2009-04-06intel-iommu: Fix oops in device_to_iommu() when devices not found.David Woodhouse
It's possible for a device in the drhd->devices[] array to be NULL if it wasn't found at boot time, which means we have to check for that case. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2009-04-06PCI Hotplug: acpiphp: grab refcount on p2p subordinate busAlex Chiang
If a logical hot unplug (remove) is performed on a bridge claimed by acpiphp and then acpiphp is unloaded, we will encounter an oops. This is because acpiphp will access the bridge's subordinate bus, which was released by the user's prior hot unplug. The solution is to grab a reference on the subordinate PCI bus. This will prevent the bus from release until acpiphp is unloaded.

2009-04-06PCI: don't corrupt enable_cnt when doing manual resource alignmentYuji Shimada
This patch fixes breakage of of enable_cnt in quirk_resource_alignment. Currently, quirk_resource_alignment calls pci_disable_device. pci_disable_device decrements enable_cnt, so that enable_cnt becomes -1. The patch disables memory decoding, writing command register directly. So enable_cnt is not broken.

2009-04-06PCI: annotate pci_rescan_bus as __ref, not __devinitAlex Chiang
pci_rescan_bus was annotated as __devinit, which is wrong, because it will never be part of device initialization. Howevever, we can't simply drop the annotation, because then we get section warnings about calling pci_scan_child_bus (which is correctly marked as __devinit). pci_rescan_bus will only get built when CONFIG_HOTPLUG is set, meaning that __devinit is a nop, so we know that pci_scan_child_bus has not been freed. Annotate as __ref to silence modpost. Signed-off-by: Alex Chiang <achiang@hp.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2009-04-06PCI: Setup disabled bridges even if buses are addedYuji Shimada
This patch sets up disabled bridges even if buses have already been added. pci_assign_unassigned_resources is called after buses are added. pci_assign_unassigned_resources calls pci_bus_assign_resources. pci_bus_assign_resources calls pci_setup_bridge to configure BARs of bridges. Currently pci_setup_bridge returns immediately if the bus have already been added. So pci_assign_unassigned_resources can't configure BARs of bridges that were added in a disabled state; this patch fixes the issue. On logical hot-add, we need to prevent the kernel from re-initializing bridges that have already been initialized. To achieve this, pci_setup_bridge returns immediately if the bridge have already been enabled. We don't need to check whether the specified bus is a root bus or not. pci_setup_bridge is not called on a root bus, because a root bus does not have a bridge. The patch adds a new helper function, pci_is_enabled. I made the function name similar to pci_is_managed. The codes which use enable_cnt directly are changed to use pci_is_enabled.

This patch adds support for the new Apple models incorporating an Nvidia chipset. Apple still uses the same protocol as on older models, but the registers moved to a different address. To do this, two sets of functions are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH function. The initial code has been contributed by Hu Gang <hugang@soulinfo.com>. The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook Pro 5. Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing brightness within X doesn't work, if using Nvidia's proprietary graphics driver with no known fix at present. Changing brightness on a text console or using the open-source driver does work. MacBook Pro 5 has a known bug where the initial brightness after bootup is the last recently used brightness (in Mac OSX), while the firmware reports maximum. Impossible to fix.

2009-04-06leds: move h1940-leds's probe function to .devinit.textUwe Kleine-König

Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late.

2009-04-06leds: add BD2802GU LED driverKim Kyuwon
ROHM BD2802GU is a RGB LED controller attached to i2c bus and specifically engineered for decoration purposes. This RGB controller incorporates lighting patterns and illuminates. This driver is designed to minimize power consumption, so when there is no emitting LED, it enters to reset state. And because the BD2802GU has lots of features that can't be covered by the current LED framework, it provides Advanced Configuration Function(ADF) mode, so that user applications can set registers of BD2802GU directly. Here are basic usage examples : ; to turn on LED (not blink) $ echo 1 > /sys/class/leds/led1_R/brightness ; to blink LED $ echo timer > /sys/class/leds/led1_R/trigger $ echo 1 > /sys/class/leds/led1_R/delay_on $ echo 1 > /sys/class/leds/led1_R/delay_off ; to turn off LED $ echo 0 > /sys/class/leds/led1_R/brightness [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

It's useful for usecases as n810's keypad leds that could be triggered by the gpio event generated when user slides up to show the keypad. We also provide means for userland to tell us what is the desired brightness for that special led when it goes on so userland could use information from ambient light sensors and not set led brightness too high if it's not necessary.

Add bindings to support LEDs defined as of_platform devices in addition to the existing bindings for platform devices. New options in Kconfig allow the platform binding code and/or the of_platform code to be turned on. The of_platform code is of course only available on archs that have OF support. The existing probe and remove methods are refactored to use new functions create_gpio_led(), to create and register one led, and delete_gpio_led(), to unregister and free one led. The new probe and remove methods for the of_platform driver can then share most of the common probe and remove code with the platform driver. The suspend and resume methods aren't shared, but they are very short. The actual led driving code is the same for LEDs created by either binding. The OF bindings are based on patch by Anton Vorontsov <avorontsov@ru.mvista.com>. They have been extended to allow multiple LEDs per device.

2009-04-06cpm_uart: Disable CPM udbg when re-initing CPM uart, even if not the console.Scott Wood
Previously, if udbg was using the CPM uart, and the normal CPM uart driver was enabled, but the console was directed elsewhere, udbg would not be stopped prior to initialization. This resulted in udbg hanging forever waiting for the CPM to process a descriptor. Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2009-04-06cpm_uart: Initialize port.dev before it's used.Scott Wood
Previously, this caused NULL to sometimes be passed as a device to the DMA code. With recent DMA changes, that now causes a BUG(). Signed-off-by: Scott Wood <scottwood@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2009-04-06md/raid1 - don't assume newly allocated bvecs are initialised.NeilBrown
Since commit d3f761104b097738932afcc310fbbbbfb007ef92 newly allocated bvecs aren't initialised to NULL, so we have to be more careful about freeing a bio which only managed to get a few pages allocated to it. Otherwise the resync process crashes. This patch is appropriate for 2.6.29-stable.
