2010-08-02staging: ti dspbridge: use stream id instead of kernel addressErnesto Ramos
Send stream ids to the user instead of handles, then when the id is coming from user dspbridge can retrive the handle using id and avoid using invalid handles. Signed-off-by: Ernesto Ramos <ernesto@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-08-02staging: ti dspbridge: use processor handle from context instead of user'sErnesto Ramos

2010-08-02staging: ti dspbridge: avoid errors if node handle is zeroErnesto Ramos
As 'zero' can be a perfectly good id, it can be picked up as a NULL from userspace, avoid issues in API and user apps if node handle is zero. Signed-off-by: Ernesto Ramos <ernesto@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-08-02staging: ti dspbridge: use node id instead of kernel addressErnesto Ramos
Use idr kernel library to send/receive node ids to the user instead of kernel address. This id will be use to access the node handles at the kernel side, if id does not match to any handle error -EFAULT is returned.

2010-08-02staging: ti dspbridge: avoid possible NULL dereference panicErnesto Ramos
When dsp_notifications array is received from user, dspbridge verifies the array has valid pointers and dsp_notification structures. However, these structures contain pointers that need to be checked for valid handles. Signed-off-by: Ernesto Ramos <ernesto@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-08-02tg3: Improve small packet performanceMatt Carlson
smp_mb() inside tg3_tx_avail() is used twice in the normal tg3_start_xmit() path (see illustration below). The full memory barrier is only necessary during race conditions with tx completion. We can speed up the tx path by replacing smp_mb() in tg3_tx_avail() with a compiler barrier. The compiler barrier is to force the compiler to fetch the tx_prod and tx_cons from memory. In the race condition between tg3_start_xmit() and tg3_tx(), we have the following situation: tg3_start_xmit() tg3_tx() if (!tg3_tx_avail()) BUG(); ... if (!tg3_tx_avail()) netif_tx_stop_queue(); update_tx_index(); smp_mb(); smp_mb(); if (tg3_tx_avail()) if (netif_tx_queue_stopped() && netif_tx_wake_queue(); tg3_tx_avail()) With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to tg3_start_xmit() as shown above to properly order netif_tx_stop_queue() and tg3_tx_avail() to check the ring index. If it is not strictly ordered, the tx queue can be stopped forever. This improves performance by about 3% with 2 ports running bi-directional 64-byte packets.

2010-08-02V4L/DVB: sms: Convert IR support to use the Remote Controller coreMauro Carvalho Chehab
Rewrites the siano IR implementation. The previous implementation were non-standard. As such, it has issues if more than one device registers IR, as there used to have some static constants used during protocol decoding phase. Also, it used to implement its on RAW decoder, and only for RC5. The new code uses RC core subsystem for handling IR. This brings several new features to the driver, including: - Allow to dynamically replace the IR keycodes; - Supports all existing raw decoders (JVC, NEC, RC-5, RC-6, SONY); - Supports lirc dev; - Doesn't have race conditions when more than one sms IR is registered; - The code size for the IR implementation is very small; - it exports the IR features via /sys/class/rc.
