2009-06-16mm: remove CONFIG_UNEVICTABLE_LRU config optionKOSAKI Motohiro
Currently, nobody wants to turn UNEVICTABLE_LRU off. Thus this configurability is unnecessary.

2009-06-16videobuf-dma-contig: zero copy USERPTR supportMagnus Damm
Since videobuf-dma-contig is designed to handle physically contiguous memory, this patch modifies the videobuf-dma-contig code to only accept a user space pointer to physically contiguous memory. For now only VM_PFNMAP vmas are supported, so forget hotplug. On SuperH Mobile we use this with our sh_mobile_ceu_camera driver together with various multimedia accelerator blocks that are exported to user space using UIO. The UIO kernel code exports physically contiguous memory to user space and lets the user space application mmap() this memory and pass a pointer using the USERPTR interface for V4L2 zero copy operation. With this approach we support zero copy capture, hardware scaling and various forms of hardware encoding and decoding.

2009-06-16page allocator: do not check NUMA node ID when the caller knows the node is ↵Mel Gorman
valid Callers of alloc_pages_node() can optionally specify -1 as a node to mean "allocate from the current node". However, a number of the callers in fast paths know for a fact their node is valid. To avoid a comparison and branch, this patch adds alloc_pages_exact_node() that only checks the nid with VM_BUG_ON(). Callers that know their node is valid are then converted.

The bug is caused by | the following code in drivers/firmware/memmap.c, the resource_size_t is 32bit | variable in 32bit OS, the BUG_ON() will be invoked to result in the Int 6 | error.

2009-06-16time: move PIT_TICK_RATE to linux/timex.hArnd Bergmann
PIT_TICK_RATE is currently defined in four architectures, but in three different places. While linux/timex.h is not the perfect place for it, it is still a reasonable replacement for those drivers that traditionally use asm/timex.h to get CLOCK_TICK_RATE and expect it to be the PIT frequency. Note that for Alpha, the actual value changed from 1193182UL to 1193180UL. This is unlikely to make a difference, and probably can only improve accuracy. There was a discussion on the correct value of CLOCK_TICK_RATE a few years ago, after which every existing instance was getting changed to 1193182. According to the specification, it should be 1193181.818181...

Changeset 1589a993f074124c3edfff03656e910bb472eeaa broke user visible names of flexcop-pci devices, as it did reorder the enum of card types, but did not adjust the array containing the card names. Reorder the names, and uses [FC_AIR_DVBT] = "Air2PC/AirStar 2 DVB-T" assignment style for more clarity. It also adds the revision Number to the name for SkyStar rev. 2.3 and rev 2.6 as I think it is useful to see in log output.

This make status update much faster, and reduce various operation time (UHF scan now takes 15s instead of 2m).
