89c581b3fb iwlwifi: fix suspend/resume and its usage of pci saved state
Here we do two things:

First, revert "iwlwifi: save PCI state before suspend, restore after
resume".  That misguided patch led to being unable to use iwlwifi
devices after resume.

Next, indicate to PCI driver that the saved PCI state is valid during suspend.

We restore PCI state and enable the device when network interface is created,
similarly PCI state is saved and the device is disabled when network interface
is removed. Thus, when .suspend is called the PCI state is saved and device
is disabled. This is the case even if an interface is never created as PCI
state is saved and device disabled during .probe.

PCI driver assumes PCI state is saved in .suspend. Saving the state at this
time will save state of disabled device and thus cause problems during
resume (resuming a disabled device). We thus indicate directly to PCI
driver that current PCI saved state is valid.

Under memory pressure, we may not be able to allocate a new skb for
new packets.  If the allocation fails, ath5k_tasklet_rx will exit but
will leave a buffer in the list with a NULL skb, eventually triggering

Extract the skb allocation from ath5k_rxbuf_setup() and change the
tasklet to allocate the next skb before accepting a packet.

7b7a799d66 sunhme: Fix Quattro HME irq registration on proble failures
Currently, the sunhme driver installs SBus Quattro interrupt handler 
when at least one HME card was initialized correctly and at least one 
Quattro card is present. This breaks when a Quattro card fails 
initialization for whatever reason - IRQ is registered and OOPS happens 
when it fires.

The solution, as suggested by David Miller, was to keep track which 
cards of the Quattro bundles have been initialized, and request/free the 
Quattro IRQ only when all four devices have been successfully 
initialized.

The patch only touches SBus initialization - PCI init already resets the 
card pointer to NULL on init failure.

The patch has been tested on Sun E3500 with SBus and PCI single HME 
cards and one PCI Quattro HME card in a situation where any PCI card 
failed init when the SBus routines tried to init them by mistake.

Additionally it replaces Quattro request_irq panic with error return - 
if this card fails to work, at least let the others work.

Tested on E450 with PCI HME and PCI Quad HME.

cfbf84fcbc tun: Fix unicast filter overflow
Tap devices can make use of a small MAC filter set via the
TUNSETTXFILTER ioctl.  The filter has a set of exact matches
plus a hash for imperfect filtering of additional multicast
addresses.  The current code is unbalanced, adding unicast
addresses to the multicast hash, but only checking the hash
against multicast addresses.  This results in the filter
dropping unicast addresses that overflow the exact filter.
The fix is simply to disable the filter by leaving count set
to zero if we find non-multicast addresses after the exact
match table is filled.

152abd139c 3c509: Fix resume from hibernation for PnP mode.
From: Ondrej Zary <linux@rainbow-software.org>

last year, I posted a patch which fixed hibernation on 3c509
cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I
stopped using hibernation (as it did not work with my new IT8212 RAID
controller).

Now I fixed it and noticed that 3c509 does not wake up properly
anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig
down/up makes the card work again in PnP mode. However, in ISA mode,
ifconfig up ends with "No such device" error.

Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only
some statistics-related change. So the cause of the problem must be
somewhere else.

This patch makes the resume work in PnP mode, but it's still not
enough for ISA mode.

71822faa3b sungem: Soft lockup in sungem on Netra AC200 when switching interface up
From: Ilkka Virta <itvirta@iki.fi>

In the lockup situation the driver seems to go off in an eternal storm
of interrupts right after calling request_irq(). It doesn't actually
do anything interesting in the interrupt handler. Since connecting the link
afterwards works, something later in initialization must fix this.

Looking at gem_do_start() and gem_open(), it seems that the only thing
done while opening the device after the request_irq(), is a call to
napi_enable().

I don't know what the ordering requirements are for the
initialization, but I boldly tried to move the napi_enable() call
inside gem_do_start() before the link state is checked and interrupts
subsequently enabled, and it seems to work for me. Doesn't even break
anything too obvious...

355423d084 r8169: Don't update statistics counters when interface is down
Some Realtek chips (RTL8169sb/8110sb in my case) are unable to retrieve
ethtool statistics when the interface is down. The process stays in
endless loop in rtl8169_get_ethtool_stats. This is because these chips
need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is
cleared when the interface is going down. It's better to update statistics
only when the interface is up and otherwise return copy of statistics
grabbed when the interface was up (in rtl8169_close).

It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected.

if (limit <= 0)
	goto test_failed;

In the last iteration, limit is decremented after the test to 0.
If just thereafter test() succeeds and a break occurs, the goto
still occurs because limit is 0.

3fff0179e3 virtio-pci: do not oops on config change if driver not loaded
The host really shouldn't be notifying us of config changes
before the device status is VIRTIO_CONFIG_S_DRIVER or
VIRTIO_CONFIG_S_DRIVER_OK.

However, if we do happen to be interrupted while we're not
attached to a driver, we really shouldn't oops. Prevent
this simply by checking that device->driver is non-NULL
before trying to notify the driver of config changes.

Problem observed by doing a "set_link virtio.0 down" with
QEMU before the net driver had been loaded.

b6018958a5 pxamci: enable DMA for write ops after CMD/RESP
With the PXA270 MMC hardware, there seems to be an issue of
data corruption on writes where a 4KB data block is offset
by one byte.

If we delay enabling the DMA for writes until after the CMD/RESP
has finished, the problem seems to be fixed.

06cc1c8800 ricoh_mmc: Use suspend_late/resume_early
If ricoh_mmc suspends before sdhci_pci, it will pull the card
out from under the controller, which could leave the system in
a very confused state.

Using suspend_late/resume_early ensures that sdhci_pci suspends first
and resumes second.

cc30d60e4c mmci: Add support for ST Micro derivate
This patch adds support for the ST Microelectronics version of
the PL180 PrimeCell. They use designer ID 0x80 and have a few
alterations/bugfixes related to open drain and HW flow control.
They also add some SDIO registers, I am unsure if these are
in ST HW only or if this is things also added in later ARM
revisions, but they are included in the mmci.h file for
completeness.

d96be879ff mmc: Add a MX2/MX3 specific SDHC driver
This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically
the same as in the MX1, but unlike the MX1 controller the MX2
controller just works as expected. Since the MX1 driver has more
workarounds for bugs than anything else I had no success with supporting
MX1 and MX2 in a sane way in one driver.
