What is the address space layout of 64-bit applications on x86_64? Is the address space below 4GB reserved for kernel mappings?

It's my recollection that, on EM64T systems the 64-bit user process memory map leaves the virtual range 0-0xffffffff unmapped as a mechanism for catching application (and originally kernel) bugs.

Thanks.. for verifying this. Sick hacks, here I come. Sigh.. Drew _______________________________________________ Do not post admin requests to the list. They will be ignored.
