apply_alternatives and cpu hotplug

Regarding kernel version 2.6.38.8. When a module is loaded apply_alternatives() is called which patches the module code with instructions from the ELF headers of the module. It is my understanding that these instructions are generally CPU optimizations based on the capabilities of the CPU. However, I notice that native_cpu_up() does not call apply_alternatives(). So is it assumed that the CPU capabilities will not change on CPU hotplug? Thank you, Dannie -- Dannie M. Stanley
