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
