Exec from Memory

["Maurice Turcotte" <turcotte@broadcom.com>]

Greetings:

I have a hypothetical linux-mips question posed by a colleage.

Suppose there is no file system available, since there is no disk. And
suppose that I had the capability to place an elf file in a known location
in memory. How would I execute it? It seems like exec really wants a file
name. BTW, this needs to run in use space, not kernel.

Any helpful pointers? Is there a FAQ that might address this?
