commit 3b274f44d2ca05f719fe39947b6a5293a2dbd8fd upstream
The cell_edac driver is setting the edac_mode field of the csrow's to an
incorrect value, causing the sysfs show routine for that field to go out
of an array bound and Oopsing the kernel when used.

commit 978ccaa8ea5d8c7bf6b676209f2fc126eae6355b upstream
We can get the following oops from gpio_get_value_cansleep() when a GPIO
controller doesn't provide a get() callback:
Unable to handle kernel paging request for instruction fetch
Faulting instruction address: 0x00000000

It's OK to request the value of *any* GPIO; most GPIOs are bidirectional,
so configuring them as outputs just enables an output driver and doesn't
disable the input logic.
So the problem is that gpio_get_value_cansleep() isn't making the same
sanity check that gpio_get_value() does: making sure this GPIO isn't one
of the atypical "no input logic" cases.

commit 5ba2f67afb02c5302b2898949ed6fc3b3d37dcf1 upstream
NULL function pointers are very bad security wise. This one got caught by
kerneloops.org quite a few times, so it's happening in the field....
Fix is simple, check the function pointer for NULL, like 6 other places
in the same function are already doing.

commit 4b40893918203ee1a1f6a114316c2a19c072e9bd upstream
Olaf Kirch noticed that the i915_set_status_page() function of the i915
kernel driver calls ioremap with an address offset that is supplied by
userspace via ioctl. The function zeroes the mapped memory via memset
and tells the hardware about the address. Turns out that access to that
ioctl is not restricted to root so users could probably exploit that to
do nasty things. We haven't tried to write actual exploit code though.
It only affects the Intel G33 series and newer.

commit c767c1c6f1febbd1351cc152bba6e37889322d17 upstream
Minor musb_hdrc updates:
- so it'll build on DaVinci, given relevant platform updates;
* remove support for an un-shipped OTG prototype
* rely on gpiolib framework conversion for the I2C GPIOs
* the <asm/arch/hdrc_cnf.h> mechanism has been removed
- catch comments up to the recent removal of the per-SOC header
with the silicon configuration data;
- and remove two inappropriate "inline" declarations which
just bloat host side code.
There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>
changes needed in this driver, catching up to the relocation
of most of the include/asm-arm/arch-* contents.

commit 29bac7b7661bbbdbbd32bc1e6cedca22f260da7f upstream
Bugfix for the new CDC Ethernet code: as part of activating the
network interface's USB link, make sure its link management code
knows whether the interface is open or not.
Without this fix, the link won't work right when it's brought up
before the link is active ... because the initial notification it
sends will have the wrong link state (down, not up). Makes it
hard to bridge these links (on the host side), among other things.

commit f9e9cff613b8239ce9159735aa662c9c85b478bf upstream
The new composite framework revealed a weakness in the
s3c2410_udc driver gadget register function. Instead of
checking if speed asked for was USB_LOW_SPEED upon
usb_gadget_register() to deny service, it checked only
for USB_FULL_SPEED, thus denying service to usb high
speed capable gadgets (like g_ether).

commit 71b7497c078a97e2afb774ad7c1f8ff5bdda8a60 upstream
This patch (as1149) fixes an obscure problem in OHCI polling. In the
current code, if the RHSC interrupt status flag turns on at a time
when RHSC interrupts are disabled, it will remain on forever:
The interrupt handler is the only place where RHSC status
gets turned back off;
The interrupt handler won't turn RHSC status off because it
doesn't turn off status flags if the corresponding interrupt
isn't enabled;
RHSC interrupts will never get enabled because
ohci_root_hub_state_changes() doesn't reenable RHSC if RHSC
status is on!
As a result we will continue polling indefinitely instead of reverting
to interrupt-driven operation, and the root hub will not autosuspend.
This particular sequence of events is not at all unusual; in fact
plugging a USB device into an OHCI controller will usually cause it to
occur.
Of course, this is a bug. The proper thing to do is to turn off RHSC
status just before reading the actual port status values. That way
either a port status change will be detected (if it occurs before the
status read) or it will turn RHSC back on. Possibly both, but that
won't hurt anything.
We can still check for systems in which RHSC is totally broken, by
re-reading RHSC after clearing it and before reading the port
statuses. (This re-read has to be done anyway, to post the earlier
write.) If RHSC is on but no port-change statuses are set, then we
know that RHSC is broken and we can avoid re-enabling it.

commit 4a511bc3f5829bc18428bcf11c25417a79d09396 upstream
This patch (as1134) attempts to improve the way we handle OHCI
controllers with broken Root Hub Status Change interrupt support. In
these controllers the RHSC interrupt bit essentially never turns off,
making RHSC interrupts useless -- they have to remain permanently
disabled.
Such controllers should still be allowed to turn off their root hubs
when no devices are attached. Polling for new connections can
continue while the root hub is suspended. The patch implements this
feature. (It won't have much effect unless CONFIG_PM is enabled and
CONFIG_USB_SUSPEND is disabled, but since the overhead is very small
we may as well do it.)

commit 4233df6b748193d45f79fb7448991a473061a65d upstream
As I've reported, ath9k currently fails utterly when fragmentation
is enabled. This makes ath9k "support" hardware fragmentation by
not supporting fragmentation at all to avoid the double-free issue.
The patch also changes mac80211 to report errors from the driver
operation to userspace.
That hack in ath9k should be removed once the rate control algorithm
it has is fixed, and we can at that time consider removing the hw
fragmentation support entirely since it's not used by any driver.

commit f382a0a8e9403c6d7f8b2cfa21e41fefb5d0c9bd upstream
Lockdep warns about the mdio_lock taken with interrupts enabled then later
taken from interrupt context. Initially, I considered changing these
to spin_lock_irq/spin_unlock_irq, but then I looked at atl1e_phy_init()
and saw that it calls msleep(). Sleeping while holding a spinlock is
not allowed either.
In the probe path, we haven't registered the interrupt handler, so
it can't poke at this card yet. It's before we call register_netdev(),
so I don't think any other threads can reach this card either. If I'm
right, we don't need a spinlock at all.

The atmel-mci driver sometimes fails data transfers like this:
mmcblk0: error -5 transferring data
end_request: I/O error, dev mmcblk0, sector 2749769
end_request: I/O error, dev mmcblk0, sector 2749777
It turns out that this might be caused by the BLKR register (which
contains the block size and the number of blocks being transfered) being
initialized too late. This patch moves the initialization of BLKR so
that it contains the correct value before the block transfer command is
sent.
This error is difficult to reproduce, but if you insert a long delay
(mdelay(10) or thereabouts) between the calls to atmci_start_command()
and atmci_submit_data(), all transfers seem to fail without this patch,
while I haven't seen any failures with this patch.

The new A-Link Bluetooth dongle is another one based on the BCM2046 chip
from Broadcom and it also needs to send HCI_Reset before it becomes fully
operational. Without the quirk it will show a lot of I/O errors.

Targus and Belkin have come out with new Bluetooth 2.1 capable dongles
using the latest BCM2046 chip from Broadcom. Both of them are so called
HID proxy dongles and they need to send HCI_Reset before they become

The transfer buffer of an URB will be automatically freed when using
the URB_FREE_BUFFER transfer_flag. So the extra calls to kfree() will
cause a double free.

The Swarm IDE driver uses a release method which is defined in the driver
itself thus potentially oopsable. The simple fix would be to just leak
the device but this patch goes the full length and moves the entire
handling of the platform device in the platform code and retains only
the platform driver code in drivers/ide/mips/swarm.c.

Apparently, 'xcount' being 0 does not mean 0 bytes for TRM290; it means 4 bytes,
judging from the code immediately preceding this check. So, we must never try
to "split" the PRD for TRM290.
This is probably never hit anyway -- with the DMA buffers aligned to at least
512 bytes and ATAPI DMA not being used for non block I/O commands...

Correct firmware type to MTS
Correct audio routing for composite/s-video
Add DVB-T detection.
This patch uses the eeprom hash method for detection as the vendor/product
ids are also used for the DIGIVOX_AD. This may be a clone of the same
product. Explanatory text has been added prior to the hask look-up in
anticipation that it may help others.
The following has been tested to work:
Analogue TV (PAL-I)
Composite In
DVB-T (UK Crystal Palace)
USB AUDIO
The following has not been tested but probably works:

There is a buffer overflow in drivers/media/video/uvc/uvc_ctrl.c:
INFO: 0xf2c5ce08-0xf2c5ce0b. First byte 0xa1 instead of 0xcc
INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975
...
A fixed size 8-byte buffer is allocated, and a variable size field is read
into it; there is no particular bound on the size of the field (it is
dependent on hardware and configuration) and it can overflow [also
verified by inserting printk's.]
The patch attempts to size the buffer to the correctly.

Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.
Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.
This patch needs to go into the current release of the kernel, as this driver
is currently broken.
(Thanks to Eberhard Kaltenhaeuser for helping out to debug this issue.)

The functions dvb_dmxdev_section_callback, dvb_dmxdev_ts_callback,
dvb_dmx_swfilter_packet, dvb_dmx_swfilter_packets, dvb_dmx_swfilter and
dvb_dmx_swfilter_204 may be called from both interrupt and process
context. Therefore they need to be protected by spin_lock_irqsave()
instead of spin_lock().
This fixes a deadlock discovered by lockdep.
