There are currently no provisions in place to ensure that the scanning
task has been stopped when the interface is stopped or removed.
This can result in a WARNING at net/wireless/core.c:643 and other badness

This bug seems to be due to commit 27ae60f8f7 ("ipw2x00: replace
"ieee80211" with "libipw" where appropriate"), where Pavel did this:
- libipw_proc = proc_mkdir(DRV_NAME, init_net.proc_net);
+ libipw_proc = proc_mkdir("ieee80211", init_net.proc_net);
but then the cleanup was kept as
remove_proc_entry(DRV_NAME, init_net.proc_net);
in both places (both in the failure case and in the unload case). The
error string is also total crap, and says
"Unable to create " DRV_NAME " proc directory\n");
Even though it doesn't actually create a proc directory named DRV_NAME at all.
So that patch looks like total and utter crap to me. The commit message says
"Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface."
but the thing is, it really didn't fix anything but that one create
thing. It needs to fix all the other cases too.

Commit 27ae60f8f7 ("ipw2x00: replace "ieee80211" with "libipw" where
appropriate") changed DRV_NAME to be "libipw", but didn't properly fix
up the places where it was used to specify the name for the /proc/net/
directory.
For backwards compatibility reasons, that directory name remained
"ieee80211", but due to the DRV_NAME change, the error case printouts
and the cleanup functions now used "libipw" instead. Which made it all
fail badly.
For example, on module unload as reported by Randy:
WARNING: at fs/proc/generic.c:816 remove_proc_entry+0x156/0x35e()
name 'libipw'
because it's trying to unregister a /proc directory that obviously
doesn't even exist.
Clean it all up to use DRV_PROCNAME for the actual /proc directory name.

Commit 9f445cb29918dc488b7a9a92ef018599cce33df7[USB: musb: disable
double buffering for older RTL versions] tries to disable double
buffer mode by writing endpoint hw max packet size to TXMAP/RXMAP.
First the approach can break full speed and cause overflow problems.
We should always set those registers with the actual max packet size
from endpoint descriptor.
Second, the problem describe by commit 9f445cb299
was caused by musb gadget driver; nothing to do with RTL revision as
originaly suspected.
The real fix to the problem is to always use actual max packet
size from endpoint descriptor to config TXMAP/RXMAP registers.

Some actions like musb_platform_exit are only performed on module
removal and not on shutdown, which results in PHY being left enabled
on reboot at least. This is sometimes causing strange failures after
reboot (observed on OMAP3 pandora board), when DEVCTL does not report
VBUS state correctly due to unknown reasons (possibly because of
communication issues between musb IP and PHY). Running
musb_platform_exit before reset seems to resolve that issue.
Move some exit code from musb_remove() to musb_shutdown() so that it
is performed on both module removal and shutdown/reset. Also convert

Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate
using a protocol similar, but not identical to the AT keyboard protocol.
(Models known to be like this include 6110344, 6110668, 1390876, 1386887, and
possibly others.)
When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they
can be connected to a standard PC, with three caveats:
a) They can only use scancode set 3; requests to use anything else are
quietly ignored.
b) The AT Command to request Make, Break and Repeat codes is not properly
interpreted.
c) The top function keys on a 122 key keyboard, and the arrow/edit keys in
the middle of the board send non-standard scancodes.
C) is easily taken care of in userspace, by use of setkeycodes
B) can be taken care of by a userspace hack (that makes the kernel complain
in dmesg)
A) is fixable in theory, but on the keyboard i tested on (6110668), it seems
to be detected unoverridably as Set 2, causing userspace oddities that make
it harder to fix C).
Enclosed is a small patch to the kernel that fixes A) and B) in the kernel,
making it much easier to fix C) in userspace. It adds a single kernel
command line parameter that overrides the detection that sets these boards
as set 2, and instead of sending the Make-break-repeat command to the
keyboard, it sends the make-break command, which is properly recognized by
these keyboards. Software level key repeating seems to make up for the lack
of hardware repeat codes perfectly.
Without manually setting the command line parameter (tentatively named
atkbd.terminal), this code has no effect, and the driver works exactly as
before.

Part of the issue here was that Eric slipped in a debug hack for
testing the i915 IPS code before the intel_ips.c driver had landed.
This caused the driver to always use the full range of frequencies,
which is only legal when IPS tells us we have the headroom. Once that
hack was removed, there was confusion about the driver's frequency
clamping variables: max_delay is the driver's current limit on the
highest frequency the IPS driver wants us to use, while dev_priv->fmax
is the hardware-reported limit that the IPS driver can increase up to.
Tested with IPS driver loaded or not. Note that on Ironlake systems
without the IPS driver loaded this will result in a performance
reduction, and the inital warmup of frequency limits can impact
benchmarking on systems with IPS loaded.

If the controller is storing a split packet and therefore changing
d->res_count to zero between the two reads by the driver, we end up with
an end pointer that is not at a packet boundary, and therefore overflow
the buffer when handling the split packet.
To fix this, read the field once, atomically. The compiler usually
merges the two reads anyway, but for correctness, we have to enforce it.

Freeing an AR buffer page just to allocate a new page immediately

When handling an AR buffer that has been completely filled, we assumed
that its descriptor will not be read by the controller and can be
overwritten. However, when the last received packet happens to end at
the end of the buffer, the controller might not yet have moved on to the
next buffer and might read the branch address later. If we overwrite
and free the page before that, the DMA context will either go dead
because of an invalid Z value, or go off into some random memory.
To fix this, ensure that the descriptor does not get overwritten by
using only the actual buffer instead of the entire page for reassembling
the split packet. Furthermore, to avoid freeing the page too early,
move on to the next buffer only when some data in it guarantees that the
controller has moved on.
This should eliminate the remaining firewire-net problems.

When the controller had to split a received asynchronous packet into two
buffers, the driver tries to reassemble it by copying both parts into
the first page. However, if size + rest > PAGE_SIZE, i.e., if the yet
unhandled packets before the split packet, the split packet itself, and
any received packets after the split packet are together larger than one
page, then the memory after the first page would get overwritten.
To fix this, do not try to copy the data of all unhandled packets at
once, but copy the possibly needed data every time when handling
a packet.
This gets rid of most of the infamous crashes and data corruptions when
using firewire-net.

read_lock(&tasklist_lock);
tty_audit_push_task();

--> buf->mutex is locked with preemption disabled.
Solve this by acquiring a reference to the task struct under

Move all code which needs to be protected by sighand lock into
tty_audit_push_task() and use lock/unlock_sighand as we do not hold

The index variable to access the rate flags should be obtained from the
inner loop counter which corresponds to the rate table structure.This
fixes the invalid rate selection i.e when the supported basic rate is
invalid on a particular band and also the following warning message.

The "kgdb_connected" variable of debug_core just indicates whether or
not kgdbts is connected to the debug_core. It does not completely
prevent a script from trying invoke kgdbts again and possibly crashing
the system (see Call Trace below).
The configured variable in kgtbts can be used instead of
kgdb_connected instead of kgdb_connected. The cleanup_kgdbts() can
also be removed because there is no possible way to build kgdbts as a

The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus. This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.
The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.
The ehci and ohci blocks share a common clocking and PHY
infrastructure. Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.
Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.

The kernel build with CONFIG_OPROFILE and CPU_HOTPLUG enabled.
The oprofile is initialised using system timer in absence of hardware
counters supports. Oprofile isn't started from userland.
In this setup while doing a CPU offline the kernel hangs in infinite
for loop inside lock_hrtimer_base() function
This happens because as part of oprofile_cpu_notify(, it tries to
stop an hrtimer which was never started. These per-cpu hrtimers
are started when the oprfile is started.
echo 1 > /dev/oprofile/enable
This problem also existwhen the cpu is booted with maxcpus parameter
set. When bringing the remaining cpus online the timers are started
even if oprofile is not yet enabled.
This patch fix this issue by adding a state variable so that
these hrtimer start/stop is only attempted when oprofile is
started

Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.
The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.
Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.
We also reject samples where pressure is greater than pressure_max.

The iTCO_wdt driver erroneously releases the pci_dev, and causes PCI hotremove
to fail because of an incorrect usage count.
The probe for this driver does a for_each_pci_dev() which gets a reference for
a pci_dev when iTCO_wdt_init() is successful. The for_each_pci_dev() loop
puts a reference for a pci_dev when iTCO_wdt_init() fails, so the
iTCO_wdt_init() does not need to do any pci_dev_put()'s.
The only pci_dev_put() that is required is in the iTCO_wdt_cleanup() function.

Adding card detect callback function and card detect configuration
function for MMC1 Controller on OMAP4.
Card detect configuration function does initial configuration of the
MMC Control & PullUp-PullDown registers of Phoenix.
For MMC1 Controller, card detect interrupt source is
twl6030 which is non-gpio. The card detect call back function provides
card present/absent status by reading MMC Control register present
on twl6030.
Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
the suspend/resume initialization which was done in omap_hsmmc_gpio_init
previously is moved to the probe thus making it generic for both OMAP3 &
OMAP4.

The regulator driver was converted to get the needed data directly from

so regulators and num_regulators can go away. Then apart from the flag
indicating that the adc does a conversion, flags is only a copy of the
flags member of platform_data. This flag isn't needed to be returned by
mc13783_get_flags, so mc13783_get_flags now gets the flags from

GPIOs on these controller are multi-functional. If you decided to use

those pins to be reassigned as simple GPIOs (which may be triggered even
from userspace via 'export'). Same for the touchscreen controller pins.

reserve, let this bitmask be inside platform_data and provide some
