320: <i>i386 architecture</i><br>
1.1 deraadt 321: Change the implementation of i386 W^X so that the "execute line" can move around.
322: Before it was limited to being either at 512MB (below which all code normally
323: lands) or at the top of the stack. Now the line can float as
324: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mprotect&sektion=2">mprotect(2)</a>
325: and
326: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mmap&sektion=2">mmap(2)</a>
327: requests need it to. This is now implemented using only GDT selectors
328: instead of the LDT so that it is more robust as well.
