By an "AMD push" do you mean Intel should post a superior implementation a year before AMD does? ;) https://lore.kernel.org/lkml/20210205151631.43511-1-kirill.

BTW, MPX was clearly not the right thing. Nobody really wanted it. The world would be a better place if these address-bit-ignoring things (ARM TBI, AMD UAI, Intel LAM) had been implemented years ago instead all the effort spent on MPX. Believe me, I know. I put a lot of blood, sweat and tears into MPX for Linux. Disclaimer: If you didn't figure it out by now, I work on Linux at Intel.
