    ALSA: ctxfi - fix PTP address initialization · 21956b61
    Jaroslav Kysela authored
    After hours of debugging, I finally found the reason why some source
    and runtime combination does not work. The PTP (page table pages)
    address must be aligned. I am not sure how much, but alignment to
    PAGE_SIZE is sufficient. Also, use ALSA's page allocation routines
    to ensure proper virtual -> physical address translation.
