Linux 7.2 has landed, dragging x86 timing clean out of the nineties by making the Time Stamp Counter mandatory.

There’s probably a fortunate 500 company running some load bearing server from 20 years ago, that ends up back in production, everytime they fail to migrate the critical service away from it.
There must have been demand to keep x86 32bit alive this long.
I guarantee they aren’t updating that server.
It probably runs payroll and no one is willing to miss a paycheck due to a botched updated
If it’s from 20 years ago then isn’t that like 15 years too new to be affected by this patch?
