A revised version of the dropped IBRS-firmware patch which now just ignores the horrid hpwdt driver completely, and explicitly disables preemption while IBRS is set. Revised version of the IBRS_ALL patch with a typo fixed, revert another broken bikeshedding patch, and add support for retpoline builds with clang now that clang is fixed.
