44a04733d4 mm/iob: Don't return NULL in iob_pack
We don't want to get a NULL pointer after iob_pack on an IOB chain with
several iobs with length 0, it should return one IOB with length 0.
Otherwise each place calls iob_pack needs to check the result.

53d4b9ed54 mm/mm_map: Give the mm_map as parameter to the mm_map functions
This way the mappings can be modified for any vm area, not only the
process that is running.

Why? This allows mapping pages to kernel dynamically, this functionality
will be presented later.

81d37d0320 mm_memalign: avoid two adjacent free nodes situation.
Original code assumes the previous node in physical must be
ALLOCED, but other thread may free the previous node between
mm_malloc() and mm_lock(), and the original code didn't condsider
this, which will cause two adjacent free nodes situation and this
should not be happened.

This commit will merge the previous node and node if the previous
node is free to avoid the situation discribed above.
