Hi,
I kinda vaguely remember seeing a patch while ago to support 128
physical cpus by hypervisor, I believe it was from Jan B. Now looking
for it i'm unable to find it, i only see HVM vcpu patch for 128 vcpus
in my search.
Firstly, is it OK to increase NR_CPUS to 128, and secondly is it ok to
do so in 3.4.3-rc2-pre tree, or is it 4.0 only?
thanks much,
mukesh

It should work fine on both 3.4 and 4.0.

unfortunately, i'm not allowed to disclose since it's a pre-release.
but the hardware vendor will announce soon.
HT makes it 128 for xen btw.
