[PATCH 0/2] ALSA: Clear PCM buffers more properly

[Takashi Iwai]

Hi,

here are two small fix patches for PCM buffer allocations.
Basically those address two things that have been discussed in the
recent thread [1]:
* Clear the remaining bytes in PCM buffer pages that are exposed via
  mmap
* Assure the page aligned allocations for genalloc

This doesn't cover the cases where non-standard PCM buffer allocation
is used.  Those should handle the buffer clearance by themselves.
