Yeah :-)
On a related note, now that these bits are upstream, what are your
rough plans for doing the int81 vsyscall emulation patch?
The int81 patch would actually be (much!) more important to the
average Linux user than getting rid of the vsyscall from static
binaries: the vsyscall is the last predictable executable address in
PIE daemons with a dangerous SYSENTER instruction in it ...
I'd actually consider accelerating it into v2.6.40.
Thanks,
Ingo
