That scheduler issue doesn't appear in mainline as no one is allocating sparse
node IDs yet.
There is still the opportunity for an Oops with CPUMASK_OFFSTACK and
/sys/.../local_cpus and even with CPUMASK_OFFSTACK disabled it will return
random data.
Ralph has picked up the mips bit, Ben is sucking in the powerpc bit.
Davem has acked the sparc bit. I'll roll up a -stable patch once they
hit.
No answer from alpha and ia64.
Anton
