DIDMA  is a  new  dynamic memory  allocator  algorithm which  provides
rtl_malloc and rtl_free operations.

DIDMA module operation is:

1) When DIDMA.o is inserted like a module, it reserves a big block
   of memory using "kmalloc" kernel function.
2) After 1) for all RTLinux modules are available rtl_malloc, rtl_free, 
   rtl_realloc, etc...
3) When DIDMA.o is removed, it frees the reserved big block.

DIDMA  uses "bigphysarea" linux  kernel patch  to reserve  the initial
block of memory.
