echo used > /proc/memdump //output all used memory info with backtrace
echo free > /proc/memdump //output all free memory info

aa43a0215d mm: fix memory corruption when loop create/exit thread in SMP mode 
Root casue:
when do thread exit, need add free stack operation to mm_delaylist,
but in SMP mode, CPU0 thread1 exit, at this time, CPU1 call malloc
and free mm_delaylist.

Fix:
Divide mm_delaylist for per CPU in SMP mode.

85f0bc591e mm:initialize ensure alignment. 
Broken by 635cfa.

   On an stm32 the heap is formed from
   const uintptr_t g_idle_topstack = HEAP_BASE;
   where HEAP_BASE is &_bss + CONFIG_IDLE_STACKSIZE.

   Both these values are not deterministic. One
   comes from the compiler, the other the system
   configurator.

   a 3 byte bss and 250 byte stack would lead to
   and unaligned address used as the heap to be.

   The compiler used clever `strd r1,r3,[r5,#8]` to
   store 2 values in one memory cycle into the
   heap_impl struct. Resulting in a hardfault.

   Change the amount of bss or the CONFIG_IDLE_STACKSIZE
   could lead to a non-functional NuttX system.

a4e0b23f4f Prevents NuttX crashing if MM_REGIONS is too small. 
Added a DEBUGASSERT and a runtime check so that mm_region will not overwrite critical heap data if user incorrectly defines MM_REGIONS.
