2013-02-19HID: add ThingM blink(1) USB RGB LED supportVivien Didelot7-0/+315
The ThingM blink(1) is an open source hardware USB RGB LED. It contains an internal EEPROM, allowing to configure up to 12 light patterns. A light pattern is a RGB color plus a fade time. This driver registers a LED class instance with additional sysfs attributes to support basic functions such as setting RGB colors, fade and playing. Other functions are still accessible through the hidraw interface. At this time, the only documentation for the device is the firmware source code from ThingM, plus a few schematics. They are available at: https://github.com/todbot/blink1 This patch is version 3. It updates the name of the source file, the driver and the led sysfs entry, according to comments from Jiri Kosina and Simon Wood.

2013-02-19rwsem-spinlock: Implement writer lock-stealing for better scalabilityYuanhan Liu1-45/+24
We (Linux Kernel Performance project) found a regression introduced by commit: 5a505085f043 mm/rmap: Convert the struct anon_vma::mutex to an rwsem which converted all anon_vma::mutex locks rwsem write locks. The semantics are the same, but the behavioral difference is quite huge in some cases. After investigating it we found the root cause: mutexes support lock stealing while rwsems don't. Here is the link for the detailed regression report: https://lkml.org/lkml/2013/1/29/84 Ingo suggested adding write lock stealing to rwsems: "I think we should allow lock-steal between rwsem writers - that will not hurt fairness as most rwsem fairness concerns relate to reader vs. writer fairness" And here is the rwsem-spinlock version. With this patch, we got a double performance increase in one test box with following aim7 workfile: FILESIZE: 1M POOLSIZE: 10M 10 fork_test /usr/bin/time output w/o patch /usr/bin/time_output with patch -- Percent of CPU this job got: 369% Percent of CPU this job got: 537% Voluntary context switches: 640595016 Voluntary context switches: 157915561 We got a 45% increase in CPU usage and saved about 3/4 voluntary context switches.

2013-02-19rwsem: Implement writer lock-stealing for better scalabilityAlex Shi1-29/+46
Commit 5a505085f043 ("mm/rmap: Convert the struct anon_vma::mutex to an rwsem") changed struct anon_vma::mutex to an rwsem, which caused aim7 fork_test performance to drop by 50%. Yuanhan Liu did the following excellent analysis: https://lkml.org/lkml/2013/1/29/84 and found that the regression is caused by strict, serialized, FIFO sequential write-ownership of rwsems. Ingo suggested implementing opportunistic lock-stealing for the front writer task in the waitqueue. Yuanhan Liu implemented lock-stealing for spinlock-rwsems, which indeed recovered much of the regression - confirming the analysis that the main factor in the regression was the FIFO writer-fairness of rwsems. In this patch we allow lock-stealing to happen when the first waiter is also writer. With that change in place the aim7 fork_test performance is fully recovered on my Intel NHM EP, NHM EX, SNB EP 2S and 4S test-machines.

2013-02-19bonding: fix bond_release_all inconsistencies[email protected]1-117/+18
This patch fixes the following inconsistencies in bond_release_all: - IFF_BONDING flag is not stripped from slaves - MTU is not restored - no netdev notifiers are sent Instead of trying to keep bond_release and bond_release_all in sync I think we can re-use bond_release as the environment for calling it is correct (RTNL is held). I have been running tests for the past week and they came out successful. The only way for bond_release to fail is for the slave to be attached in a different bond or to not be a slave but that cannot happen as RTNL is held and no slave manipulations can be achieved. V2: As suggested bond_release is renamed to __bond_release_one with a new parameter "all" introduced so to avoid calling unnecessary code while destroying a bond, and a wrapper for it called bond_release is created because of ndo_del_link. bond_release_all() is removed.

2013-02-19b43: Increase number of RX DMA slotsLarry Finger1-1/+1
Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G were due to overflow of the RX DMA ring buffer, which was created with 64 slots. That finding reminded me that I was seeing similar crashed on a netbook, which also has a relatively slow processor. After increasing the number of slots to 128, runs on the netbook that previously failed now worked; however, I found that 109 slots had been used in one test. For that reason, the number of slots is being increased to 256.

These functions are used by the tilegx onchip network driver, and it's useful to be able to load that driver as a module. Signed-off-by: Chris Metcalf <[email protected]> Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]>

kmalloc() fails. When memory allocation using, kmalloc() fails, report appropriate error value. Signed-off-by: Kumar Amit Mehta <[email protected]> Signed-off-by: John W. Linville <[email protected]>
2013-02-18net: wireless: orinoco: orinoco_usb.c: fix DMA buffers on stackKumar Amit Mehta1-2/+9
This patch fixes an instance of DMA buffer on stack(being passed to usb_control_msg) for the wireless USB version of the Agere Orinoco card driver. It also fixes the missing audit for the return value of firmware download routine. Found using smatch. Signed-off-by: Kumar Amit Mehta <[email protected]> Signed-off-by: John W.

2013-02-18rtlwifi: usb: allocate URB control message setup_packet and data buffer ↵Jussi Kivilinna1-16/+28
separately rtlwifi allocates both setup_packet and data buffer of control message urb, using shared kmalloc in _usbctrl_vendorreq_async_write. Structure used for allocating is: struct { u8 data[254]; struct usb_ctrlrequest dr; }; Because 'struct usb_ctrlrequest' is __packed, setup packet is unaligned and DMA mapping of both 'data' and 'dr' confuses ARM/sunxi, leading to memory corruptions and freezes. Patch changes setup packet to be allocated separately. [v2]: - Use WARN_ON_ONCE instead of WARN_ON Cc: <[email protected]> Signed-off-by: Jussi Kivilinna <[email protected]> Signed-off-by: John W.
