Since you're simply removing one addition, in a path that gets executed only once in a kernel boot life, that's not even going to improve performance at all... Right now, I'm more for dropping this change than keeping it.

Hi Matthias Sir, This addition is for indicating vmax value is increased by dvt_fixed. Please keep this information to make it be seen. Many thanks. Sincerely, Roger Lu.
