So just write this down to some patch that starts adding SMX things. Link: https://cdrdv2.intel.com/v1/dl/getContent/776648 So link and document, and other stuff above is not relevant from upstream context, only potential maintenance burden :-) For any architectures dig a similar fact: 1. Is not dead. 2. Will be there also in future. Make any architecture existentially relevant for and not too much coloring in the text that is easy to check. It is nearing 5k lines so you should be really good with measured facts too (not just launch) :-) BR, Jarkko _______________________________________________ kexec mailing list kexec@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/kexec
