49d776ffb5 ALSA: pcm: Avoid mmap warnings on x86 
On x86, using dma_mmap_coherent() for the pages allocated via
dma_alloc_coherent() results in a warning like:
  aplay:32536 map pfn RAM range req uncached-minus for [mem 0x21d500000-0x21d51ffff], got write-back

Until the issue is addressed in the core side, take back to the old
good way in PCM code only for x86.

8057727087 Merge branch 'topic/pcm-mmap-cleanup' into for-next 
This drags a few post-3.18 mmap fixes, a cleanup of dma_mmap_coherent()
usages and additional fixups for some architectures.

930352862e Merge branch 'topic/enum-info-cleanup' into for-next 
this is a series of patches to just convert the plain info callback
for enum ctl elements to snd_ctl_elem_info().  Also, it includes the
extension of snd_ctl_elem_info(), for catching the unexpected string
cut-off and handling the zero items.

63825f3a87 ALSA: pcm: Disable mmap for known broken archs 
Some architectures like PARISC is known not to support mmap properly
with the DMA buffer, where dma_mmap_coherent() returns -EINVAL
unconditionally.  From the API POV, we should rather drop the mmap
support there and expose it before the user-space tries to call mmap.

The patch contains again ugly ifdef's, unfortunately, as there is no
global flag indicating this.  Once when such macro is defined, we can
get rid of this instead.

c37de55efa ALSA: pcm: Remove arch-dependent mmap kludges 
Since we have consistently dma_mmap_coherent() for all architectures,
the current ifdef and arch-specific codes in pcm core can be cleaned
up gracefully.

cf6814f2b5 ALSA: ctxfi: remove unused variable 
As of now the pointer to struct dai is not being used anywhere in the
function. So it is safe to remove the variable.
If we are ever doing anything with the container_of(daio, struct dai, daio),
then at that time we can again add the variable.
