This topic has a very long history. It comes from Mahesh Salgaonkar <mahesh@linux.vnet.ibm.com>
For v3: https://patchwork.ozlabs.org/patch/834860/
In this series, I separate and change the mapping between cpu logical id and hwid.
I hope we can acquire it for "kexec -p"

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
