This is the patch series to address the issue that kdump 2nd kernel
now fails to wake up multiple CPUs.

This is based on 3.11-rc7.

I tested this patch series on x86. I used 2 cpus by specifying
nr_cpus=2 for the 2nd kernel. I checked both ACPI MADT and MP table
case; the former is default on my system and for the latter I did
acpi=off. I crashed the system both on BSP and AP by taskset -c {0,1}
sh -c "echo c > /proc/sysrq-trigger".
