This topic has a very long history. It comes from Mahesh Salgaonkar <mahesh at 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
