2008-08-13usb: musb: pass configuration specifics via pdataFelipe Balbi
Use platform_data to pass musb configuration-specific details to musb driver. This patch will prevent that other platforms selecting HAVE_CLK and enabling musb won't break tree building. The other parts of it will come when linux-omap merge up more omap2/3 board-files.

2008-08-13usb-serial: don't release unregistered minorsAlan Stern
This patch (as1121) fixes a bug in the USB serial core. When a device is unregistered, the core will give back its minors -- even if the device hasn't been assigned any! The patch reserves the highest minor value (255) to mean that no minor was assigned. It also removes some dead code and does a small style fixup.

2008-08-14CRED: Introduce credential access wrappersDavid Howells
The patches that are intended to introduce copy-on-write credentials for 2.6.28 require abstraction of access to some fields of the task structure, particularly for the case of one task accessing another's credentials where RCU will have to be observed. Introduced here are trivial no-op versions of the desired accessors for current and other tasks so that other subsystems can start to be converted over more easily. Wrappers are introduced into a new header (linux/cred.h) for UID/GID, EUID/EGID, SUID/SGID, FSUID/FSGID, cap_effective and current's subscribed user_struct. These wrappers are macros because the ordering between header files mitigates against making them inline functions. linux/cred.h is #included from linux/sched.h. Further, XFS is modified such that it no longer defines and uses parameterised versions of current_fs[ug]id(), thus getting rid of the namespace collision otherwise incurred.

2008-08-13[XFS] extend completions to provide XFS object flush requirementsDavid Chinner
XFS object flushing doesn't quite match existing completion semantics. It mixed exclusive access with completion. That is, we need to mark an object as being flushed before flushing it to disk, and then block any other attempt to flush it until the completion occurs. We do this but adding an extra count to the completion before we start using them. However, we still need to determine if there is a completion in progress, and allow no-blocking attempts fo completions to decrement the count. To do this we introduce: int try_wait_for_completion(struct completion *x) returns a failure status if done == 0, otherwise decrements done to zero and returns a "started" status. This is provided to allow counted completions to begin safely while holding object locks in inverted order. int completion_done(struct completion *x) returns 1 if there is no waiter, 0 if there is a waiter (i.e. a completion in progress). This replaces the use of semaphores for providing this exclusion and completion mechanism.

2008-08-12seq_file: add seq_cpumask(), seq_nodemask()Alexey Dobriyan
Short enough reads from /proc/irq/*/smp_affinity return -EINVAL for no good reason. This became noticed with NR_CPUS=4096 patches, when length of printed representation of cpumask becase 1152, but cat(1) continued to read with 1024-byte chunks. bitmap_scnprintf() in good faith fills buffer, returns 1023, check returns -EINVAL. Fix it by switching to seq_file, so handler will just fill buffer and doesn't care about offsets, length, filling EOF and all this crap. For that add seq_bitmap(), and wrappers around it -- seq_cpumask() and seq_nodemask().

2008-08-12modules: extend initcall_debug functionality to the module loaderArjan van de Ven
The kernel has this really nice facility where if you put "initcall_debug" on the kernel commandline, it'll print which function it's going to execute just before calling an initcall, and then after the call completes it will 1) print if it had an error code 2) checks for a few simple bugs (like leaving irqs off) and 3) print how long the init call took in milliseconds. While trying to optimize the boot speed of my laptop, I have been loving number 3 to figure out what to optimize... ... and then I wished that the same thing was done for module loading. This patch makes the module loader use this exact same functionality; it's a logical extension in my view (since modules are just sort of late binding initcalls anyway) and so far I've found it quite useful in finding where things are too slow in my boot.

2008-08-12intel/agp: rewrite GTT on resumeKeith Packard
On my Intel chipset (965GM), the GTT is entirely erased across suspend/resume. This patch simply re-plays the current mapping at resume time to restore the table.=20 I noticed this once I started relying on persistent GTT mappings across VT switch in our GEM work -- the old X server and DRM code carefully unbind all memory from the GTT on VT switch, but GEM does not bother. I placed the list management and rewrite code in the generic layer on the assumption that it will be needed on other hardware, but I did not add the rewrite call to anything other than the Intel resume function. Keep a list of current GATT mappings. At resume time, rewrite them into the GATT. This is needed on Intel (at least) as the entire GATT is cleared across suspend/resume.
