The nx bit is awkwardly placed in the 63rd bit position; furthermore it has a reversed meaning compared to the other bits, which means we can't use a bitwise and to calculate compounded access masks. So, we simplify things by creating a new 3-bit exec/write/user access word, and doing all calculations in that. Signed-off-by:
