and one more question - is there a way to revert patch?
I've accidentally updated bios with this microcode through lenovo update center.
I doubt this vulnerability will ever affect my work with x230 so do not want to lose in performance.

There is a way to flash older BIOS, but not through Lenovo's official tool. I never tried, but I know some folks here have the know-how.
