Maintainers, ping? Any comment?

This topic has a very long history. It comes from Mahesh Salgaonkar [off-list ref]
For v3: https://patchwork.ozlabs.org/patch/834860/
I hope we can acquire it for "kexec -p" soon.

V4->V5:
   improve the [1/3] implementation based on Benjamin's suggestion.

Mahesh Salgaonkar (1):
   ppc64 boot: Wait for boot cpu to show up if nr_cpus limit is about to
     hit.

Pingfan Liu (2):
   powerpc, cpu: partially unbind the mapping between cpu logical id and
        its seq in dt
   powerpc, cpu: handling the special case when boot_cpuid greater than
     nr_cpus
