Pull x86 microcode updates from Thomas Gleixner: - Disable late microcode loading by default. Unless the HW people get their act together and provide a required minimum version in the microcode header for making a halfways informed decision its just lottery and broken. - Warn and taint the kernel when microcode is loaded late - Remove the old unused microcode loader interface - Remove a redundant perf callback from the microcode loader * tag 'x86-microcode-2022-06-05' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/microcode: Remove unnecessary perf callback x86/microcode: Taint and warn on late loading x86/microcode: Default-disable late loading x86/microcode: Rip out the OLD_INTERFACE
