There is a race between call_usermodehelper_keys, __call_usermodehelper and wait_for_helper. It should only happen if preemption is enabled or on a virtualized system. If the cpu is preempted or put to sleep by the hypervisor in __call_usermodehelper between the creation of the wait_for_helper thread and the second check on sub_info->wait, the whole execution of wait_for_helper including the complete call and the continuation after the wait_for_completion in call_usermodehelper_keys can have happened before __call_usermodehelper checks sub_info->wait for the second time. Since sub_info can already have been clobbered, sub_info->wait could be zero and complete is called a second time with an invalid argument. This has happened on s390. It took me only three days to find out .. Thanks to Arnd Bergmann for his help to spot this bug. Kenneth Lee also sent the same patch independently. Signed-off-by:

This patch - works around a bug in the I2C bridge that makes the initialization of the TDA10046 fail on recent LifeView cards - puts the AGC output to tristate in sleep mode. This is necessary for recent hybrid cards that switch the AGC via tristateing. Signed-off-by:

Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do internal locking. This is a nasty trap for code that might call idr functions from different contexts; for example, it seems perfectly reasonable to call idr_get_new() from process context and idr_remove() from interrupt context -- but with the current locking this would lead to a potential deadlock. The simplest fix for this is to just convert the idr locking to use spin_lock_irqsave(). In particular, this fixes a very complicated locking issue detected by lockdep, involving the ib_ipoib driver's priv->lock and dev->_xmit_lock, which get involved with the ib_sa module's query_idr.lock.

The pattern is set after trying to compute the prefix table, which tries to use it. Initialize it before calling compute_prefix_tbl, make compute_prefix_tbl consistently use only the data from struct ts_bm and remove the now unnecessary arguments. Signed-off-by:

Michael Krufky authored
The device, Medion 7134, has two saa7134 chips on it, but only one of them is functional in the current saa7134 driver. This patch adds autodetection for the second, unsupported saa7134 chip, as SAA7134_BOARD_MD7134_BRIDGE_2, and displays a message to the user (in dmesg) indicating that the second chip isn't yet functional. This is useful for users, since two instances of the saa7134 driver will spawn. This patch will prevent confusion by warning the user that only one of the chips on the board are functional. There are other versions of the SAA7134_BOARD_MD7134 with only a single saa7134 bridge/decoder -- those devices will not be affected by this patch. Only devices containing the second chip will display the warning. Signed-off-by:

There are already some supported devices that contain two saa713x chips on-board, where only one of these chips is currently functional in the driver. We are already printing a warning message for the second saa7134 decoder in SAA7134_BOARD_AVERMEDIA_A169_B. This patch alters that case to make it generic, so that other cards in the same situation can use it. Signed-off-by:

- Added support for AVerMedia A169 Dual Analog tuner card (dual saa7134 decoders - only 1 working right now) - Added autodetection for both parts of the card. It shows up like 2 cards, B1 and B - Enabled tuner B1, SVIDEO on B1 and composite1 through SVIDEO, FIXME: B is more or less dead at this point and I suspect the FM-radio is on the B part of the board Adrian Bunk: slightly adapted to 2.6.16 Signed-off-by:

Jack Steiner identified a problem where XPC can cause a silent data corruption. On module load, the placement may cause the xpc_remote_copy_buffer to span two physical pages. DMA transfers are done to the start virtual address translated to physical. This patch changes the buffer from a statically allocated buffer to a kmalloc'd buffer. Dean Nelson reviewed this before posting. I have tested it in the configuration that was showing the memory corruption and verified it works. I also added a BUG_ON statement to help catch this if a similar situation is encountered. Signed-off-by:
