As I understand it: KPTI prevents Meltdown attack on x86-64, but
Spectre means even x86-64 is not expected to be safe?

Ok, so Meltdown is public... And I still have some nice 32-bit
machines I'd like to keep working.

Proof of concept is out, https://github.com/IAIK/meltdown/ .

Is anyone working on KPTI for x86-32? SLES11 should still be
supported, and that should have x86-32 version; any chance SUSE can
share some patches?

Thanks,
									Pavel
