enable_sep_cpuSet up the CPU state needed to execute SYSENTER/SYSEXIT instructions* on 32-bit kernels:
cpu_initpu_init() initializes state that is per-CPU. Some data is already* initialized (naturally) in the bootstrap process, such as the GDT* and IDT. We reload them nevertheless, this function acts as a* 'CPU state barrier', nothing should get across.
