Marcos Del Sol Vives 639475d434 x86/CPU: Add support for Vortex CPUs ... DM&P devices were not being properly identified, which resulted in unneeded Spectre/Meltdown mitigations being applied. The manufacturer states that these devices execute always in-order and don't support either speculative execution or branch prediction, so they are not vulnerable to this class of attack. [1] This is something I've personally tested by a simple timing analysis on my Vortex86MX CPU, and can confirm it is true. Add identification for some devices that lack the CPUID product name call, so they appear properly on /proc/cpuinfo. ¹https://www.ssv-embedded.de/doks/infos/DMP_Ann_180108_Meltdown.pdf [ bp: Massage commit message. ] Signed-off-by: Marcos Del Sol Vives <marcos@orca.pet> Signed-off-by: Borislav Petkov <bp@suse.de> Link: https://lkml.kernel.org/r/20211017094408.1512158-1-marcos@orca.pet		2021-10-21 15:49:07 +02:00
