    Subject[PATCH 113/208] x86/fpu: Call fpu__init_cpu_ctx_switch() from fpu__init_cpu()
    Date
    fpu__init_cpu() is currently called from fpu__init_system(),
    which is the wrong place for it: call it from the proper high level
    per CPU init function, fpu__init_cpu().

    Note, we still keep the old call site as well, because it depends
    on having proper CR0::TS setup. We'll fix this in the next patch.
