[PATCH 1/2] gpiolib: get rid of struct poll_desc and worklet
As sysfs_notify_dirent has been made irq safe, there is no reason to not call it directly from irq. With the work_struct removed, the remaining element in poll_desc is a sysfs_dirent pointer which may not be NULL. We can therefore store it directly in the idr and pass it as context to the irq handler. Most part ... 9 Jul 2010 16:06

[PATCH 2/2] gpiolib: allow nested threaded irqs for poll(2)
The pca953x driver requires the use of threaded irqs as its irq demultiplexer can sleep. Our irq handler can be called from any context, so use request_any_context_irq to allow threaded irqs as well.

[S+Q2 03/19] percpu: allow limited allocation before slab is online
This patch updates percpu allocator such that it can serve limited amount of allocation before slab comes online. This is primarily to allow slab to depend on working percpu allocator. Two parameters, PERCPU_DYNAMIC_EARLY_SIZE and SLOTS, determine how much memory space and allocation map slots are reserved. If ... 9 Jul 2010 16:06

[S+Q2 12/19] slub: Dynamically size kmalloc cache allocations
kmalloc caches are statically defined and may take up a lot of space just because the sizes of the node array has to be dimensioned for the largest node count supported. This patch makes the size of the kmem_cache structure dynamic throughout by creating a kmem_cache slab cache for the kmem_cache objects. The boo... 9 Jul 2010 16:06

[S+Q2 11/19] slub: Remove static kmem_cache_cpu array for boot
The percpu allocator can now handle allocations in early boot. So drop the static kmem_cache_cpu array.

[S+Q2 16/19] slub: Resize the new cpu queues
Allow resizing of cpu queue and batch size. This is done in the basic steps that are also followed by SLAB. The statically allocated per cpu areas are removed since the per cpu allocator is already available when kmem_cache_init is called. We can dynamically size the per cpu data during bootstrap.
