During kdump, two set of NMI IPIs are sent to secondary CPUs, if
'crash_kexec_post_notifiers' option is set. The first set of NMI IPIs
to stop the CPUs and the other set to collect register data. Instead,
capture register data for secondary CPUs while stopping them itself.
Also, fallback to smp_sen
Hi Nick,
Thanks for the review..

Capture register data for secondary CPUs in crash_smp_send_stop()
instead of doing it much later in crash_kexec_prepare_cpus() function
with another set of NMI IPIs to secondary CPUs. This change avoids
unnecessarily tricky post processing of data to get the right
backtrace for these CPUs.
