For s390, we have one of our rocket science virtualization accelerating facilities that limits us to 64 cpus per guest. This may well be extended later on, but for now that would be sufficient. Thinking about Christoph Lameter with his 4k CPU boxes, I believe ia64 would want faaaar more than that.

But the interrupt vector can be encoded in __u64? ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
