Hello,

I'm booting some latest kernels on a Fedora 11 (released June 2009)
guest.  After the recent change of default to vsyscall=emulate, the
guest fails to boot (init segfaults).

I also tried vsyscall=none, as suggested by hpa, and that fails as
well.  Only vsyscall=native works fine.

The commit that introduced the kernel parameter,

3ae36655b97a03fa1decf72f04078ef945647c1a

is bad too.

The host system is RHEL6, if that matters.

Please let me know if you need any more information or testing.
