Subject: [PATCH] rules: move cpu hotplug rule to separate file
In kdump initrd we don't want to automatically bring online all
available CPUs. Hence, kdump maintainers can easily mask the rule by
placing symlink to /dev/null with the same name in /etc/udev/rules.d
RHEL-only
Related: #1266322
[msekleta: note that this is just part of the fix for #1266322, in
order to fix the bug it is necessary to actually mask the newly added
rule when generating kdump initrd]
