_loop in ipv6 uses skb->sk and checks if we should loop the packet back to the local socket 3) ip6_skb_dst_mtu could query the settings from the user socket and force a wrong MTU Furthermore: In sk_mc_loop we could potentially land in WARN_ON(1) if we use a PF_PACKET socket ontop of an IPv6-backed vxlan device. Reuse xmit_recursion as we are currently only interested in protecting tunnel devices. Cc: Jiri Pirko <jiri@resnulli.us> Signed-off-by:
