Subject: [PATCH 00/13] KVM monolithic v3

Hello,

Here's the rebase of KVM monolithic on 5.4-rc6 after improving the
Kbuild as suggested in the v2 review.

This should have corrected also the non-x86 KVM builds (not verified
so it may not have full coverage yet, but I should have fixed all
issues reported by kbot so far).

The effect of the patchset is visible at the end of the below pdf. I
dropped CPUID so the results are still an exact match only for the
last two bench slides which are the only important ones in real life.
