If the vsyscall page can move, this can not be a constant.The vsyscall page is at PAGE_OFFSET - 2*PAGE_SIZE. It doesn't move. At least not at runtime. At compile time it can change with the new VMSPLIT config options, but that isn't a problem ;) Okay, I get it now. Thanks for the explanation. This certainly does simplify the problem.
