It needs to be aligned to a multiple of getpagesize(), AFAIK. But,
more importantly, I've heard it mentioned that POSIX.1b says
mprotect() can only be used on memory that has been obtained from
mmap().
Also, AFAIK, there is no munprotect(). The default state of memory is
read/write, so you'd call mprotect() with PROT_READ|PROT_WRITE.
