| * [ARM] 3160/1: SharpSL: Add driver for Akita specific GPIOsRichard Purdie2005-11-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch from Richard Purdie Add a driver for the extra GPIOs found on the Sharp SL-C1000 (Akita). These GPIOs are found on a Maxim MAX7310 I2C i/o expander chip. A generic GPIO driver for the MAX7310 was attempted but this mini driver is a much simpler and much more effective solution avoiding several issues and complexity the generic driver had (as discussed on LKML). The platform device is required so the device parent can be set correctly which ensures the device is one of the last to suspend and first to resume. Whilst the i2c suspend/resume calls can be influenced, nothing guarantees this is easlier/later than the subsystems the gpios are used on which are all independent of i2c (sound, irda, video/backlight etc.).

* | [PATCH] aio: don't ref kioctx after decref in put_ioctxZach Brown2005-11-131-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | put_ioctx's refcount debugging was doing an atomic_read after dropping its reference when it wasn't the last ref, leaving a tiny race for another freeing thread to sneak into. This shifts the debugging before the ops, uses BUG_ON, and reformats the defines a little. Sadly, moving to inlines increased the code size but this change decreases the code size by a whole 9 bytes :) Signed-off-by: Zach Brown <zach.brown@oracle.com> Cc: Benjamin LaHaise <bcrl@kvack.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* | [PATCH] aio: remove kioctx from mm_structZach Brown2005-11-133-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sync iocbs have a life cycle that don't need a kioctx. Their retrying, if any, is done in the context of their owner who has allocated them on the stack. The sole user of a sync iocb's ctx reference was aio_complete() checking for an elevated iocb ref count that could never happen. No path which grabs an iocb ref has access to sync iocbs. If we were to implement sync iocb cancelation it would be done by the owner of the iocb using its on-stack reference. Removing this chunk from aio_complete allows us to remove the entire kioctx instance from mm_struct, reducing its size by a third. On a i386 testing box the slab size went from 768 to 504 bytes and from 5 to 8 per page.

* | [PATCH] m68k: convert thread flags to use bit fieldsRoman Zippel2005-11-131-34/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove task_work structure, use the standard thread flags functions and use shifts in entry.S to test the thread flags. Add a few local labels to entry.S to allow gas to generate short jumps. Finally it changes a number of inline functions in thread_info.h to macros to delay the current_thread_info() usage, which requires on m68k a structure (task_struct) not yet defined at this point.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | new helper - task_thread_info(task). On platforms that have thread_info allocated separately (i.e. in default case) it simply returns task->thread_info. m68k wants (and for good reasons) to embed its thread_info into task_struct. So it will (in later patch) have task_thread_info() of its own. For now we just add a macro for generic case and convert existing instances of its body in core kernel to uses of new macro. Obviously safe - all normal architectures get the same preprocessor output they used to get.

The problem is most simply explained with an example: If we find a pgd is clear, we still have to call into unmap_page_range PGDIR_SIZE / ZAP_BLOCK_SIZE times, each time checking the clear pgd, in order to progress the working address to the next pgd. The fundamental way to solve the problem is to keep track of the end address we've processed and pass it back to the higher layers. From: Nick Piggin <npiggin@suse.de> Modification to completely get away from address based work estimate and instead use an abstract count, with a very small cost for empty entries as opposed to present pages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The file_lock spinlock sits close to mostly read fields of 'struct files_struct' In SMP (and NUMA) environments, each time a thread wants to open or close a file, it has to acquire the spinlock, thus invalidating the cache line containing this spinlock on other CPUS. So other threads doing read()/write()/... calls that use RCU to access the file table are going to ask further memory (possibly NUMA) transactions to read again this memory line. Move the spinlock to another cache line, so that concurrent threads can share the cache line containing 'count' and 'fdt' fields. It's worth up to 9% on a microbenchmark using a 4-thread 2-package x86 machine.

We had similar problems with other ioctls where userspace did things like that. What we did there was to put the compat handler to generic code. The patch below does that, adding a big comment about what's going on and removing the COMPAT_IOCTL entires for these on powerpc that not only weren't ever useful but are duplicated now aswell.

ABC is a way of counting bytes ack'd rather than packets when updating congestion control. The orignal ABC described in the RFC applied to a Reno style algorithm. For advanced congestion control there is little change after leaving slow start. Signed-off-by: Stephen Hemminger <shemminger@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A nice feature of sysfs is that it can create the symlink from the driver to the module that is contained in it. It requires that the device_driver.owner is set, what is not the case for many PCI drivers. This patch allows pci_register_driver to set automatically the device_driver.owner for any PCI driver. Credits to Al Viro who suggested the method.

* | | | | | | [PATCH] pciehp: request control of each hotplug controller individuallyrajesh.shah@intel.com2005-11-101-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tweaks the way pciehp requests control of the hotplug hardware from BIOS. It now tries to invoke the ACPI _OSC method for a specific hotplug controller only, rather than walking the entire acpi namespace invoking all possible _OSC methods under all host bridges. This allows us to gain control of each hotplug controller individually, even if BIOS fails to give us control of some other hotplug controller in the system.
