2011-03-22pwm_backlight: add check_fb() hookRobert Morell
In systems with multiple framebuffer devices, one of the devices might be blanked while another is unblanked. In order for the backlight blanking logic to know whether to turn off the backlight for a particular framebuffer's blanking notification, it needs to be able to check if a given framebuffer device corresponds to the backlight. This plumbs the check_fb hook from core backlight through the pwm_backlight helper to allow platform code to plug in a check_fb hook.

2011-03-22mbp_nvidia_bl: remove DMI dependencyMatthew Garrett
This driver only has to deal with two different classes of hardware, but right now it needs new DMI entries for every new machine. It turns out that there's an ACPI device that uniquely identifies Apples with backlights, so this patch reworks the driver into an ACPI one, identifies the hardware by checking the PCI vendor of the root bridge and strips out all the DMI code. It also changes the config text to clarify that it works on devices other than Macbook Pros and GPUs other than nvidia.

2011-03-22tty: stop using "delayed_work" in the tty layerLinus Torvalds
Using delayed-work for tty flip buffers ends up causing us to wait for the next tick to complete some actions. That's usually not all that noticeable, but for certain latency-critical workloads it ends up being totally unacceptable. As an extreme case of this, passing a token back-and-forth over a pty will take two ticks per iteration, so even just a thousand iterations will take 8 seconds assuming a common 250Hz configuration. Avoiding the whole delayed work issue brings that ping-pong test-case down to 0.009s on my machine. In more practical terms, this latency has been a performance problem for things like dive computer simulators (simulating the serial interface using the ptys) and for other environments (Alan mentions a CP/M emulator).

2011-03-21veth: Fix the byte countersEric W. Biederman
Commit 44540960 "veth: move loopback logic to common location" introduced a bug in the packet counters. I don't understand why that happened as it is not explained in the comments and the mut check in dev_forward_skb retains the assumption that skb->len is the total length of the packet. I just measured this emperically by setting up a veth pair between two noop network namespaces setting and attempting a telnet connection between the two. I saw three packets in each direction and the byte counters were exactly 14*3 = 42 bytes high in each direction. I got the actual packet lengths with tcpdump. So remove the extra ETH_HLEN from the veth byte count totals. Signed-off-by: Eric W. Biederman <ebiederm@aristanetworks.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-03-21macvlan: Fix use after free of struct macvlan_port.Eric W. Biederman
When the macvlan driver was extended to call unregisgter_netdevice_queue in 23289a37e2b127dfc4de1313fba15bb4c9f0cd5b, a use after free of struct macvlan_port was introduced. The code in dellink relied on unregister_netdevice actually unregistering the net device so it would be safe to free macvlan_port. Since unregister_netdevice_queue can just queue up the unregister instead of performing the unregiser immediately we free the macvlan_port too soon and then the code in macvlan_stop removes the macaddress for the set of macaddress to listen for and uses memory that has already been freed. To fix this add a reference count to track when it is safe to free the macvlan_port and move the call of macvlan_port_destroy into macvlan_uninit which is guaranteed to be called after the final macvlan_port_close.

2011-03-21can: c_can: Do basic c_can configuration _before_ enabling the interruptsJan Altenberg
I ran into some trouble while testing the SocketCAN driver for the BOSCH C_CAN controller. The interface is not correctly initialized, if I put some CAN traffic on the line, _while_ the interface is being started (which means: the interface doesn't come up correcty, if there's some RX traffic while doing 'ifconfig can0 up'). The current implementation enables the controller interrupts _before_ doing the basic c_can configuration. I think, this should be done the other way round. The patch below fixes things for me.

2011-03-21Reduce sequential pointer derefs in scsi_error.c and reduce size as wellJesper Juhl
This patch reduces the number of sequential pointer derefs in drivers/scsi/scsi_error.c This has been submitted a number of times over a couple of years. I believe this version adresses all comments it has gathered over time. Please apply or reject with a reason. The benefits are: - makes the code easier to read. Lots of sequential derefs of the same pointers is not easy on the eye. - theoretically at least, just dereferencing the pointers once can allow the compiler to generally slightly faster code, so in theory this could also be a micro speed optimization. - reduces size of object file (tiny effect: on x86-64, in at least one configuration, the text size decreased from 9439 bytes to 9400) - removes some pointless (mostly trailing) whitespace.

2011-03-21matroxfb: remove incorrect Matrox G200eV supportGary Hade
Remove incorrect Matrox G200eV support that was previously added by commit e3a1938805d2e81b27d3d348788644f3bad004f2 A serious issue with the incorrect G200eV support that reproduces on the Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login banner, login prompt, etc) on the console when X is not running and total lack of text on all of the virtual consoles after X is started. Any concerns that the incorrect code (upstream since October 2008) has been successfully used on non-IBM G200eV equipped system(s) appear to be unwarranted. In addition to the serious/non-intermittent nature of issues that have been spotted on IBM systems, complete removal of the incorrect code is clearly supported by the following Matrox (Yannick Heneault) provided input: "It impossible that this patch should have work on a system. The patch only declare the G200eV as a regular G200 which is not case. Many registers are different, including at least the PLL programming sequence. If the G200eV is programmed like a regular G200, it will not display anything." v1 - Initial patch that removed the incorrect code for _all_ G200eV equipped systems. v2 - Darrick Wong provided patch that blacklisted the incorrect code on G200eV equipped IBM systems leaving it enabled on all G200eV equipped non-IBM systems. v3 - Same code changes included with v1 plus additional justification for complete removal of the incorrect code.

2011-03-21Move lis3lv02d drivers to drivers/miscJean Delvare
The lis3lv02d drivers aren't hardware monitoring drivers, so the don't belong to drivers/hwmon. Move them to drivers/misc, short of a better home.

The hp_accel driver isn't a hardware monitoring driver, so it doesn't belong to drivers/hwmon. Move it to drivers/platform/x86, assuming HP doesn't ship non-x86 laptops.

2011-03-21Let Kconfig handle lis3lv02d dependenciesJean Delvare
The dependencies between the various lis3lv02d drivers make it impossible to split them to different directories, while we really want to do this. Move handling of dependencies from Makefile to Kconfig, to make the move possible at all.

2011-03-21hwmon: (sht15) Fix integer overflow in humidity calculationVivien Didelot
An integer overflow occurs in the calculation of RHlinear when the relative humidity is greater than around 30%. The consequence is a subtle (but noticeable) error in the resulting humidity measurement.

2011-03-21i2c-pxa2xx: pass of_node from platform driver to adapter and publishSebastian Andrzej Siewior
the of_node will auto-publish devices which are added to the device tree. Commit 925bb9c6 aka ("of/i2c: Fix module load order issue caused by of_i2c.c) moved the of_i2c_register_devices() function from the i2c core back to the drivers. This patch does the same thing for the pxa driver.

2011-03-21i2c-pxa2xx: check timeout correctlySebastian Andrzej Siewior
timeout here maybe 0 if the event occured and a task with a higher priority stole the cpu and we were sleeping longer than the timeout value we specified. In case of a real timeout I changed the error code to I2C_RETRY so we retry the transfer.

2011-03-21i2c-pxa2xx: Add PCI support for PXA I2C controllerSebastian Andrzej Siewior
The Sodaville I2C controller is almost the same as found on PXA2xx. The difference: - the register are at a different offset - no slave support The PCI probe code adds three platform devices which are probed then by the platform code. The X86 part also adds dummy clock defines because we don't have HW clock support.
