I'm having trouble with those checks.. while they're not wrong they're
not correct either. Mostly the top address space is where the kernel
lives and on 32-on-64 compat the boundary is much lower still. Ideally
it'd be TASK_SIZE, but that doesn't work since it assumes you're testing
for the current task.
