2008-10-16wait: kill is_sync_wait()Tejun Heo
is_sync_wait() is used to distinguish between sync and async waits. Basically sync waits are the ones initialized with init_waitqueue_entry() and async ones with init_waitqueue_func_entry(). The sync/async distinction is used only in prepare_to_wait[_exclusive]() and its only function is to skip setting the current task state if the wait is async. This has a few problems. * No one uses it. None of func_entry users use prepare_to_wait() functions, so the code path never gets executed. * The distinction is bogus. Maybe back when func_entry is used only by aio but it's now also used by epoll and in future possibly by 9p and poll/select. * Taking @state as argument and ignoring it silenly depending on how @wait is initialized is just a bad error-prone API. * It prevents func_entry waits from using wait->private for no good reason. This patch kills is_sync_wait() and the associated code paths from prepare_to_wait[_exclusive](). As there was no user of these code paths, this patch doesn't cause any behavior difference.

2008-10-16vsprintf: use new vsprintf symbolic function pointer formatBjorn Helgaas
Use the '%pF' format to get rid of an "#ifdef DEBUG" and make some printks atomic. This removes the last in-tree uses of print_fn_descriptor_symbol(). I marked print_fn_descriptor_symbol() deprecated and scheduled it for removal next year to give time for out-of-tree modules to be updated. parisc's print_fn_descriptor_symbol() is currently broken there (it needs to dereference the function pointer similar to ia64 and power). This patch shouldn't make anything worse, but it means we need to fix dereference_function_descriptor() instead of print_fn_descriptor_symbol() to get meaningful initcall_debug output.

2008-10-16pm: rework disabling of user mode helpers during suspend/hibernationRafael J. Wysocki
We currently use a PM notifier to disable user mode helpers before suspend and hibernation and to re-enable them during resume. However, this is not an ideal solution, because if any drivers want to upload firmware into memory before suspend, they have to use a PM notifier for this purpose and there is no guarantee that the ordering of PM notifiers will be as expected (ie. the notifier that disables user mode helpers has to be run after the driver's notifier used for uploading the firmware). For this reason, it seems better to move the disabling and enabling of user mode helpers to separate functions that will be called by the PM core as necessary.

A series of patches introduce a generic header file for the software IO/TLB implementation in lib/swiotlb.c. Currently each architecture using this code defines the prototypes itself. The prototypes are moved to include/linux/swiotlb.h and this file is included in architecture specific code for X86 and IA64.

2008-10-14HID: fix a lockup regression when using force feedback on a PID deviceAnssi Hannula
Commit 8006479c9b75fb6594a7b746af3d7f1fbb68f18f introduced a spinlock in input_dev->event_lock, which is locked when handling input events. However, the hid-pidff driver sleeps when handling events as it waits for reports being sent to the device before changing the report contents again. This causes a system lockup when trying to use force feedback with a PID device, a regression introduced in 2.6.24 and 2.6.23.15. Fix it by extracting the raw report data from struct hid_report immediately when hid_submit_report() is called, therefore allowing drivers to change the contents of struct hid_report immediately without affecting the already-queued transfer. In hid-pidff, re-add the removed usbhid_wait_io() to pidff_erase_effect() instead, to prevent a full report queue from causing the submission to fail, thus not freeing up device memory. pidff_erase_effect() is not called while dev->event_lock is held.
