You need to call register_cpu_notifier() from your init function.
Init functions could be of two types:
1. early init (init function called when only the boot processor is online).
2. late init (init function called _after_ all the CPUs are online).
In your init function,
For the first case, you should add the following to your init function
register_cpu_notifier(&foobar_cpu_notifier);
For the second case, you should add the following to your init function
register_hotcpu_notifier(&foobar_cpu_notifier);
You can fail PREPARE notifiers if something doesn't work to prepare resources.
This will stop the activity and send a following CANCELED event back.

initrd is mounted as root, and the normal boot procedure is followed,
with the RAM disk still mounted as root.
Compressed cpio images
----------------------
Recent kernels have support for populating a ramdisk from a compressed cpio
archive, on such systems, the creation of a ramdisk image doesn't need to
involve special block devices or loopbacks, you merely create a directory on
disk with the desired initrd content, cd to that directory, and run (as an
example):
find . | cpio --quiet -c -o | gzip -9 -n > /boot/imagefile.img
Examining the contents of an existing image file is just as simple:
mkdir /tmp/imagefile
cd /tmp/imagefile
gzip -cd /boot/imagefile.img | cpio -imd --quiet
