[merged mm-stable] usb-cdns2-dont-use-gfp_dma-when-calling-dma_alloc_coherent.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: usb: cdns2: don't use GFP_DMA when calling dma_alloc_coherent()
has been removed from the -mm tree.  Its filename was
     usb-cdns2-dont-use-gfp_dma-when-calling-dma_alloc_coherent.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

dma_alloc_coherent() allocates the DMA buffer with the device's
addressing limitation in mind; the DMA core picks the zone from the
device's coherent DMA mask and ignores GFP_DMA passed by the caller.
Use GFP_KERNEL instead so the allocation may reclaim as usual for
probe-time allocations.
