git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "The biggest change in this update is the unification of HD-audio codec parsers. Now the HD-audio codec is parsed in a generic parser code which is invoked by each HD-audio codec driver. Some background information is found in David Henningsson's blog entry: http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/ Other than that, some random updates/fixes like USB-audio and a bunch of small AoC updates as usual. Highlights: - Unification of HD-audio parser code (aka generic parser) - Support of new Intel HD-audio controller, new IDT codecs - Fixes for HD-audio HDMI audio hotplug - Haswell HDMI audio fixup - Support of Creative CA0132 DSP code - A few fixes of HDSP driver - USB-audio fix for Roland A-PRO, M-Audio FT C600 - Support PM for aloop driver (and fixes Oops) - Compress API updates for gapless playback support For ASoC part: - Support for a wider range of hardware in the compressed stream code - The ability to mute capture streams as well as playback streams while inactive - DT support for AK4642, FSI, Samsung I2S and WM8962 - AC'97 support for Tegra - New driver for max98090, replacing the stub which was there - A new driver from Dialog Note that due to dependencies, DTification of DMA support for Samsung platforms (used only by the and I2S driver and SPI) is merged here as well."

2013-02-21ARM: 7654/1: Preserve L_PTE_VALID in pte_modify()Catalin Marinas
Following commit 26ffd0d4 (ARM: mm: introduce present, faulting entries for PAGE_NONE), if a page has been mapped as PROT_NONE, the L_PTE_VALID bit is cleared by the set_pte_ext() code. With LPAE the software and hardware pte share the same location and subsequent modifications of pte range (change_protection()) will leave the L_PTE_VALID bit cleared. This patch adds the L_PTE_VALID bit to the newprot mask in pte_modify().

2013-02-21ARM: 7653/2: do not scale loops_per_jiffy when using a constant delay clockNicolas Pitre
When udelay() is implemented using an architected timer, it is wrong to scale loops_per_jiffy when changing the CPU clock frequency since the timer clock remains constant. The lpj should probably become an implementation detail relevant to the CPU loop based delay routine only and more confined to it. In the mean time this is the minimal fix needed to have expected delays with the timer based implementation when cpufreq is also in use.

Pull networking update from David Miller: 1) Checkpoint/restarted TCP sockets now can properly propagate the TCP timestamp offset. From Andrey Vagin. 2) VMWARE VM VSOCK layer, from Andy King. 3) Much improved support for virtual functions and SR-IOV in bnx2x, from Ariel ELior. 4) All protocols on ipv4 and ipv6 are now network namespace aware, and all the compatability checks for initial-namespace-only protocols is removed. Thanks to Tom Parkin for helping deal with the last major holdout, L2TP. 5) IPV6 support in netpoll and network namespace support in pktgen, from Cong Wang. 6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration Protocol (MVRP) support, from David Ward. 7) Compute packet lengths more accurately in the packet scheduler, from Eric Dumazet. 8) Use per-task page fragment allocator in skb_append_datato_frags(), also from Eric Dumazet. 9) Add support for connection tracking labels in netfilter, from Florian Westphal. 10) Fix default multicast group joining on ipv6, and add anti-spoofing checks to 6to4 and 6rd. From Hannes Frederic Sowa. 11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern times, rearrange inet frag datastructures for better cacheline locality, and move more operations outside of locking. From Jesper Dangaard Brouer. 12) Instead of strict master <--> slave relationships, allow arbitrary scenerios with "upper device lists". From Jiri Pirko. 13) Improve rate limiting accuracy in TBF and act_police, also from Jiri Pirko. 14) Add a BPF filter netfilter match target, from Willem de Bruijn. 15) Orphan and delete a bunch of pre-historic networking drivers from Paul Gortmaker. 16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although this still needs some minor bug fixing before it's %100 correct in all cases. 17) Handle unresolved IPSEC states like ARP, with a resolution packet queue. From Steffen Klassert. 18) Remove TCP Appropriate Byte Count support (ABC), from Stephen Hemminger. This was long overdue. 19) Support SO_REUSEPORT, from Tom Herbert. 20) Allow locking a socket BPF filter, so that it cannot change after a process drops capabilities. 21) Add VLAN filtering to bridge, from Vlad Yasevich. 22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in the ipv6 routes, from YOSHIFUJI Hideaki. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1538 commits) ipv6: fix race condition regarding dst->expires and dst->from. net: fix a wrong assignment in skb_split() ip_gre: remove an extra dst_release() ppp: set qdisc_tx_busylock to avoid LOCKDEP splat atl1c: restore buffer state net: fix a build failure when !CONFIG_PROC_FS net: ipv4: fix waring -Wunused-variable net: proc: fix build failed when procfs is not configured Revert "xen: netback: remove redundant xenvif_put" net: move procfs code to net/core/net-procfs.c qmi_wwan, cdc-ether: add ADU960S bonding: set sysfs device_type to 'bond' bonding: fix bond_release_all inconsistencies b44: use netdev_alloc_skb_ip_align() xen: netback: remove redundant xenvif_put net: fec: Do a sanity check on the gpio number ip_gre: propogate target device GSO capability to the tunnel device ip_gre: allow CSUM capable devices to handle packets bonding: Fix initialize after use for 3ad machine state spinlock bonding: Fix race condition between bond_enslave() and bond_3ad_update_lacp_rate() ...

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc These changes contain the OMAP USB related platform data changes that were dropped from linux next because of the merge conflicts as requested by me and Olof. The reason was that at this point we really should be able to do the arch/arm related changes separately from driver changes to avoid dependencies between branches. These patches were initially part of the USB related MFD patches. Based on our comments, Roger Quadros quickly reworked these patches into a shared branch between ARM SoC tree and the MFD tree, then separate patches for the OMAP platform data and MFD driver. Note that this branch will conflict with c1d1cd597fc7 ("ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device code").

Also, deal with the semantic conflict of the change made to net/ipv6/xfrm6_policy.c A missing rt6->n neighbour release was added to 'net', but in 'net-next' we no longer cache the neighbour entries in the ipv6 routes so that change is not appropriate there.

After discussion on the linux-sh mailing list and reference to the hardware documentation it appears that 'TMU00', 'TMU01' and 'TMU02' use a common clock. The sh_tmu.1 portion of this change resolves a regression introduced in 58079fa7d54a0929d304054ee759187a2ccd3cdf (ARM: shmobile: r8a7779: Correct TMU clock support) and fixes a regression introduced by that patch.

When running in BE mode we see the values in mm->context.id are stored with the highest value first, so the LDR in the arch/arm/mm/proc-macros.S reads the wrong part of this field. To resolve this, change the LDR in the mmid macro to load from +4.

2013-02-16ARM: 7646/1: mm: use static_vm for managing static mapped areasJoonsoo Kim
A static mapped area is ARM-specific, so it is better not to use generic vmalloc data structure, that is, vmlist and vmlist_lock for managing static mapped area. And it causes some needless overhead and reducing this overhead is better idea. Now, we have newly introduced static_vm infrastructure. With it, we don't need to iterate all mapped areas. Instead, we just iterate static mapped areas. It helps to reduce an overhead of finding matched area. And architecture dependency on vmalloc layer is removed, so it will help to maintainability for vmalloc layer.

2013-02-16ARM: 7645/1: ioremap: introduce an infrastructure for static mapped areaJoonsoo Kim
In current implementation, we used ARM-specific flag, that is, VM_ARM_STATIC_MAPPING, for distinguishing ARM specific static mapped area. The purpose of static mapped area is to re-use static mapped area when entire physical address range of the ioremap request can be covered by this area. This implementation causes needless overhead for some cases. For example, assume that there is only one static mapped area and vmlist has 300 areas. Every time we call ioremap, we check 300 areas for deciding whether it is matched or not. Moreover, even if there is no static mapped area and vmlist has 300 areas, every time we call ioremap, we check 300 areas in now. If we construct a extra list for static mapped area, we can eliminate above mentioned overhead. With a extra list, if there is one static mapped area, we just check only one area and proceed next operation quickly. In fact, it is not a critical problem, because ioremap is not frequently used. But reducing overhead is better idea. Another reason for doing this work is for removing architecture dependency on vmalloc layer. I think that vmlist and vmlist_lock is internal data structure for vmalloc layer. Some codes for debugging and stat inevitably use vmlist and vmlist_lock. But it is preferable that they are used as least as possible in outside of vmalloc.c Now, I introduce an ARM-specific infrastructure for static mapped area. In the following patch, we will use this and resolve above mentioned problem.
