Merge tag 'parisc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/parisc-2.6
Pull PARISC changes from James Bottomley:
"This is a couple of high code motion patches (all within arch/parisc)
I'd like to apply at -rc1 to avoid conflicts with anything else. One
moves us on to the generated instead of included asm file model and
the other is a pull request from David Howells for UAPI
disintegration.
Signed-off-by: James Bottomley <JBottomley@Parallels.com>"
