 "Bug fixes galore, mostly in drivers as is often the case:

  1) USB gadget and cdc_eem drivers need adjustments to their frame size
     lengths in order to handle VLANs correctly.  From Ian Coolidge.

  2) TIPC and several network drivers erroneously call tasklet_disable
     before tasklet_kill, fix from Xiaotian Feng.

  3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
     fix from Cyril Brulebois.

  4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
     Nathan Walp.

  5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
     zero.  From John Fastabend.

  6) Fix smsc95xx tx checksum offload on big-endian, from Steve
     Glendinning.

  7) __inet_diag_dump() needs to repsect and report the error value
     returned from inet_diag_lock_handler() rather than ignore it.
     Otherwise if an inet diag handler is not available for a particular
     protocol, we essentially report success instead of giving an error
     indication.  Fix from Cyrill Gorcunov.

  8) When the QFQ packet scheduler sees TSO/GSO packets it does not
     handle things properly, and in fact ends up corrupting it's
     datastructures as well as mis-schedule packets.  Fix from Paolo
     Valente.

  9) Fix oopser in skb_loop_sk(), from Eric Leblond.

  10) CXGB4 passes partially uninitialized datastructures in to FW
      commands, fix from Vipul Pandya.

  11) When we send unsolicited ipv6 neighbour advertisements, we should
      send them to the link-local allnodes multicast address, as per
      RFC4861.  Fix from Hannes Frederic Sowa.

  12) There is some kind of bug in the usbnet's kevent deferral
      mechanism, but more immediately when it triggers an uncontrolled
      stream of kernel messages spam the log.  Rate limit the error log
      message triggered when this problem occurs, as sending thousands
      of error messages into the kernel log doesn't help matters at all,
      and in fact makes further diagnosis more difficult.

      From Steve Glendinning.

  13) Fix gianfar restore from hibernation, from Wang Dongsheng.

  14) The netlink message attribute sizes are wrong in the ipv6 GRE

add empty static inlines for !CONFIG_OF". Contrary to that commit title, the

Wang Dongsheng [Fri, 9 Nov 2012 04:43:51 +0000 (04:43 +0000)]
gianfar: ethernet vanishes after restoring from hibernation

If a gianfar ethernet device is down prior to hibernating a
system, it will no longer be present upon system restore.

For example:

~# ifconfig eth0 down
~# echo disk > /sys/power/state

  <trigger a restore from hibernation>

~# ifconfig eth0 up
SIOCSIFFLAGS: No such device

This happens because the restore function bails out early upon
finding devices that were not up at hibernation.  In doing so,
it never gets to the netif_device_attach call at the end of
the restore function.  Adding the netif_device_attach as done
here also makes the gfar_restore code consistent with what is
done in the gfar_resume code.

12 years agoARM: PMU: fix runtime PM enable
Jon Hunter [Thu, 25 Oct 2012 20:23:18 +0000 (21:23 +0100)]
ARM: PMU: fix runtime PM enable

Commit 7be2958 (ARM: PMU: Add runtime PM Support) updated the ARM PMU code to
use runtime PM which was prototyped and validated on the OMAP devices. In this
commit, there is no call pm_runtime_enable() and for OMAP devices
pm_runtime_enable() is currently being called from the OMAP PMU code when the
PMU device is created. However, there are two problems with this:

1. For any other ARM device wishing to use runtime PM for PMU they will need
   to call pm_runtime_enable() for runtime PM to work.
2. When booting with device-tree and using device-tree to create the PMU
   device, pm_runtime_enable() needs to be called from within the ARM PERF
   driver as we are no longer calling any device specific code to create the
   device. Hence, PMU does not work on OMAP devices that use the runtime PM
   callbacks when using device-tree to create the PMU device.

Therefore,  call pm_runtime_enable() directly from the ARM PMU driver when
registering the device. For platforms that do not use runtime PM,
pm_runtime_enable() does nothing and for platforms that do use runtime PM but
may not require it specifically for PMU, this will just add a little overhead
when initialising and uninitialising the PMU device.

Tested with PERF on OMAP2420, OMAP3430 and OMAP4460.
