pushl $SYSENTER_RETURN
SYSENTER_RETURN is a link time constant that is defined based on the
location of the vsyscall page. 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.
