NAME
       snd_pcm_lib_alloc_vmalloc_32_buffer - allocate 32-bit-addressable buffer

ARGUMENTS
       substream
	   the substream to allocate the buffer to

       size
	   the requested buffer size, in bytes

DESCRIPTION
       This function works like snd_pcm_lib_alloc_vmalloc_buffer, but uses vmalloc_32, i.e., the pages are allocated from 32-bit-addressable
       memory.
