|| ||[announce] rcu-walk and dcache scaling tree update |

|| ||Article, Thread
I'm rebasing the tree, because I don't expect anybody to be basing
downstream work on it, I hope that doesn't cause anybody pain.
Git tree is here:
Changes since last posting:
* Added mntget/mntput scaling patch. I think this is important for
testers because it significantly increases parallelism through the
dcache and path walk. So both performance and races will get better
* Missing vfs.txt documentation for new _rcu dentry and inode ops.
* Large improvements to Documentation/filesystems/path-walk.txt
* Improved some changelogs
* Added AMD fam10h numbers to ``memcmp optimisation'' changelog, and
Westmere numbers to ``prefetch inode'' optimisation changelog. The
AMD doesn't get such a big boost as the Intel CPU when avoiding rep
cmp, but does get a small improvement.
