280b9a9de1 ath9k_hw: do not enable the MIB interrupt in the interrupt mask register
The interrupt is no longer handling it. While it shouldn't fire (wraparound
is highly unlikely), the consequences would be fatal (interrupt storm).
Disable the interrupt to prevent that from happening.

d0f21fe658 rt2x00: fix voltage setting for RT3572/RT3592
According to the vendor driver v2.6.0.1, during the rf register init the SRAM
voltage should be increased to 1.35V and after 1ms decreased back to 1.2V. This
patch adds the field setting of LDO_CFG0_LDO_CORE_VLEVEL accordingly.

da25186fc6 mwifiex: fix skb length issue when send a command to firmware
When we send a command to firmware, we assumed that cmd_size
will be always less than or equal to the structure size of
host_cmd_ds_command. However, this is no longer true after
we added AP support. There are some AP commands that Custom
IE TLVs are included in command buffer, hence the cmd_size
gets enlarged by the TLV data. We need to increase the skb
length for the extra data.

b5031ed1be xen: Use correct masking in xen_swiotlb_alloc_coherent.
When running 32-bit pvops-dom0 and a driver tries to allocate a coherent
DMA-memory the xen swiotlb-implementation returned memory beyond 4GB.

The underlaying reason is that if the supplied driver passes in a
DMA_BIT_MASK(64) ( hwdev->coherent_dma_mask is set to 0xffffffffffffffff)
our dma_mask will be u64 set to 0xffffffffffffffff even if we set it to
DMA_BIT_MASK(32) previously. Meaning we do not reset the upper bits.
By using the dma_alloc_coherent_mask function - it does the proper casting
and we get 0xfffffffff.

This caused not working sound on a system with 4 GB and a 64-bit
compatible sound-card with sets the DMA-mask to 64bit.

On bare-metal and the forward-ported xen-dom0 patches from OpenSuse a coherent
DMA-memory is always allocated inside the 32-bit address-range by calling
dma_alloc_coherent_mask.

This patch adds the same functionality to xen swiotlb and is a rebase of the
original patch from Ronny Hegewald which never got upstream b/c the
underlaying reason was not understood until now.

The original email with the original patch is in:
http://old-list-archives.xen.org/archives/html/xen-devel/2010-02/msg00038.html
the original thread from where the discussion started is in:

a96874a2a9 Intel xhci: Only switch the switchable ports
With a previous patch to enable the EHCI/XHCI port switching, it switches
all the available ports.

The assumption is not correct because the BIOS may expect some ports
not switchable by the OS.

There are two more registers that contains the information of the switchable
and non-switchable ports.

This patch adds the checking code for the two register so that only the
switchable ports are altered.

This patch should be backported to kernels as old as 3.0, that contain
commit ID 69e848c209 "Intel xhci: Support
EHCI/xHCI port switching."

aa209eef3c staging: vt6656: [BUG] - Failed connection, incorrect endian.
Hi,

This patch fixes a bug with driver failing to negotiate a connection.

The bug was traced to commit
203e4615ee
staging: vt6656: removed custom definitions of Ethernet packet types

In that patch, definitions in include/linux/if_ether.h replaced ones
in tether.h which had both big and little endian definitions.

include/linux/if_ether.h only refers to big endian values, cpu_to_be16
should be used for the correct endian architectures.

d947d63592 Merge tag 'v3.6-rc1-iio-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
IIO fixes for v3.6-rc1 set 2

A few simple fixes.

1)Fix up some possible divide by zero issues in various drivers.

2)Prevent a memory leak in an error path in lis3l02dq

3)Make sure the PTR_ERR call in at91_adc matches the
check for IS_ERR just above it rather than using a different
pointer.

Merges fine against v3.6rc4

e6391a1828 staging: comedi: das08: Correct AI encoding for das08jr-16-ao
The element of `das08_boards[]` for the 'das08jr-16-ao' board has the
`ai_encoding` member set to `das08_encode12`.  It should be set to
`das08_encode16` same as the 'das08jr/16' board.  After all, this board
has 16-bit AI resolution.

The description of the A/D LSB register at offset 0 seems incorrect in
the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI
resolution is only 12 bits.  The diagrams of the A/D LSB and MSB
registers show 15 data bits and a sign bit, which matches what the
software expects for the `das08_encode16` AI encoding method.

This turned out to be due to memory corruption caused by long-broken
PIO code in drivers/mmc/host/omap.c.  (Previously, this driver had
been using DMA; but the above commit caused the MMC driver to fall
back to PIO mode with an unmodified Kconfig.)

The PIO code, added with the rest of the driver in commit
730c9b7e66 ("[MMC] Add OMAP MMC host
driver"), confused bytes with 16-bit words.  This bug caused memory
located after the PIO transfer buffer to be corrupted with transfers
larger than 32 bytes.  The driver also did not increment the buffer
pointer after the transfer occurred.  This bug resulted in data
corruption during any transfer larger than 64 bytes.

3550ccdb9d mmc: card: Skip secure erase on MoviNAND; causes unrecoverable corruption.
For several MoviNAND eMMC parts, there are known issues with secure
erase and secure trim.  For these specific MoviNAND devices, we skip
these operations.

Specifically, there is a bug in the eMMC firmware that causes
unrecoverable corruption when the MMC is erased with MMC_CAP_ERASE
enabled.

9623b5b919 mmc: dw_mmc: Disable low power mode if SDIO interrupts are used
The documentation for the dw_mmc part says that the low power
mode should normally only be set for MMC and SD memory and should
be turned off for SDIO cards that need interrupts detected.

The best place I could find to do this is when the SDIO interrupt
was first enabled.  I rely on the fact that dw_mci_setup_bus()
will be called when it's time to reenable.

e74f3a9c99 mmc: dw_mmc: fix error handling in PIO mode
Data transfer will be continued until all the bytes are transmitted,
even if data crc error occurs during a multiple-block data transfer.
This means RXDR/TXDR interrupts will occurs until data transfer is
terminated. Early setting of host->sg to NULL prevents going into
xxx_data_pio functions, hence permanent unhandled RXDR/TXDR interrupts
occurs. And checking error interrupt status in the xxx_data_pio functions
is no need because dw_mci_interrupt does do the same. This patch also
removes it.

9b2026a125 mmc: dw_mmc: correct mishandling error interrupt
Datasheet of SYNOPSYS mentions that DTO(Data Transfer Over) interrupt
will be raised even if some error interrupts, however it is actually
found that DTO does not occur. SYNOPSYS has confirmed this issue.
Current implementation defers the call of tasklet_schedule until DTO
when the error interrupts is happened. This patch fixes error handling.

182c908159 mmc: dw_mmc: amend using error interrupt status
RINTSTS status includes masked interrupts as well as unmasked.
data_status and cmd_status are set by value of RINTSTS in interrupt handler
and tasklet finally uses it to decide whether error is happened or not.
In addition, MINTSTS status is used for setting data_status in PIO.
Masked error interrupt will not be handled and that status can be considered
non-error case.

077d40731e mmc: atmel-mci: not busy flag has also to be used for read operations
Even if the datasheet says that the not busy flag has to be used only
for write operations, it's false except for version lesser than v2xx.

Not waiting on the not busy flag for read operations can cause the
controller to hang-up during the initialization of some SD cards
with DMA after the first CMD6 -- the next command is sent too early.

"if (clock == 0)" where ESDHC_SYSTEM_CONTROL has been operated.  This
causes SDHCI card-detection function being broken.  Fix the regression
by moving "if (clock == 0)" above ESDHC_SYSTEM_CONTROL operation.

78b495c39a UBI: fix a horrible memory deallocation bug
UBI was mistakingly using 'kfree()' instead of 'kmem_cache_free()' when
freeing "attach eraseblock" structures in vtbl.c. Thankfully, this happened
only when we were doing auto-format, so many systems were unaffected. However,
there are still many users affected.

It is strange, but the system did not crash and nothing bad happened when
the SLUB memory allocator was used. However, in case of SLOB we observed an
crash right away.

This problem was introduced in 2.6.39 by commit
"6c1e875 UBI: add slab cache for ubi_scan_leb objects"

A note for stable trees:
  Because variable were renamed, this won't cleanly apply to older kernels.
  Changing names like this should help:
	1. ai -> si
	2. aeb_slab_cache -> seb_slab_cache
	3. new_aeb -> new_seb

cab32f39dc can: mcp251x: avoid repeated frame bug
The MCP2515 has a silicon bug causing repeated frame transmission, see section
5 of MCP2515 Rev. B Silicon Errata Revision G (March 2007).

Basically, setting TXBnCTRL.TXREQ in either SPI mode (00 or 11) will eventually
cause the bug. The workaround proposed by Microchip is to use mode 00 and send
a RTS command on the SPI bus to initiate the transmission.

85e87870fa net: usbnet: fix softirq storm on suspend
Suspending an open usbnet device results in constant
rescheduling of usbnet_bh.

commit 65841fd5 "usbnet: handle remote wakeup asap"
refactored the usbnet_bh code to allow sharing the
urb allocate and submit code with usbnet_resume. In
this process, a test for, and immediate return on,
ENOLINK from rx_submit was unintentionally dropped.

The rx queue will not grow if rx_submit fails,
making usbnet_bh reschedule itself.  This results
in a softirq storm if the error is persistent.
rx_submit translates the usb_submit_urb error
EHOSTUNREACH into ENOLINK, so this is an expected
and persistent error for a suspended device. The
old code tested for this condition and avoided
rescheduling.  Putting this test back.

fcbc50da77 drm/i915: only enable sdvo hotplug irq if needed
Avoid constant wakeups caused by noisy irq lines when we don't even care
about the irq. This should be particularly useful for i945g/gm where the
hotplug has been disabled:

    drm/i915: disable sdvo hotplug on i945g/gm

v2: While at it, remove the bogus hotplug_active read, and do not mask
hotplug_active[0] before checking whether the irq is needed, per discussion
with Daniel on IRC.

c1f05264d8 drm/i915/edp: get the panel delay before powering up
In order to setup the i2c channel, we power up the panel
via ironlake_edp_panel_vdd_on, however it requires
intel_dp->panel_power_up_delay to be initialised,
which hasn't been setup yet.

So move things around so we set the panel power up
values first then init the i2c stuff.

This is one step to fixing the eDP panel in the MBP
from uninitialised state.

9bfc8da00b HID: Only dump input if someone is listening
Going through the motions of printing the debug message information
takes a long time; using the keyboard can lead to a 160 us irqsoff
latency. This patch skips hid_dump_input() when there are no open
handles, which brings latency down to 100 us.
