SRU Justification:
Impact: When using VMs with many CPUs on kvm, the module is loaded per CPU which can cause allocation failures.

Fix: 8d8022e8aba85192e937f1f0f7450e256d66ae5c solves the issue which is present in 3.8 series and beyond.

Testcase: Boot a VM with many CPUs, reboot and check if issue occurs.

Rusty Russell (1):
  module: do percpu allocation after uniqueness check.  No, really!
