(39fe2fc96694 "selftests: kvm: make allocation of extra memory take effect")
changed the meaning of extra_mem_pages and treated it as slot0 memory size.
In fact extra_mem_pages is used for non-slot0 memory size, there is no custom
slot0 memory size support. See discuss in https://urldefense.com/v3/__https://lkml.org/lkml/2021/6/3/551__;!!GqivPVa7Brio!K2FcwkE2nzlPAWgBHh6o6jtaWe66RMlfkb-b_8mAtVa5d8ez_sArupY-EqIquuCj2sorww$
for more details.
This patchset restores extra_mem_pages's original meaning and adds support for
custom slot0 memory with a new parameter slot0_mem_pages.
Run below command, all 39 tests passed.
