How are the patches coming along?

I just hung a machine here while attempting to kexec. It appears to
have onlined all of the secondary threads, and then hung here:

kexec: Waking offline cpu 1.
kvm: enabling virtualization on CPU1
kexec: Waking offline cpu 2.
kvm: enabling virtualization on CPU2
kexec: Waking offline cpu 3.
kvm: enabling virtualization on CPU3
kexec: Waking offline cpu 5.
kvm: enabling virtualization on CPU5
[...]
kvm: enabling virtualization on CPU63
kexec: waiting for cpu 1 (physical 1) to enter OPAL
kexec: waiting for cpu 2 (physical 2) to enter OPAL
kexec: waiting for cpu 3 (physical 3) to enter OPAL

I'm running benh's next branch as of thismorning, and SMT was off.

Could you please post your latest patches a series? I will test them here.

Cheers,

Joel
