2008-01-31Add new driver 'rndis_wlan' for wireless RNDIS devices.Jussi Kivilinna
New driver for wireless RNDIS devices. So far only known chip that uses wireless RNDIS is Broadcom 4320. Driver detects all RNDIS devices that have RNDIS wireless physical medium. At least following devices are detected: Buffalo WLI-U2-KG125S U.S. Robotics USR5421 Belkin F5D7051 Linksys WUSB54GSv2 Linksys WUSB54GSC Asus WL169gE Eminent EM4045 BT Voyager 1055 Linksys WUSB54GSv1 U.S. Robotics USR5420 BUFFALO WLI-USB-G54 Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

2008-01-31Move usbnet.h and rndis_host.h to include/linux/usbJussi Kivilinna
Move headers usbnet.h and rndis_host.h to include/linux/usb and fix includes for drivers/net/usb modules. Headers are moved because rndis_wlan will be outside drivers/net/usb in drivers/net/wireless and yet need these headers.

2008-01-31iwlwifi: Fix uCode error on associationGregory Greenman
The problem is that priv->assoc_id is set when assoc. resp frame is received. But, when it is set, LQ cmd is still not sent to the uCode, it is done from bg_post_assoc, which is called through a workqueue. On the other hand, when a tx arrives at the moment when this flag is set, but LQ is still not sent, the if condition in tx_skb will not hold and the frame will not be dropped. Thus, it will be sent through which is still not in the sta table in the uCoded.

2008-01-31iwlwifi: initialize geo/channel information during probeReinette Chatre
The geo/channel information is obtained from the EEPROM, which is read during probe. We can thus set up channel information at this time. This helps us to support ioctl commands that rely on this before the interface is brought up. Clearly matches _init_channel_map with _free_channel_map and _init_geos with _free_geos to ensure functions calling these routines can also call their cleanup routines. Fixes a few bugs: - if channel information is not available when ioctl commands are issued then we get a NULL pointer oops. Having channel information set up during probe we can deal with ioctl commands without requiring interface to be brought up. This fixes bug: http://www.bughost.org/bugzilla/show_bug.cgi?id=1552 - Fix potential problem if user triggers probe/remove/probe sequence. The value of priv->channel_count was used to determine if channel map is set up. This value was never reset when channel map was removed. - Fix memory leak: priv->modes need to be freed when device removed.

2008-01-31b43legacy: fix MAC control and microcode initStefano Brivio
This zeros out all microcode related memory before loading the microcode. This also fixes initialization of the MAC control register. The _only_ place where we overwrite the contents of the MAC control register is at the beginning of b43_chip_init(). All other places must do read() -> mask/set -> write() to not overwrite existing bits. This also adds a longer delay for waiting for the microcode to initialize itself. It seems that the current timeout is sufficient on all available devices, but there's no real reason why we shouldn't wait for up to one second. Slow embedded devices might exist. Better safe than sorry. While at it, fix naming of MACCTL values. This patch by Michael Buesch has been ported to b43legacy.

2008-01-31sched: fix high wake up latencies with FAIR_USER_SCHEDSrivatsa Vaddagiri
The reason why we are getting better wakeup latencies for !FAIR_USER_SCHED is because of this snippet of code in place_entity(): if (!initial) { /* sleeps upto a single latency don't count. */ if (sched_feat(NEW_FAIR_SLEEPERS) && entity_is_task(se)) ^^^^^^^^^^^^^^^^^^ vruntime -= sysctl_sched_latency; /* ensure we never gain time by being placed backwards. */ vruntime = max_vruntime(se->vruntime, vruntime); } NEW_FAIR_SLEEPERS feature gives credit for sleeping only to tasks and not group-level entities. With the patch attached, I could see that wakeup latencies with FAIR_USER_SCHED are restored to the same level as !FAIR_USER_SCHED. Signed-off-by: Ingo Molnar <mingo@elte.hu>
