2011-02-23drm/vblank: Use memory barriers optimized for atomic_t instead of generics.Mario Kleiner1-3/+7
Documentation/atomic_ops.txt tells us that there are memory barriers optimized for atomic_inc and other atomic_t ops. Use these instead of smp_wmb(), and also to make the required memory barriers around vblank counter increments more explicit.

2011-02-23drm/vblank: Use abs64(diff_ns) for s64 diff_ns instead of abs(diff_ns)Mario Kleiner1-2/+2
Use of abs() wrongly wrapped diff_ns to 32 bit, which gives a 1/4000 probability of a missed vblank increment at each vblank irq reenable if the kms driver doesn't support high precision vblank timestamping.

2011-02-22i2c-omap: fix static suspend vs. runtime suspendKevin Hilman1-0/+28
When runtime PM is enabled, each OMAP i2c device is suspended after each i2c xfer. However, there are two cases when the static suspend methods must be used to ensure the devices are suspended: 1) runtime PM is disabled, either at compile time or dynamically via /sys/devices/.../power/control. 2) an i2c client driver uses i2c during it's suspend callback, thus leaving the i2c driver active (NOTE: runtime suspend transitions are disabled during system suspend, so i2c activity during system suspend will runtime resume the device, but not runtime (re)suspend it.) Since the actual work to suspend the device is handled by the subsytem, call the bus methods to take care of it. NOTE: This takes care of a known suspend problem on OMAP3 where the TWL RTC driver does i2c xfers during its suspend path leaving the i2c driver in an active state (since runtime suspend transistions are disabled.)

2011-02-21drm/i915: Do not handle backlight combination mode speciallyIndan Zupancic2-47/+0
The current code does not follow Intel documentation: It misses some things and does other, undocumented things. This causes wrong backlight values in certain conditions. Instead of adding tricky code handling badly documented and rare corner cases, don't handle combination mode specially at all. This way PCI_LBPC is never touched and weird things shouldn't happen. If combination mode is enabled, then the only downside is that changing the brightness has a greater granularity (the LBPC value), but LBPC is at most 254 and the maximum is in the thousands, so this is no real functional loss. A potential problem with not handling combined mode is that a brightness of max * PCI_LBPC is not bright enough. However, this is very unlikely because from the documentation LBPC seems to act as a scaling factor and doesn't look like it's supposed to be changed after boot. The value at boot should always result in a bright enough screen. IMPORTANT: However, although usually the above is true, it may not be when people ran an older (2.6.37) kernel which messed up the LBPC register, and they are unlucky enough to have a BIOS that saves and restores the LBPC value. Then a good kernel may seem to not work: Max brightness isn't bright enough. If this happens people should boot back into the old kernel, set brightness to the maximum, and then reboot. After that everything should be fine. For more information see the below links.

2011-02-21platform-drivers: x86: pmic: Use request_irq instead of chained handlerThomas Gleixner1-38/+12
There is no need to install a chained handler for this hardware. This is a plain x86 IOAPIC interrupt which is handled by the core code perfectly fine. There is nothing special about demultiplexing these gpio interrupts which justifies a custom hack. Replace it by a plain old interrupt handler installed with request_irq. That makes the code agnostic about the underlying primary interrupt hardware. The overhead for this is minimal, but it gives us the advantage of accounting, balancing and to detect interrupt storms. gpio interrupts are not really that performance critical.

2011-02-21md: avoid spinlock problem in blk_throtl_exitNeilBrown6-9/+8
blk_throtl_exit assumes that ->queue_lock still exists, so make sure that it does. To do this, we stop redirecting ->queue_lock to conf->device_lock and leave it pointing where it is initialised - __queue_lock. As the blk_plug functions check the ->queue_lock is held, we now take that spin_lock explicitly around the plug functions. We don't need the locking, just the warning removal. This is needed for any kernel with the blk_throtl code, which is which is 2.6.37 and later. Cc: stable@kernel.org Signed-off-by: NeilBrown <neilb@suse.de>

2011-02-20USB: Reset USB 3.0 devices on (re)discoveryLuben Tuikov1-11/+7
If the device isn't reset, the XHCI HCD sends SET ADDRESS to address 0 while the device is already in Addressed state, and the request is dropped on the floor as it is addressed to the default address. This sequence of events, which this patch fixes looks like this: usb_reset_and_verify_device() hub_port_init() hub_set_address() SET_ADDRESS to 0 with 1 usb_get_device_descriptor(udev, 8) usb_get_device_descriptor(udev, 18) descriptors_changed() --> goto re_enumerate: hub_port_logical_disconnect() kick_khubd() And then: hub_events() hub_port_connect_change() usb_disconnect() usb_disable_device() new device struct sets device state to Powered choose_address() hub_port_init() <-- no reset, but SET ADDRESS to 0 with 1, timeout! The solution is to always reset the device in hub_port_init() to put it in a known state. Note from Sarah Sharp: This patch should be queued for stable trees all the way back to 2.6.34, since that was the first kernel that supported configured device reset. The code this patch touches has been there since 2.6.32, but the bug would never be hit before 2.6.34 because the xHCI driver would completely reject an attempt to reset a configured device under xHCI.

I think the intention was that running_total be in the range of 0 to TRB_MAX_BUFF_SIZE-1, not 1 to TRB_MAX_BUFF_SIZE. So adding a running_total &= TRB_MAX_BUFF_SIZE - 1; fixes the problem.

2011-02-19drivers/char/pcmcia/ipwireless/main.c: Convert release_resource to ↵Julia Lawall1-20/+32
release_region/release_mem_region Request_region should be used with release_region, not release_resource. This patch contains a number of changes, related to calls to request_region, request_mem_region, and the associated error handling code. 1. For the call to request_region, the variable io_resource storing the result is dropped. The call to release_resource at the end of the function is changed to a call to release_region with the first two arguments of request_region as its arguments. The same call to release_region is also added to release_ipwireless. 2. The first call to request_mem_region is now tested and ret is set to -EBUSY if the the call has failed. This call was associated with the initialization of ipw->attr_memory. But the error handling code was testing ipw->common_memory. The definition of release_ipwireless also suggests that this call should be associated with ipw->common_memory, not ipw->attr_memory. 3. The second call to request_mem_region is now tested and ret is set to -EBUSY if the the call has failed. 4. The various gotos to the error handling code is adjusted so that there is no need for ifs. 5. Return the value stored in the ret variable rather than -1. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,E; @@ ( *x = request_region(...) | *x = request_mem_region(...) ) ... when != release_region(x) when != x = E * release_resource(x); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2011-02-18hwmon: (lm85) extend to support EMC6D103 chipsJan Beulich2-3/+22
The interface is identical EMC6D102, so all that needs to be added are some definitions and their uses. Registers apparently missing in EMC6D103S/EMC6D103:A2 compared to EMC6D103:A0, EMC6D103:A1, and EMC6D102 (according to the data sheets), but used unconditionally in the driver: 62[5:7], 6D[0:7], and 6E[0:7]. For that reason, EMC6D103S chips don't get enabled for the time being.

2011-02-18ath5k: Correct channel setting for AR2317 chipNikolay Ledovskikh1-0/+1
Correct channel setting function must be used for AR2317. When I tested ahb patch on bullet2 all seemed to work fine, but it couldn't connect another host (using ibss for example). During an analysis I observed that it's transmitting on another channel. I looked into madwifi code and understood that the problem is in channel setting function. So atheros RF2317 not fully handled in the current ath5k version and must be patched.
