cpufreq: s3c24xx: fix "depends on ARM_S3C24XX" in Kconfig

Kconfig symbol S3C24XX_PLL depends on ARM_S3C24XX.  But that symbol
doesn't exist.  Commit f023f8dd59bf ("cpufreq: s3c24xx: move cpufreq
driver to drivers/cpufreq"), which added this issue, makes it clear
that ARM_S3C24XX_CPUFREQ was intended here.

ipv4: set transport header earlier

commit 45f00f99d6e ("ipv4: tcp: clean up tcp_v4_early_demux()") added a
performance regression for non GRO traffic, basically disabling
IP early demux.

IPv6 stack resets transport header in ip6_rcv() before calling
IP early demux in ip6_rcv_finish(), while IPv4 does this only in
ip_local_deliver_finish(), _after_ IP early demux.

GRO traffic happened to enable IP early demux because transport header
is also set in inet_gro_receive()

Instead of reverting the faulty commit, we can make IPv4/IPv6 behave the
same : transport_header should be set in ip_rcv() instead of
ip_local_deliver_finish()

ip_local_deliver_finish() can also use skb_network_header_len() which is
faster than ip_hdrlen()

cpufreq: Revert commit 2f7021a8 to fix CPU hotplug regression

commit 2f7021a8 "cpufreq: protect 'policy->cpus' from offlining
during __gov_queue_work()" caused a regression in CPU hotplug,
because it lead to a deadlock between cpufreq governor worker thread
and the CPU hotplug writer task.

[   60.280582] smpboot: CPU 1 is now offline

The intention of that commit was to avoid warnings during CPU
hotplug, which indicated that offline CPUs were getting IPIs from the
cpufreq governor's work items.  But the real root-cause of that
problem was commit a66b2e5 (cpufreq: Preserve sysfs files across
suspend/resume) because it totally skipped all the cpufreq callbacks
during CPU hotplug in the suspend/resume path, and hence it never
actually shut down the cpufreq governor's worker threads during CPU
offline in the suspend/resume path.

Reflecting back, the reason why we never suspected that commit as the
root-cause earlier, was that the original issue was reported with
just the halt command and nobody had brought in suspend/resume to the
equation.

The reason for _that_ in turn, as it turns out, is that earlier
halt/shutdown was being done by disabling non-boot CPUs while tasks
were frozen, just like suspend/resume....  but commit cf7df378a
(reboot: migrate shutdown/reboot to boot cpu) which came somewhere
along that very same time changed that logic: shutdown/halt no longer
takes CPUs offline.  Thus, the test-cases for reproducing the bug
were vastly different and thus we went totally off the trail.

Overall, it was one hell of a confusion with so many commits
affecting each other and also affecting the symptoms of the problems
in subtle ways.  Finally, now since the original problematic commit
(a66b2e5) has been completely reverted, revert this intermediate fix
too (2f7021a8), to fix the CPU hotplug deadlock.  Phew!

x86: Make sure IDT is page aligned

Since the IDT is referenced from a fixmap, make sure it is page aligned.
Merge with 32-bit one, since it was already aligned to deal with F00F
bug. Since bss is cleared before IDT setup, it can live there. This also
moves the other *_idt_table variables into common locations.

This avoids the risk of the IDT ever being moved in the bss and having
the mapping be offset, resulting in calling incorrect handlers. In the
current upstream kernel this is not a manifested bug, but heavily patched
kernels (such as those using the PaX patch series) did encounter this bug.

The tables other than idt_table technically do not need to be page
aligned, at least not at the current time, but using a common
declaration avoids mistakes.  On 64 bits the table is exactly one page
long, anyway.

USB: move the definition of USB_MAXCHILDREN

The USB_MAXCHILDREN symbol is used in include/uapi/linux/usb/ch11.h, a
user-mode header, even though it is defined in include/linux/usb.h,
which is kernel-only.  This causes compile-time errors when user
programs try to #include linux/usb/ch11.h.

This patch fixes the problem by moving the definition of USB_MAXCHILDREN
into ch11.h.  It also gets rid of unneeded parentheses.

USB: global suspend and remote wakeup don't mix

The hub driver was recently changed to use "global" suspend for system
suspend transitions on non-SuperSpeed buses.  This means that we don't
suspend devices individually by setting the suspend feature on the
upstream hub port; instead devices all go into suspend automatically
when the root hub stops transmitting packets.  The idea was to save
time and to avoid certain kinds of wakeup races.

Now it turns out that many hubs are buggy; they don't relay wakeup
requests from a downstream port to their upstream port if the
downstream port's suspend feature is not set (depending on the speed
of the downstream port, whether or not the hub is enabled for remote
wakeup, and possibly other factors).

We can't have hubs dropping wakeup requests.  Therefore this patch
goes partway back to the old policy: It sets the suspend feature for a
port if the device attached to that port or any of its descendants is
enabled for wakeup.  People will still be able to benefit from the
time savings if they don't care about wakeup and leave it disabled on
all their devices.

In order to accomplish this, the patch adds a new field to the usb_hub
structure: wakeup_enabled_descendants is a count of how many devices
below a suspended hub are enabled for remote wakeup.  A corresponding
new subroutine determines the number of wakeup-enabled devices at or
below an arbitrary suspended USB device.

This should be applied to the 3.10 stable kernel.

One feature latecomer, I've forgotten to merge the patch to reeanble the
Haswell power well feature now that the audio interaction is fixed up.
Since that was the only unfixed issue with it I've figured I could throw
it in a bit late, and it's trivial to revert in case I'm wrong.

Otherwise all bug/regression fixes:
- Fix status page reinit after gpu hangs, spotted by more paranoid igt
  checks.
- Fix object list walking fumble regression in the shrinker (only the
  counting part, the actual shrinking code was correct so no Oops
  potential), from Xiong Zhang.
- Fix DP 1.2 bw limits (Imre).
- Restore legacy forcewake on ivb, too many broken biosen out there. We
  dump a warn though that recent userspace might fall over with that
  config (Guenter Roeck).
- Patch up the gen2 cs tlb w/a.
- Improve the fence coherency w/a now that we have a better understanding
  what's going on. The removed wbinvd+ipi should make -rt folks happy. Big
  thanks to Jon Bloomfield for figuring this out, patches from Chris.
- Fix write-read race when switching ring (Chris). Spotted with code
  inspection, but now we also have an igt for it.

There's an ugly regression we're still working on introduced between
3.10-rc7 and 3.10.0. Unfortunately we can't just revert the offender since
that one fixes another regression :( I've asked Steven to include my
-fixes branch into linux-next to prevent such fallout in the future,
hopefully.

Hey Jens - I've been busy torture testing and chasing bugs, here's the
fruits of my labors. These are all fairly small fixes, some of them
quite important.
linked-list: Remove __list_for_each

__list_for_each used to be the non prefetch() aware list walking
primitive.  When we removed the prefetch macros from the list routines,
it became redundant.  Given it does exactly the same thing as
list_for_each now, we might as well remove it and call list_for_each
directly.

All users of __list_for_each have been converted to list_for_each calls
in the current merge window.

staging: csr: remove driver

This driver is not being updated as the specifications are not able to
be gotten from CSR or anyone else.  Without those, getting this driver
into proper mergable shape is going to be impossible.  So remove the
driver from the tree.

If the specifications ever become available, this patch can be reverted
and the driver fixed up properly.

The first round of IIO fixes for the 3.11 cycle.

This set is larger than I would like, partly due to my lack of review
time in the weeks before the merge window and partly because a
couple of large drivers and the subsystem as a whole seem to be
getting a lot more exposure and testing recently.

1) A long term bug in trigger handling gave a double free of the device.

2) Wrong return value handling means offsets are ignored in
   iio_convert_raw_to_processed_unlocked.

3) The iio_channel_has_info utility function was incorrectly updated
   during the recent info_mask split, this is now fixed.

4) mxs-lradc has a couple of little fixes.

5) A couple of missing .driver_module entries meant that drivers
   could be removed from underneath their users.

6) Error path fixes for ad7303 and lis3l02dq.

7) The scale value for presure in the lps331ap driver was out by
   a factor of 100.

hyperv: Fix the NETIF_F_SG flag setting in netvsc

SG mode is not currently supported by netvsc, so remove this flag for now.
Otherwise, it will be unconditionally enabled by commit ec5f0615642
    "Kill link between CSUM and SG features"
Previously, the SG feature is disabled because CSUM is not set here.

Drivers: hv: vmbus: incorrect device name is printed when child device is unregistered

Whenever a device is unregistered in vmbus_device_unregister (drivers/hv/vmbus_drv.c), the device name in the log message may contain garbage as the memory has already been freed by the time pr_info is called. Log example:
 [ 3149.170475] hv_vmbus: child device àõsèè0_5 unregistered

By logging the message just before calling device_unregister, the correct device name is printed:
[ 3145.034652] hv_vmbus: child device vmbus_0_5 unregistered

Also changing register & unregister messages to debug to avoid unnecessarily cluttering the kernel log.
