Merge branch 'mm-pat-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull dma_*_writecombine rename from Ingo Molnar:
"Rename dma_*_writecombine() to dma_*_wc()
This is a tree-wide API rename, to move the dma_*() write-combining
APIs closer in name to their usual API families. (The old API names
are kept as compatibility wrappers to not introduce extra breakage.)
The patch was Coccinelle generated"
* 'mm-pat-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
