CVE: NA

--------------

System cann't use the cdm nodes memory, but it can mmap all nodes huge
pages, so it will cause Bus error when mmap succeed but the huge pages
were not enough.

When set the cdmmask, users will transfer the numa id by mmap flag to
map the specific numa node hugepages, if there was not enough hugepages
on this node, return -ENOMEM.

Dvpp use flags MAP_CHECKNODE to enable check node hugetlb.
The global variable numanode will cause the mmap not be
reenterable, so use the flags BITS[26:31] directly.
