* Merge branch 'upstream-linus' of ↵Linus Torvalds2009-12-221-0/+19
|\ | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev * 'upstream-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev: pata_bf54x: handle portmuxing of pins through GPIO PORTs
| * pata_bf54x: handle portmuxing of pins through GPIO PORTsSonic Zhang2009-12-211-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | By default, the PATA pins are routed to the async address lines in which case, no peripheral muxing needs to be done. However, if the pins get routed through the GPIO PORTs pins, we need to make sure to request them so that the muxing is properly set up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The power management of some devices is handled through device types and device classes rather than through bus types. Since these devices may also benefit from using the run-time power management core, extend it so that the device type and device class run-time PM callbacks can be taken into consideration by it if the bus type callback is not defined. Update the run-time PM core documentation to reflect this change. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
| * | PM: Use pm_runtime_put_sync in system resumeAlan Stern2009-12-211-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1317) fixes a bug in the PM core. When a device is resumed following a system sleep, the core decrements the device's runtime PM usage counter but doesn't issue an idle notification if the counter reaches 0. This could prevent an otherwise unused device from being runtime-suspended again after the system sleep. The fix is to call pm_runtime_put_sync() instead of pm_runtime_put_noidle().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit f2511774863487e61b56a97da07ebf8dd61d7836 (PM: Add initcall_debug style timing for suspend/resume) introduced basic timing instrumentation, needed for a scritps/bootgraph.pl equivalent or humans, but it missed the fact that bus types and device classes which haven't been switched to using struct dev_pm_ops objects yet need special handling. As a result, the suspend/resume timing information is only available for devices whose bus types or device classes use struct dev_pm_ops objects, so the majority of devices is not covered. Fix this by adding basic suspend/resume timing instrumentation for devices whose bus types and device classes still don't use struct dev_pm_ops objects for power management. To reduce code duplication move the timing code to helper functions. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

| * | | | mm: Add notifier in pageblock isolation for balloon driversRobert Jennings2009-12-181-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Memory balloon drivers can allocate a large amount of memory which is not movable but could be freed to accomodate memory hotplug remove. Prior to calling the memory hotplug notifier chain the memory in the pageblock is isolated. Currently, if the migrate type is not MIGRATE_MOVABLE the isolation will not proceed, causing the memory removal for that page range to fail. Rather than failing pageblock isolation if the migrateteype is not MIGRATE_MOVABLE, this patch checks if all of the pages in the pageblock, and not on the LRU, are owned by a registered balloon driver (or other entity) using a notifier chain. If all of the non-movable pages are owned by a balloon, they can be freed later through the memory notifier chain and the range can still be isolated in set_migratetype_isolate().

The current kernel fifo API is not very widely used, because it has to many constrains. Only 17 files in the current 2.6.31-rc5 used it. FIFO's are like list's a very basic thing and a kfifo API which handles the most use case would save a lot of development time and memory resources. I think this are the reasons why kfifo is not in use: - The API is to simple, important functions are missing - A fifo can be only allocated dynamically - There is a requirement of a spinlock whether you need it or not - There is no support for data records inside a fifo So I decided to extend the kfifo in a more generic way without blowing up the API to much. The new API has the following benefits: - Generic usage: For kernel internal use and/or device driver. - Provide an API for the most use case. - Slim API: The whole API provides 25 functions. - Linux style habit. - DECLARE_KFIFO, DEFINE_KFIFO and INIT_KFIFO Macros - Direct copy_to_user from the fifo and copy_from_user into the fifo. - The kfifo itself is an in place member of the using data structure, this save an indirection access and does not waste the kernel allocator. - Lockless access: if only one reader and one writer is active on the fifo, which is the common use case, no additional locking is necessary. - Remove spinlock - give the user the freedom of choice what kind of locking to use if one is required. - Ability to handle records. Three type of records are supported: - Variable length records between 0-255 bytes, with a record size field of 1 bytes. - Variable length records between 0-65535 bytes, with a record size field of 2 bytes. - Fixed size records, which no record size field. - Preserve memory resource. - Performance! - Easy to use! This patch: Since most users want to have the kfifo as part of another object, reorganize the code to allow including struct kfifo in another data structure. This requires changing the kfifo_alloc and kfifo_init prototypes so that we pass an existing kfifo pointer into them. This patch changes the implementation and all existing users.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alan Stern noticed that e100 caused slab corruption. commit 98468efddb101f8a29af974101c17ba513b07be1 changed the allocation of cbs to use dma pools that don't return zeroed memory, especially the cb->status field used to track which cb to clean, causing (the visible) double freeing of skbs and a wrong free cbs count. Now the cbs are explicitly zeroed at allocation time.

This fails if device doesn't exist, and overall is a bad way to do the module parameter. Rather than fix borked code, just rewrite.
