2009-01-09Revert "driver core: move klist_children into private structure"Greg Kroah-Hartman3-30/+15
This reverts commit 11c3b5c3e08f4d855cbef52883c266b9ab9df879. Turns out that device_initialize shouldn't fail silently. This series needs to be reworked in order to get into proper shape.

2009-01-09firewire: core: fix sleep in atomic context due to driver core changeStefan Richter2-16/+20
Due to commit 2831fe6f9cc4e16c103504ee09a47a084297c0f3, "driver core: create a private portion of struct device", device_initialize() can no longer be called from atomic contexts. We now defer it until after config ROM probing. This requires changes to the bus manager code because this may use a device before it was probed.

2009-01-09mISDN: Add feature via MISDN_CTRL_FILL_EMPTY to fill fifo if emptyAndreas Eversberg9-45/+165
This prevents underrun of fifo when filled and in case of an underrun it prevents subsequent underruns due to jitter. Improve dsp, so buffers are kept filled with a certain delay, so moderate jitter will not cause underrun all the time -> the audio quality is highly improved. tones are not interrupted by gaps anymore, except when CPU is stalling or in high load.

2009-01-09x86: only scan the root bus in early PCI quirksAndi Kleen1-8/+14
We found a situation on Linus' machine that the Nvidia timer quirk hit on a Intel chipset system. The problem is that the system has a fancy Nvidia card with an own PCI bridge, and the early-quirks code looking for any NVidia bridge triggered on it incorrectly. This didn't lead a boot failure by luck, but the timer routing code selecting the wrong timer first and some ugly messages. It might lead to real problems on other systems. I checked all the devices which are currently checked for by early_quirks and it turns out they are all located in the root bus zero. So change the early-quirks loop to only scan bus 0. This incidently also saves quite some unnecessary scanning work, because early_quirks doesn't go through all the non root busses. The graphics card is not on bus 0, so it is not matched anymore.

2009-01-09block: fix bug in ptbl lookup cacheNeil Brown1-0/+1
Neil writes: Hi Jens, I've found a little bug for you. It was introduced by a6f23657d3072bde6844055bbc2290e497f33fbc block: add one-hit cache for disk partition lookup and has the effect of killing my machine whenever I try to assemble an md array :-( One of the devices in the array has partitions, and mdadm always deletes partitions before putting a whole-device in an array (as it can cause confusion). The next IO to that device locks the machine. I don't really understand exactly why it locks up, but it happens in disk_map_sector_rcu(). This patch fixes it. Which is due to a missing clear of the (now) stale partition lookup data. So clear that when we delete a partition. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-01-09Btrfs: explicitly mark the tree log root for writebackChris Mason1-0/+13
Each subvolume has an extent_state_tree used to mark metadata that needs to be sent to disk while syncing the tree. This is used in addition to the dirty bits on the pages themselves so that a single subvolume can be sent to disk efficiently in disk order. Normally this marking happens in btrfs_alloc_free_block, which also does special recording of dirty tree blocks for the tree log roots. Yan Zheng noticed that when the root of the log tree is allocated, it is added to the wrong writeback list. The fix used here is to explicitly set it dirty as part of tree log creation.

2009-01-09[S390] hvc_iucv: Special handling of IUCV HVC devicesHendrik Brueckner1-12/+28
This patch introduces special handling of the IUCV HVC console device. If the first IUCV HVC terminal is used as (preferred) Linux console, and needs some special handling for hangup. The hvc_iucv_private structure contains a flag to indicate whether a IUCV HVC device is used as a console. A terminal acting as "console" behaves different if a tty hangup occurs: If the iucv communication path is severed, a tty hangup is not triggered (because the HVC layer does not notify its back-end in that case). Instead, the console session is left unchanged and the IUCV HVC device is reset to allow re-connects. Note: Any output between the disconnect and a re-connect is discarded.
