Do not call hw_mds_recalculate() from initializecpu().
If MDS mitigation is enabled by the tunable but MDS microcode is not
early-loaded, software mitigation is selected. This causes
initializecpu() to try to allocate memory which makes boot process
very unhappy.
Create SYSINIT that runs sufficiently late to succeed.
