Subject: [PATCH 0/2] reducing memory footprint of ALSA

We are planning to work on reducing memory footprint of ALSA,
targeting on small memory embedded devices(e.g. IoT), this
series focuses on disabling procfs, hw/sw params refinement,
mmap, dpcm, dapm, compressed API, compat code APIs...

These first two patches is a start, add config menu in Kconfig,
and disable ALSA proc FS once reducing memory footprint is
selected, which can save about 9KB code size on x86_64 platform.

Comments are welcomed.
