I see what you want to do...

Hello Peter,
The cpu-memory and memory have same address space through info mtree tool.
address-space: memory
- (prio 0, i/o): system
-7fff (prio 0, i/o): alias ram-below-4g @pc.ram
-7fff
00

Hello Paolo&peter,
Maybe below patch is much more better, I also did the verification. Please all
of you give some comments, many thanks!

Since cpu-memory and memory have same address space,one malloced
memory is enough. This patch will skip memory malloc for memory
address space,which will reduce around 3M physical memory in heap.
