2009-11-16perf_event: Optimize perf_output_lock()Peter Zijlstra
The purpose of perf_output_{un,}lock() is to: 1) avoid publishing incomplete data [ possible when publishing a head that is ahead of an entry that is still being written ] 2) guarantee fwd progress [ a simple refcount on pending writers doesn't need to drop to 0, making it so would end up implementing something like forced quiecent states of RCU ] To satisfy the above without undue complexity it serializes between CPUs, this means that a pending writer can only be the same cpu in a nested context, and since (under normal operation) a cpu always makes progress we're good -- if the head is only published when the bottom most writer completes. Now we don't need to disable IRQs in order to serialize between CPUs, disabling preemption ought to be sufficient, esp since we already deal with nesting due to NMIs. This avoids potentially expensive (and needless) local IRQ disable/enable ops.

2009-11-16leds-gpio: fix possible crash on OF device unbindingDmitry Eremin-Solenikov
If there are leds present in the OF tree, but the GPIOs for (some) of them are unavailable, led_data doesn't get populated with correct devices. Then, on device unbinding, one can crash the kernel. Workaround this by setting led->gpio to invalid value early. Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@gmail.com> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>
2009-11-16backlight: Fix backlight limiting on spitz/corgi devicesPavel Machek
On spitz (& similar) machines, if battery is running low, backlight needs to be limited to lower step.

2009-11-16net: Fix the rollback test in dev_change_name()Eric Dumazet
net: Fix the rollback test in dev_change_name() In dev_change_name() an err variable is used for storing the original call_netdevice_notifiers() errno (negative) and testing for a rollback error later, but the test for non-zero is wrong, because the err might have positive value as well - from dev_alloc_name(). It means the rollback for a netdevice with a number > 0 will never happen. (The err test is reordered btw. to make it more readable.)

2009-11-16ALSA: ice1724 - make some bitfields unsignedDan Carpenter
This is a clean up and doesn't change the behavior. Bit fields should always be unsigned. Otherwise pm_suspend_enabled will be -1 when you want it to be 1. The other bad thing is that the sparse checker will complain 36 times if they aren't unsigned. The other bitfields in that struct are unsigned already.

2009-11-15TI Davinci EMAC : Fix Console Hang when bringing the interface downSriram
In the NAPI poll function(emac_poll), check for netif_running() is unnecassary. In addition to associated runtime overhead, it also results in a continuous softirq loop when the interface is brought down under heavy traffic(tested wit Traffic Generator). Once the interface is disabled, the poll function always returns zero(with the check for netif_running) and napi_complete() would never get called resulting in softirq loop.

2009-11-16Bluetooth: Fix regression with L2CAP configuration in Basic ModeGustavo F. Padovan
Basic Mode is the default mode of operation of a L2CAP entity. In this case the RFC (Retransmission and Flow Control) configuration option should not be used at all. Normally remote L2CAP implementation should just ignore this option, but it can cause various side effects with other Bluetooth stacks that are not capable of handling unknown options.

2009-11-16Bluetooth: Set general bonding security for ACL by defaultAndrei Emeltchenko
This patch fixes double pairing issues with Secure Simple Paring support. It was observed that when pairing with SSP enabled, that the confirmation will be asked twice. http://www.spinics.net/lists/linux-bluetooth/msg02473.html This also causes bug when initiating SSP connection from Windows Vista. The reason is because bluetoothd does not store link keys since HCIGETAUTHINFO returns 0. Setting default to general bonding fixes these issues.
