Pull MMC fixes from Chris Ball:
- Disable use of MSI in sdhci-pci, which caused multiple chipsets to
stop working in 3.4-rc1. I'll wait to turn this on again until we
have a chipset whitelist for it.
- Fix a libertas SDIO powered-resume regression introduced in 3.3;
thanks to Neil Brown and Rafael Wysocki for this fix.
- Fix module reloading on omap_hsmmc.
- Stop trusting the spec/card's specified maximum data timeout length,
and use three seconds instead. Previously we used 300ms.
Also cleanups and fixes for s3c, atmel, sh_mmcif and omap_hsmmc.

Several people have noticed that crappy SD cards take much longer to
complete multiple block writes than the 300ms that Linux specifies.
Try to work around this by using a three second write timeout instead.
This is a generalized version of a patch from Chase Maupin
<Chase.Maupin@ti.com>, whose patch description said:
* With certain SD cards timeouts like the following have been seen
due to an improper calculation of the dto value:
mmcblk0: error -110 transferring data, sector 4126233, nr 8,
card status 0xc00
* By removing the dto calculation and setting the timeout value
to the maximum specified by the SD card specification part A2
section 2.2.15 these timeouts can be avoided.
* This change has been used by beagleboard users as well as the
Texas Instruments SDK without a negative impact.
* There are multiple discussion threads about this but the most
relevant ones are:
* http://talk.maemo.org/showthread.php?p=1000707#post1000707
* http://www.mail-archive.com/linux-omap@vger.kernel.org/msg42213.html
* Original proposal for this fix was done by Sukumar Ghoral of
Texas Instruments
* Tested using a Texas Instruments AM335x EVM

The driver should not try to switch to 1.8V when the SD 3.0 host
controller does not have any UHS capabilities bits set (SDR50, DDR50
or SDR104). See page 72 of "SD Specifications Part A2 SD Host
Controller Simplified Specification Version 3.00" under
"1.8V Signaling Enable". Instead of setting SDR12 and SDR25 in the host
capabilities data structure for all V3.0 host controllers, only set them
if SDR104, SDR50 or DDR50 is set in the host capabilities register. This
will prevent the switch to 1.8V later.

This reverts commit e6039832bed9a9b967796d7021f17f25b625b616.
There are reports of MSI breaking SDHCI on multiple chipsets (JMicron
and O2Micro, at least), so this should be reverted until we come up
with a whitelist or something.

mmc_select_powerclass() function returns error if eMMC
VDD level supported by host is between 2.7v to 3.2v.
According to eMMC specification, valid voltage for high
voltage cards is 2.7v to 3.6v. This patch ensures that
2.7v to 3.6v VDD range is treated as valid range.
Also, failure to set the power class shouldn't be treated
as fatal error because even if setting the power class
fails, card can still work in default power class.
If mmc_select_powerclass() returns error, just print
the warning message and go ahead with rest of the card
initialization.

OMAP4 and OMAP3 HSMMC IP registers differ by 0x100 offset.
Adding the offset to platform_device resource structure
increments the start address for every insmod operation.
MMC command fails on re-insertion as module due to incorrect register
base. Fix this by updating the ioremap base address only.

Neil Brown reports that commit 35cd133c
PM: Run the driver callback directly if the subsystem one is not there
breaks suspend for his libertas wifi, because SDIO has a protocol
where the suspend method can return -ENOSYS and this means "There is
no point in suspending, just turn me off". Moreover, the suspend
methods provided by SDIO drivers are not supposed to be called by
the PM core or bus-level suspend routines (which aren't presend for
SDIO). Instead, when the SDIO core gets to suspend the device's
ancestor, it calls the device driver's suspend function, catches the
ENOSYS, and turns the device off.
The commit above breaks the SDIO core's assumption that the device
drivers' callbacks won't be executed if it doesn't provide any
bus-level callbacks. If fact, however, this assumption has never
been really satisfied, because device class or device type suspend
might very well use the driver's callback even without that commit.
The simplest way to address this problem is to make the SDIO core
tell the PM core to ignore driver callbacks, for example by providing
no-operation suspend/resume callbacks at the bus level for it,
which is implemented by this change.

According to the specifications for SD and (e)MMC default
blocksize (named BLOCKLEN in Spec.) must always be 512
bytes. Since we hardcoded to always use 512 bytes, we do
not explicitly have to set it. Future improvements should
potentially make it possible to use a greater blocksize
than 512 bytes, but until then let's skip this.

The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
By using devm_ioremap, it also removes a potential memory leak, because
there was no call to iounmap in the probe function.
The call to platform_get_resource was moved just to make it closer to the
place where its result it used.

SDHCI controllers on Exynos4 do not include the sdclk divider as per the
sdhci controller specification. This case can be represented using the
sdhci quirk SDHCI_QUIRK_NONSTANDARD_CLOCK instead of using an additional
enum type definition 'clk_types'.
Hence, usage of clk_type member in platform data is removed and the sdhci
quirk is used. In addition to that, since this qurik is SoC specific,
driver data is introduced to represent controllers on SoC's that require
this quirk.

9) Add missing address change event emissions to bonding, from Shlomo

10) /proc/net/dev regressed because it uses a private offset to track

pullback that the seq_file code does resulting in some entries being
missed in large dumps.
Fix from Eric Dumazet.
11) do_tcp_sendpage() unloads the send queue way too fast, because it
invokes tcp_push() when it shouldn't. Let the natural sequence
generated by the splice paths, and the assosciated MSG_MORE
settings, guide the tcp_push() calls.
Otherwise what goes out of TCP is spaghetti and doesn't batch
effectively into GSO/TSO clusters.
From Eric Dumazet.
12) Once we put a SKB into either the netlink receiver's queue or a
socket error queue, it can be consumed and freed up, therefore we
cannot touch it after queueing it like that.
Fixes from Eric Dumazet.
13) PPP has this annoying behavior in that for every transmit call it
immediately stops the TX queue, then calls down into the next layer
to transmit the PPP frame.
But if that next layer can take it immediately, it just un-stops the
TX queue right before returning from the transmit method.
Besides being useless work, it makes several facilities unusable, in
particular things like the equalizers. Well behaved devices should
only stop the TX queue when they really are full, and in PPP's case
when it gets backlogged to the downstream device.
David Woodhouse therefore fixed PPP to not stop the TX queue until
it's downstream can't take data any more.

When a slave comes up, we're unsetting the current_arp_slave without
removing active flags from it, which can lead to situations where we have
more than one slave with active flags in active-backup mode.
To avoid this situation we must remove the active flags from a slave before
removing it as a current_arp_slave.

The driver uses a 2-order allocation, which is too much on architectures
like ppc64, which has a 64KiB page. This particular allocation is used
for large packet fragments that may have a size of 512, 1024, 4096 or
fill the whole allocation. So, a minimum size of 16384 is good enough
and will be the same size that is used in architectures of 4KiB sized
pages.
This will avoid allocation failures that we see when the system is under
stress, but still has plenty of memory, like the one below.
This will also allow us to set the interface MTU to higher values like
9000, which was not possible on ppc64 without this patch.

This patch fixes a link problem on BCM57712 + BCM8727 designs in which the TX
laser is controller by GPIO, after 1.60.xx drivers were previously loaded.
On these designs the TX_LASER is enabled by logic AND between the PHY
(through MDIO), and the GPIO. When an old driver is used, it disables the
MDIO part, hence the GPIO control had no affect de facto.

Modified from original patch from Chris.
The sky2 driver has to have 8 byte alignment of receive buffer
on some chip versions. On architectures which don't support efficient
unaligned access this doesn't work very well. The solution is to
just copy all received packets which is what the driver already
does for small packets.
This allows the driver to be used on the Tilera TILEmpower-Gx, since
the tile architecture doesn't currently handle kernel unaligned accesses,
just userspace.

The current implemenation was buggy for slaves who use ndo_neigh_setup,
since the networking stack invokes the bonding device ndo entry (from
neigh_params_alloc) before any devices are enslaved, and the bonding
driver can't further delegate the call at that point in time. As a
result when bonding IPoIB devices, the neigh_cleanup hasn't been called.
Fix that by deferring the actual call into the slave ndo_neigh_setup
from the time the bonding neigh_setup is called.

commit 7d26bb103c4 "bonding: emit event when bonding changes MAC" didn't
take care to emit the NETDEV_CHANGEADDR event in bond_release, where bonding
actually changes the mac address (to all zeroes). As a result the neighbours
aren't deleted by the core networking code (which does so upon getting that
event).

This patch fixes Auto Power Saving configuration in ip101a_config_init
which was broken as there is no phy register write followed after
setting IP101A_APS_ON flag.
This patch also fixes the return value of ip101a_config_init.
Without this patch ip101a_config_init returns 2 which is not an error
accroding to IS_ERR and the mac driver will continue accessing 2 as
valid pointer to phy_dev resulting in memory fault.
