Thanks!  I'm not using SGI UV and I'm not using kexec, so I guess I
sidestepped most of those issues.  Greg, I think we need to unrevert
the cpa->pfn change (otherwise the L1TF fix probably gets pretty
messy) and I guess pull in the other patches that Ben mentions.

Ok, so what patch should be reverted?  I'm seeing other reports of
problems all around this same area, but I can't figure out exactly what
to do.

Guenter, any ideas?

thanks,
