Revision a5321aec6412b20b5ad15db2d6b916c05349dbff authored by Ashok Raj on 28 February 2018, 10:28:46 UTC, committed by Thomas Gleixner on 08 March 2018, 09:19:26 UTC
Original idea by Ashok, completely rewritten by Borislav. Before you read any further: the early loading method is still the preferred one and you should always do that. The following patch is improving the late loading mechanism for long running jobs and cloud use cases. Gather all cores and serialize the microcode update on them by doing it one-by-one to make the late update process as reliable as possible and avoid potential issues caused by the microcode update.
