Hi,

I am writing a 32-bit user-level task that needs to share a large chunk
of memory (60k) with a device driver.  Since the device driver is
only 16-bit and needs to be able to access the memory regardless of the 
user-level context, the memory needs to be mapped into a global gdt
segment.  I also need the memory mapped into the user-level task's
linear address space.  Does anybody know how to do this?		

Thanks for any information
