Well, even if you did remap PTEs (TLBs are N/A), or claimed that special memory, that may be too late. The kernel might've already allocated and stomped over it. A reliable way is to redefine the kernel's "memory map" which takes effect during boot. Look for the memory map as a .h in arch/ (IIRC). -- Jim Brooks __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
