21956b61f5 ALSA: ctxfi - fix PTP address initialization 
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.

cd391e206f ALSA: ctxfi - Remove PAGE_SIZE limitation 
Remove the limitation of PAGE_SIZE to be 4k by defining the own
page size and macros for 4k.  8kb page size could be natively supported,
but it's disabled right now for simplicity.

Also, clean up using upper_32_bits() macro.

Replace a spinlock with a mutex protecting the vm block list at
mmap / munmap calls, which caused Oops like below:
