It is implemented with vmacll instruction. This still has unfixed stuff from 2 review cycles ago. Thomas corrected this in his review to: "is implemented with the VMCALL instruction" https://lkml.kernel.org/r/alpine.DEB.2.21.1904052110370.1802@nanos.tec.linutronix.de You ignored it. I reminded you about it and suggested to check and incorporate *all* review feedback before sending another version: https://lkml.kernel.org/r/20190408151010.GI15689@zn.tnic You ignored it again. Now, if you get ignored, you know why, right? -- Regards/Gruss, Boris. Good mailing practices for 400: avoid top-posting and trim the reply.
