2011-07-13mwifiex: add cfg80211 handler for set_bitrate_maskYogesh Ashok Powar
Currently, setting only legacy bitrates on 2.4GHz band are supported. Mode 802.11b/g/bg is enabled based on bitrates selection. If only CCK bitrates selected then 802.11b mode is enabled. If only OFDM bitrates are selected then 802.11g mode is enabled. For both: CCK and OFDM rates 802.11bg mixed mode is enabled.

2011-07-13ath5k: disable 32KHz sleep clock operation by defaultFelix Fietkau
While 32 KHz sleep clock might provide some power saving benefits, it is also a major source of stability issues, on OpenWrt it produced some reproducible data bus errors on register accesses on several different MIPS platforms. All the Atheros drivers that I can find do not enable this feature, so it makes sense to leave it disabled in ath5k as well.

2011-07-13ath9k_hw: Fix incorrect key_miss handlingSenthil Balasubramanian
Decryping frames on key_miss handling shouldn't be done for Michael MIC failed frames as h/w would have already decrypted such frames successfully anyway. Also leaving CRC and PHY error(where the frame is going to be dropped anyway), we are left to prcoess Decrypt error for which s/w decrypt is selected anway and so having key_miss as a separate check doesn't serve anything. So making key_miss handling mutually exlusive with other RX status handling makes much more sense. This patch addresses an issue with STA not reporting MIC failure events resulting in STA being disconnected immediately.

2011-07-13ACPI: Fix lockdep false positives in acpi_power_off()Rafael J. Wysocki
All ACPICA locks are allocated by the same function, acpi_os_create_lock(), with the help of a local variable called "lock". Thus, when lockdep is enabled, it uses "lock" as the name of all those locks and regards them as instances of the same lock, which causes it to report possible locking problems with them when there aren't any. To work around this problem, define acpi_os_create_lock() as a macro and make it pass its argument to spin_lock_init(), so that lockdep uses it as the name of the new lock. Define this macron in a Linux-specific file, to minimize the resulting modifications of the OS-independent ACPICA parts. This change is based on an earlier patch from Andrea Righi and it addresses a regression from 2.6.39 tracked as https://bugzilla.kernel.org/show_bug.cgi?id=38152 Signed-off-by: Rafael J.

2011-07-13IB/srp: Avoid duplicate devices from LUN scanBart Van Assche
SCSI scanning of a channel:id:lun triplet in Linux works as follows (function scsi_scan_target() in drivers/scsi/scsi_scan.c): - If lun == SCAN_WILD_CARD, send a REPORT LUNS command to the target and process the result. - If lun != SCAN_WILD_CARD, send an INQUIRY command to the LUN corresponding to the specified channel:id:lun triplet to verify whether the LUN exists. So a SCSI driver must either take the channel and target id values in account in its quecommand() function or it should declare that it only supports one channel and one target id. Currently the ib_srp driver does neither. As a result scanning the SCSI bus via e.g. rescan-scsi-bus.sh causes many duplicate SCSI devices to be created. For each 0:0:L device, several duplicates are created with the same LUN number and with (C:I) != (0:0). Fix this by declaring that the ib_srp driver only supports one channel and one target id.

Each biquad has five signed, 24bit, fixed-point coefficients representing the range -1...1. The five biquad coefficients can be uploaded in one atomic operation into on-chip coefficient RAM. There are also a few prescale, postscale and mixing coefficients, in the same numeric format and range (a negative coefficient inverts phase).

2011-07-13rcu: Prevent RCU callbacks from executing before scheduler initializedPaul E. McKenney
Under some rare but real combinations of configuration parameters, RCU callbacks are posted during early boot that use kernel facilities that are not yet initialized. Therefore, when these callbacks are invoked, hard hangs and crashes ensue. This commit therefore prevents RCU callbacks from being invoked until after the scheduler is fully up and running, as in after multiple tasks have been spawned. It might well turn out that a better approach is to identify the specific RCU callbacks that are causing this problem, but that discussion will wait until such time as someone really needs an RCU callback to be invoked (as opposed to merely registered) during early boot.
