mmap question

	I'd like to mark some virtual address ranges as unusable in the
kernel, too hard to explain why. I'm using the following do_mmap call to
do this but it seems to die accessing address 0x100.

error = do_mmap(NULL, ARMPID_TASK_SIZE - (1 << 20), PAGE_SIZE, PROT_NONE,
                MAP_FIXED | MAP_PRIVATE, 0);

Is this the correct way to allocate an untouchable region of PAGE_SIZE at
(ARMPID_TASK_SIZE - (1 << 20))?

	Cheers, Adam
