eb323b075a tipc: Optimize termination of configuration service
Termination no longer tests to see if the configuration service
port was successfully created or not. In the unlikely event that the
port was not created, attempting to delete the non-existent port is
detected gracefully and causes no harm.

861d3a0e5b tipc: Optimize initialization of configuration service
Initialization now occurs in the calling thread of control,
rather than being deferred to the TIPC tasklet.  With the
current codebase, the deferral is no longer necessary.

a2cfd45b52 tipc: Optimize re-initialization of configuration service
Streamlines the job of re-initializing TIPC's configuration service
when a node's network address is first assigned. Rather than destroying
the configuration server port and then recreating it, TIPC now simply
withdraws the existing {0,<0.0.0>} name publication and creates a new
{0,<Z.C.N>} name publication that identifies the node's network address
to interested subscribers.

fa83af7e8f blackfin: fix ifdef fustercluck in mach-bf538/boards/ezkit.c
This file has lots and lots of ifdef, around structure decls
and structure usages.  The failure issue was that we would
build the BF538-EZKIT_defconfig and get:

 arch/blackfin/mach-bf538/boards/ezkit.c:924:3: error: 'bfin_lq035q1_device'
 undeclared here (not in a function)

even though the same ifdef _appeared_ to enable both the struct
declaration and the code that used it.  Yet cpp was telling us we
didn't have the struct, but we still had the usage of it.

However, _appeared_ is the operative word.  After marking all the
anonymous #endif with their parent #ifdef config options, it was
_then_ clear that there was a misplaced #endif that was hiding
the struct declaration.

The real guts of the patch boils down to this:

-#endif
+#endif /* CONFIG_MTD_M25P80 */
+#endif /* CONFIG_SPI_BFIN5XX */
 [...]
-#endif  /* spi master and devices */

but since I had to tag the #endif with their respective #ifdef
options to find this misplaced SPI endif, it would be silly to
then go and delete them all.  So they stay.

6651819b4b drm/i915: handle input/output sdvo timings separately in mode_set
We seem to have a decent confusion between the output timings and the
input timings of the sdvo encoder. If I understand the code correctly,
we use the original mode unchanged for the output timings, safe for
the lvds case. And we should use the adjusted mode for input timings.

Clarify the situation by adding an explicit output_dtd to the sdvo
mode_set function and streamline the code-flow by moving the input and
output mode setting in the sdvo encode together.

Furthermore testing showed that the sdvo input timing needs the
unadjusted dotclock, the sdvo chip will automatically compute the
required pixel multiplier to get a dotclock above 100 MHz.

Fix this up when converting a drm mode to an sdvo dtd.

This regression was introduced in

     /* If it's a TV, we already set the output timing in mode_fixup.
      * Otherwise, the output timing is equal to the input timing.

Due to questions raised in review, below a more elaborate analysis of
the bug at hand:

Sdvo seems to have two timings, one is the output timing which will be
sent over whatever is connected on the other side of the sdvo chip (panel,
hdmi screen, tv), the other is the input timing which will be generated by
the gmch pipe. It looks like sdvo is expected to scale between the two.

To make things slightly more complicated, we have a bunch of special
cases:
- For lvds panel we always use a fixed output timing, namely
  intel_sdvo->sdvo_lvds_fixed_mode, hence that special case.
- Sdvo has an interface to generate a preferred input timing for a given
  output timing. This is the confusing thing that I've tried to clear up
  with the follow-on patches.
- A special requirement is that the input pixel clock needs to be between
  100MHz and 200MHz (likely to keep it within the electromechanical design
  range of PCIe), 270MHz on later gen4+. Lower pixel clocks are
  doubled/quadrupled.

The thing this patch tries to fix is that the pipe needs to be
explicitly instructed to double/quadruple the pixels and needs the
correspondingly higher pixel clock, whereas the sdvo adaptor seems to
do that itself and needs the unadjusted pixel clock. For the sdvo
encode side we already set the pixel mutliplier with a different
command (0x21).

This patch tries to fix this mess by:
- Keeping the output mode timing in the unadjusted plain mode, safe
  for the lvds case.
- Storing the input timing in the adjusted_mode with the adjusted
  pixel clock. This way we don't need to frob around with the core
  crtc mode set code.
- Fixing up the pixelclock when constructing the sdvo dtd timing
  struct. This is why the first hunk of the patch is an integral part
  of the series.
- Dropping the is_tv special case because input_dtd is equivalent to
  adjusted_mode after these changes. Follow-up patches clear this up
  further (by simply ripping out intel_sdvo->input_dtd because it's
  not needed).

724b6daa13 perf: Fix perf_event_for_each() to use sibling
In perf_event_for_each() we call a function on an event, and then
iterate over the siblings of the event.

However we don't call the function on the siblings, we call it
repeatedly on the original event - it seems "obvious" that we should
be calling it with sibling as the argument.

It looks like this broke in commit 75f937f24b ("Fix ctx->mutex
vs counter->mutex inversion").

The only effect of the bug is that the PERF_IOC_FLAG_GROUP parameter
to the ioctls doesn't work.

eb95308ee2 sched: Fix more load-balancing fallout
Commits 367456c756 ("sched: Ditch per cgroup task lists for
load-balancing") and 5d6523ebd ("sched: Fix load-balance wreckage")
left some more wreckage.

By setting loop_max unconditionally to ->nr_running load-balancing
could take a lot of time on very long runqueues (hackbench!). So keep
the sysctl as max limit of the amount of tasks we'll iterate.

Furthermore, the min load filter for migration completely fails with
cgroups since inequality in per-cpu state can easily lead to such
small loads :/

Furthermore the change to add new tasks to the tail of the queue
instead of the head seems to have some effect.. not quite sure I
understand why.

Combined these fixes solve the huge hackbench regression reported by
Tim when hackbench is ran in a cgroup.

1bb57e940e dl2k: Clean up rio_ioctl
The dl2k driver's rio_ioctl call has a few issues:
- No permissions checking
- Implements SIOCGMIIREG and SIOCGMIIREG using the SIOCDEVPRIVATE numbers
- Has a few ioctls that may have been used for debugging at one point
  but have no place in the kernel proper.

This patch removes all but the MII ioctls, renumbers them to use the
standard ones, and adds the proper permission check for SIOCSMIIREG.

We can also get rid of the dl2k-specific struct mii_data in favor of
the generic struct mii_ioctl_data.

Since we have the phyid on hand, we can add the SIOCGMIIPHY ioctl too.

Most of the MII code for the driver could probably be converted to use
the generic MII library but I don't have a device to test the results.

still respect the multicast settings and not simply exit after setting

319d013af0 atl1c: add function atl1c_power_saving
This function is used for suspend of S1/S3/S4 and driver remove.
It sets MAC/PHY based on the WoL configuation to get lower power
consumption.
atl1c_phy_power_saving is renamed to atl1c_phy_to_ps_link, this
function is just make PHY enter a link/speed mode to eat less
power.
REG_MAC_CTRL register is refined as well.

ce5b972bc8 atl1c: update PHY reset related routine
Many magic data are re-configured for PHY during its reset operation
based on chip type to get better compability and stability.
REG_PHY_CTRL register may be configured by BIOS before enter OS.
so, the driver can't directly write to it without any Read-Op.
this change also affect suspend and phy_disable routines.
PHY debug ports and extension registers are refined as well.

7737fd9645 atl1c: refine SERDES-clock related code
bit 17/18 of reg1424 must be clear for l2cb 1.x, or it will cause
the write-reg operation fail without cable connected.
so, please do connect the cable when apply this patch to the driver
to make sure these 2bits are cleared by new driver.
The revised code is move to al1c_reset_mac.
SERDES register definition is refined as well.

when do reset MAC, speed/duplex control right should be transferred
to software before do PHY auto-neg -- by bit MASTER_CTRL_SPEED_MODE_SW.
SERDES register definition is refined as well.

phy register is read/write via MDIO control module ---
that module will be affected by the hibernate status,
to access phy regs in hib stutus, slow frequency clk must
be selected.
To access phy extension register, the MDIO related
registers are refined/updated, a _core function is
re-wroted for both regular PHY regs and extension regs.
existing PHY r/w function is revised based on the _core.
PHY extension registers will be used for the comming
patches.

MCC Response CQEs are processed as part of NAPI poll routine and
also synchronously. If MCC completions are consumed by NAPI poll
routine, wrong status is returned to synchronously waiting routine.
Fix this by getting status of MCC command from command response
instead of response CQEs.

af311fe310 be2net: Fix traffic stall INTx mode
EQ is getting armed wrongly in INTx mode as INTx interrupt is taking
some time to deassert. This can cause another interrupt while NAPI is
scheduled and scheduling a NAPI in interrupt does not take effect.
This causes interrupt to be missed and traffic stalls. Fixing this by
preventing wrong arming of EQ.
