c167a6fc6e drm/i915: merge gmbus and gpio i2c adpater into one
... and directly call the newly exported i2c bit-banging functions.

The code is still pretty convoluted because we only set up the gpio
i2c stuff when actually falling back, resulting in more complexity
than necessary. This will be fixed up in the next patch.

v2: Use exported i2c_bit_algo vtable instead of exported functions.

36c785f051 drm/i915: merge struct intel_gpio into struct intel_gmbus
When we set up the gpio fallback, we always have a 1:1 relationship
with an intel_gmbus. Exploit that to store all gpio related data in
there, too. This is a preparation step to merge the tw i2c adapters
controlling the same bus into one.

Just mundane code-munging in this patch.

b0209b3995 i2c: export bit-banging algo functions
i915 has a hw i2c controller (gmbus) but for a bunch of stupid reasons
we need to be able to fall back to the bit-banging algo on gpio pins.

The current code sets up a 2nd i2c controller for the same i2c bus using
the bit-banging algo. This has a bunch of issues, the major one being
that userspace can directly access this fallback i2c adaptor behind
the drivers back.

But we need to frob a few registers before and after using fallback
gpio bit-banging, so this horribly fails.

The new plan is to only set up one i2c adaptor and transparently fall
back to bit-banging by directly calling the xfer function of the bit-
banging algo in the i2c core.

To make that possible, export the 2 i2c algo functions.

v2: As suggested by Jean Delvare, simply export the i2c_bit_algo
vtable instead of the individual functions.

I'd like to export the corresponding functions from the i2c core

caae745a35 drm/i915: Fix single msg gmbus_xfers writes
gmbus_xfer with a single message (particularly a single message write) would
set Bus Cycle Select to 100b, the Gen Stop cycle, instead of 101b,
No Index, Stop cycle. This would not start single message i2c transactions.

Also, gmbus_xfer done: will disable the interface without checking if
it is idle. In the case of writes, there will be no wait on status or delay
to ensure the write starts and completes before the interface is turned off.

Fixed the former issue by using the same cycle selection as used in the
I2C_M_RD for the write case.
GMBUS_CYCLE_WAIT | (i + 1 == num ? GMBUS_CYCLE_STOP : 0)
Fixed the latter by waiting on GMBUS_ACTIVE to deassert before disable.

Note from the grumpy d-i-n maintainer: The first hunk that changes the
gmbus read path is just cosmetics to align the code with the write
path.  I.e. the commit message above is slightly lying because the
first issue is _only_ with writes (and not simply "particularly").

65ec698d13 tg3: Fix tg3_get_stats64 for 5700 / 5701 devs
tg3_get_stats64() takes tp->lock when dealing with non-serdes bcm5700
and bcm5701 devices.  However, functions that call tg3_halt() have
already acquired tp->lock.  When tg3_get_stats64() is called in
tg3_halt(), deadlock will occur.

This patch fixes the problem by separating the stat gathering code into
a new tg3_get_nstats() function.  tg3_get_stats64() is recoded to call
this function and take tp->lock.  The code that takes tp->lock in
tg3_calc_crc_errors() has been removed.  Function signatures have been
cleaned up too.

IEEE80211_TX_CTL_CLEAR_PS_FILT) which are set on
frames that should be sent although the receiving
station is still in powersave mode.

992d52529d carl9170: Fix memory accounting when sta is in power-save mode.
On Access Point mode, when transmitting a packet, if the destination
station is in powersave mode, we abort transmitting the packet to the
device queue, but we do not reclaim the allocated memory.  Given enough
packets, we can go in a state where there is no packet on the device
queue, but we think the device has no memory left, so no packet gets
transmitted, connections breaks and the AP stops working.

This undo the allocation done in the TX path when the station is in
power-save mode.

3868137ea4 ALSA: hda - Add a fake mute feature
Some codecs don't supply the mute amp-capabilities although the lowest
volume gives the mute.  It'd be handy if the parser provides the mute
mixers in such a case.

This patch adds an extension amp-cap bit (which is used only in the
driver) to represent the min volume = mute state.  Also modified the
amp cache code to support the fake mute feature when this bit is set
but the real mute bit is unset.

In addition, conexant cx5051 parser uses this new feature to implement
the missing mute controls.

81ffbbedc3 drm/radeon: fix deferred page-flip detection logic on Avivo-based ASICs
This fixes page-flip-related flickering observed on Iconia Tab W500.

The update_pending status returned by radeon_page_flip is very accurate on
Avivo-based ASICs when vpos is negative.

Experiments were conducted on several ASIC generations ranging from RS690
to Cayman where the page flip was artificially timed to occur at a specific
vpos. With negative vpos, overriding update_pending always lead to
flickering.

The same experiment on RV380 and RV410 showed that update_pending is not
accurate with negative vpos. In most cases update_pending == 1 is returned
although the flip would complete before the start of the next frame.
Therefore I left the behaviour unchanged for pre-AVIVO ASICs for
performance reasons, although this may result in flickering in rare cases.

This change also makes the logic a little easier to understand.

5a3ff8473c ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts
The following commit: 2f31b51659
Author: Tero Kristo <t-kristo@ti.com>
Date:   Fri Dec 16 14:37:00 2011 -0700

    ARM: OMAP4: PRM: use PRCM interrupt handler

introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:

[    0.208221] PRCM: failed to allocate irq descs: -12

Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.

[    1.802795] mux: Failed to setup hwmod io irq -22

Fix that by adding 64 more interrupts for OMAP2PLUS config.

4c90d3b303 tcp: fix false reordering signal in tcp_shifted_skb
When tcp_shifted_skb() shifts bytes from the skb that is currently
pointed to by 'highest_sack' then the increment of
TCP_SKB_CB(skb)->seq implicitly advances tcp_highest_sack_seq(). This
implicit advancement, combined with the recent fix to pass the correct
SACKed range into tcp_sacktag_one(), caused tcp_sacktag_one() to think
that the newly SACKed range was before the tcp_highest_sack_seq(),
leading to a call to tcp_update_reordering() with a degree of
reordering matching the size of the newly SACKed range (typically just
1 packet, which is a NOP, but potentially larger).

This commit fixes this by simply calling tcp_sacktag_one() before the
TCP_SKB_CB(skb)->seq advancement that can advance our notion of the
highest SACKed sequence.

Correspondingly, we can simplify the code a little now that
tcp_shifted_skb() should update the lost_cnt_hint in all cases where
skb == tp->lost_skb_hint.

ecb9719236 tcp: fix comment for tp->highest_sack
There was an off-by-one error in the comments describing the
highest_sack field in struct tcp_sock. The comments previously claimed
that it was the "start sequence of the highest skb with SACKed
bit". This commit fixes the comments to note that it is the "start
sequence of the skb just *after* the highest skb with SACKed bit".

8411371709 x86/PCI: use host bridge _CRS info on MSI MS-7253
In the spirit of commit 29cf7a30f8 ("x86/PCI: use host bridge _CRS
info on ASUS M2V-MX SE"), this DMI quirk turns on "pci_use_crs" by
default on a board that needs it.

This fixes boot failures and oopses introduced in 3e3da00c01
("x86/pci: AMD one chain system to use pci read out res").  The quirk
is quite targetted (to a specific board and BIOS version) for two
reasons:

 (1) to emphasize that this method of tackling the problem one quirk
     at a time is a little insane

 (2) to give BIOS vendors an opportunity to use simpler tables and
     allow us to return to generic behavior (whatever that happens to
     be) with a later BIOS update

In other words, I am not at all happy with having quirks like this.
But it is even worse for the kernel not to work out of the box on
these machines, so...

d5a74afd08 IOMMU fixes for Linux 3.3-rc5
All the fixes are for the OMAP IOMMU driver. The first patch is the
 biggest one. It fixes the calls of the function omap_find_iovm_area() in
 the omap-iommu-debug module which expects a 'struct device' parameter
 since commit fabdbca instead of an omap_iommu handle. The
 omap-iommu-debug code still passed the handle to the function which
 caused a crash.
 The second patch fixes a NULL pointer dereference in the OMAP code and
 the third patch makes sure that the omap-iommu is initialized before the
 omap-isp driver, which relies on the iommu. The last patch is only a
 workaround until defered probing is implemented.

78d3e00bb0 watchdog: fix error in probe() of s3c2410_wdt (reset at booting)
Probe function of s3c2410 watchdog calls request_irq before initializing
required value (wdt_count). This incurs resetting watchdog counter value
and watchdog-reboot during booting up.

This patch addresses such an issue by calling request_irq later.

Error handling in probe function and calling oder in remove function are
also revised accordingly.
