20041212 Clear ebp on sysenter return

A small information leak was found by Brad Spengler, but it isn't thought to be
useful for exploitation. Since this was fixed in FC* adding a tracking bug for EL4.
Fixed in 2.6:
this patch is bogus for rhel4 since we don't enable sysenter at all.
we do if we run 32bit OS on a CPU with NX.
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
