Merge branch 'topic/memalloc-cleanup' into for-next

ALSA: Drop hackish GFP giveaway for CONTINUOUS pages

This is a series of cleanup patches for dropping the current hackish
way of passing the GFP_* flags for CONTINOUS and VMALLOC memory
allocations.  There are only three users for this legacy feature, and
all of them seem superfluous.  And, if any driver requires the memory
restriction in future, it can now pass the proper device pointer for
specifying the DMA mask.
