88de3d0d71 arm-soc: bug fixes for v3.6-rc2
These are a bunch of bug fixes that came in after the merge window and
 one update for the MAINTAINERS file. The largest part of the fixes
 are patches that address bugs found by building all the ARM defconfig
 files. There are a lot more warnings that we have patches for, but
 the others are either still under discussion or are harmless and
 do not cause actual problems besides making the build slightly noisy.

bb1a5805ed usb/ohci-omap: remove unused variable
Commit c2e935a7d "USB: move transceiver from ehci_hcd and ohci_hcd to
hcd and rename it as phy" removed the last use of the "ohci" variable
in the usb_hcd_omap_remove function, but left the variable in place
unused.

Without this patch, building omap1_defconfig results in:

In file included from drivers/usb/host/ohci-hcd.c:1013:0:
drivers/usb/host/ohci-omap.c: In function 'usb_hcd_omap_remove':

  dealt with - the series by Fernando conflicts a lot with Jan's, breaks
  userland ABI (FIFREEZE semantics gets changed) and trades the deadlock

0614002bb5 netvm: propagate page->pfmemalloc from skb_alloc_page to skb
The skb->pfmemalloc flag gets set to true iff during the slab allocation
of data in __alloc_skb that the the PFMEMALLOC reserves were used.  If
page splitting is used, it is possible that pages will be allocated from
the PFMEMALLOC reserve without propagating this information to the skb.
This patch propagates page->pfmemalloc from pages allocated for fragments
to the skb.

It works by reintroducing and expanding the skb_alloc_page() API to take
an skb.  If the page was allocated from pfmemalloc reserves, it is
automatically copied.  If the driver allocates the page before the skb, it
should call skb_propagate_pfmemalloc() after the skb is allocated to
ensure the flag is copied properly.

Failure to do so is not critical.  The resulting driver may perform slower
if it is used for swap-over-NBD or swap-over-NFS but it should not result
in failure.

f96a4216e8 USB: echi-dbgp: increase the controller wait time to come out of halt.
The default 10 microsecond delay for the controller to come out of
halt in dbgp_ehci_startup is too short, so increase it to 1 millisecond.

This is based on emperical testing on various USB debug ports on
modern machines such as a Lenovo X220i and an Ivybridge development
platform that needed to wait ~450-950 microseconds.

Pull MFD bits from Samuel Ortiz:
 "We have support for a few new drivers:
   - Samsung s2mps11
   - Wolfson Microelectronics wm5102 and wm5110
   - Marvell 88PM800 and 88PM805
   - TI twl6041

  We also have our regular driver improvements:
   - Device tree and IRQ domain support for STE AB8500
   - Regmap and devm_* API conversion for TI tps6586x
   - Device tree support for Samsung max77686
   - devm_* API conversion for STE AB3100

  Besides that, quite a lot of fixing and cleanup for mc13xxx, tps65910,
  tps65090, da9052 and twl-core."

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

The most important feature of this patch set is the new async infrastructure
 that makes sure async_synchronize_full() synchronizes all domains and allows
 us to remove all the hacks (like having scsi_complete_async_scans() in the
 device base code) and means that the async infrastructure will "just work" in
 future. The rest is assorted driver updates (aacraid, bnx2fc, virto-scsi,
 megaraid, bfa, lpfc, qla2xxx, qla4xxx) plus a lot of infrastructure work in

3c4cfadef6 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next
Pull networking changes from David S Miller:

 1) Remove the ipv4 routing cache.  Now lookups go directly into the FIB
    trie and use prebuilt routes cached there.

    No more garbage collection, no more rDOS attacks on the routing
    cache.  Instead we now get predictable and consistent performance,
    no matter what the pattern of traffic we service.

    This has been almost 2 years in the making.  Special thanks to
    Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
    have helped along the way.

    I'm sure that with a change of this magnitude there will be some
    kind of fallout, but such things ought the be simple to fix at this
    point.  Luckily I'm not European so I'll be around all of August to
    fix things :-)

    The major stages of this work here are each fronted by a forced
    merge commit whose commit message contains a top-level description
    of the motivations and implementation issues.

 2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
    input.

 3) TCP SYN/ACK performance tweaks from Eric Dumazet.

 4) Add namespace support for netfilter L4 conntrack helpers, from Gao
    Feng.

 5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
    Yuval Mintz.

 6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.

 7) Support for connection tracker helpers in userspace, from Pablo
    Neira Ayuso.

 8) Allow userspace driven TX load balancing functions in TEAM driver,
    from Jiri Pirko.

 9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
    embedded gotos.

10) TCP Small Queues, essentially minimize the amount of TCP data queued
    up in the packet scheduler layer.  Whereas the existing BQL (Byte
    Queue Limits) limits the pkt_sched --> netdevice queuing levels,
    this controls the TCP --> pkt_sched queueing levels.

    From Eric Dumazet.

11) Reduce the number of get_page/put_page ops done on SKB fragments,
    from Alexander Duyck.

12) Implement protection against blind resets in TCP (RFC 5961), from
    Eric Dumazet.

13) Support the client side of TCP Fast Open, basically the ability to
    send data in the SYN exchange, from Yuchung Cheng.

    Basically, the sender queues up data with a sendmsg() call using
    MSG_FASTOPEN, then they do the connect() which emits the queued up
    fastopen data.

14) Avoid all the problems we get into in TCP when timers or PMTU events
    hit a locked socket.  The TCP Small Queues changes added a
    tcp_release_cb() that allows us to queue work up to the
    release_sock() caller, and that's what we use here too.  From Eric
    Dumazet.

15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.

d6dfc868bc target: Allow for target_submit_cmd() returning errors
We want it to be possible for target_submit_cmd() to return errors up
to its fabric module callers.  For now just update the prototype to
return an int, and update all callers to handle non-zero return values
as an error.

This is immediately useful for tcm_qla2xxx to fix a long-standing active
I/O session shutdown race, but tcm_fc, usb-gadget, and sbp-target the
fabric maintainers need to check + ACK that handling a target_submit_cmd()
failure due to session shutdown does not introduce regressions

The MC7710 in QMI mode does not support the vendor
specific USB requests used by this driver.  The most
noticable effect of this is a 5 second delay as each
serial port is probed, caused by the set_power_state
command timing out:

 [   17.434291] usbcore: registered new interface driver sierra

The MC7710 provide the same Qualcomm serial interfaces
as Gobi modules, and the qcserial driver has been extended
to support the module instead of this driver.

1937131a01 USB: qcserial: adding Sierra Wireless devices
The QMI mode of the Sierra Wireless MC7710 is close to
a Gobi device, and also identified as one by the
Windows drivers provided by Sony.  The serial interfaces
are the same as for any other Gobi module, but the USB
interface layout is different:

 0: DM/DIAG (also present in bootloader mode)
 2: NMEA
 3: AT-capable modem port
 8: QMI/net
 19: QMI/net (not always present)
 20: QMI/net (not always present)

Note in particular that the NMEA and AT ports are reversed
compared to a Gobi 2k+ device, and that the DM port appears
as a QDL port in bootloader mode using the same device ID.

The Sony driver also document two new devices with standard
Gobi 2k+ layout (1199:68a5, 1199:68a9) having a QDL mode
(1199:68a4, 1199:68a8).  Adding these as well.

Lenovo Windows drivers document the USB interface layout
for a few additional Sierra Wireless devices. Adding these
while at it:
- MC7770 (1199:901b) with standard Gobi 2k+ layout
- MC7700 (0f3d:68a2) with the same layout as MC7710
- MC7750 (114f:68a2) with the same layout as MC7710
- EM7700 (1199:901c) with the same layout as MC7710
