73f506b65f mempool: safe memdump for smp, if syslog will switch context 
remove alist, switch to a convenient way to traverse
the physical address directly.

At the same time, we can use `gurad` to mark whether
it is free or alloc or out of bounds check

5c0a5a6627 mm/mempool: support memalign about mempool and mulitple mempool 
The memalign is special to multiple mempool because multiple mempool
doesn't support split and shrink chunk operate. So When you alloc a
memory block and find an aligned address in this block, you need to
occupy 8 bytes before the address to save the address of the padding
size and pool to ensure correct use in realloc and free operations.
So we will use bit1 in the previous address of the address to represent
that it is applied by memalign.
