2012-10-04bcmdhd: use the wiphy from private data structure (i.e., wl_priv)Mursalin Akon
problem: The macro wiphy_from_scan retrieves wiphy from wl_priv->escan_info.wiphy which is in turn set by a 'scan' initiated from kernel space (like scheduled scan) or from user space (like iwlist command). Without a scan, a 'connect' crashes in function wl_inform_single_bss, with NULL pointer access, as the variable wiphy (in turn, wl->escan_info.wiphy) is not initialized properly. solution: wireless_device data structures maintained for both STA and P2P mode point to the same wiphy (see, wl_cfgp2p_register_ndev in wl_cfgp2p.c). So, irrespective of whatever wireless_device is in use, a scan will always set wl_priv->escan_info.wiphy to the same wiphy. There is no point in getting wiphy using wl_priv->escan_info.wiphy, rather use the wiphy referred by all wireless_device structures.

When device is idle and display is on, the minimal cpu frequency can drop to 51mhz. Since it takes several tens of millisecond to ramp up cpu freq, the delay impact negatively the performance of low latency CPU bound tasks. Given the power savings of several milliwatts running cpu at 51mhz comparing to 102mhz or 204 mhz at idle, the idle cpu freq is hence raised to 102mhz for smart panel device and 204mhz for dump panel devices.

2012-09-10ARM: mutex: use generic atomic_dec-based implementation for ARMv6+Will Deacon
Commit a76d7bd96d65 ("ARM: 7467/1: mutex: use generic xchg-based implementation for ARMv6+") removed the barrier-less, ARM-specific mutex implementation in favour of the generic xchg-based code. Since then, a bug was uncovered in the xchg code when running on SMP platforms, due to interactions between the locking paths and the MUTEX_SPIN_ON_OWNER code. This was fixed in 0bce9c46bf3b ("mutex: place lock in contended state after fastpath_lock failure"), however, the atomic_dec-based mutex algorithm is now marginally more efficient for ARM (~0.5% improvement in hackbench scores on dual A15). This patch moves ARMv6+ platforms to the atomic_dec-based mutex code.

2012-09-10ARM: 7467/1: mutex: use generic xchg-based implementation for ARMv6+Will Deacon
The open-coded mutex implementation for ARMv6+ cores suffers from a severe lack of barriers, so in the uncontended case we don't actually protect any accesses performed during the critical section. Furthermore, the code is largely a duplication of the ARMv6+ atomic_dec code but optimised to remove a branch instruction, as the mutex fastpath was previously inlined. Now that this is executed out-of-line, we can reuse the atomic access code for the locking (in fact, we use the xchg code as this produces shorter critical sections). This patch uses the generic xchg based implementation for mutexes on ARMv6+, which introduces barriers to the lock/unlock operations and also has the benefit of removing a fair amount of inline assembly code.

2012-09-04usbnet: fix skb traversing races during unlink(v2)Ming Lei
Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid recursive locking in usbnet_stop()) fixes the recursive locking problem by releasing the skb queue lock before unlink, but may cause skb traversing races: - after URB is unlinked and the queue lock is released, the refered skb and skb->next may be moved to done queue, even be released - in skb_queue_walk_safe, the next skb is still obtained by next pointer of the last skb - so maybe trigger oops or other problems This patch extends the usage of entry->state to describe 'start_unlink' state, so always holding the queue(rx/tx) lock to change the state if the referd skb is in rx or tx queue because we need to know if the refered urb has been started unlinking in unlink_urbs. The other part of this patch is based on Huajun's patch: always traverse from head of the tx/rx queue to get skb which is to be unlinked but not been started unlinking.

2012-09-04ASoC: dapm: Use DAPM mutex for DAPM ops instead of codec mutexLiam Girdwood
It has now become necessary to use a DAPM mutex instead of the codec mutex to lock the DAPM operations. This is due to the recent multi component support and forth coming Dynamic PCM updates. Currently we lock DAPM operations with the codec mutex of the calling RTD context. However, DAPM operations can span the whole card context and all components. This patch updates the DAPM operations that use the codec mutex to now use the DAPM mutex PCM subclass for all DAPM ops. We also add a mutex subclass for DAPM init and PCM operations.
