Subject: uml: physical memory shouldn't include initial stack
From: Jeff Dike <jdike@xxxxxxxxxxx>
The top of physical memory should be below the initial process stack, not the
top of the address space, at least for as long as the stack isn't known to the
kernel VM system and appropriately reserved.
