MSA6 is a prereq, no?
MSA6 is the prereq. However, there is no explicit feature definition
for the MSA_EXT_6 due to no STFLE and subfunctions only. The only
way would be to pick one or more / all MSA6 subfunctions for which
there is a feature defined...
Which you did for MSA11, no?
The other way around.
Here: MSA_EXT_12 would check/have a dependency on all(?) subfuncs
introduced with MSA_EXT_6.
I'm not saying that subfunc handling is great :)
Let me have a look which functions come with MSA_6 related to KIMD/KLMD.
Would it be OK to have those checks as a separate patch so that cpu
model in general is not blocked?
