Subject: [V4 PATCH 0/3] Minor improvements to the selftest setup logic

This series is posted in context of the discussion at:
https://lore.kernel.org/lkml/Ywa9T+jKUpaHLu%2Fl@google.com/

Major changes:
1) Move common startup logic to a single function in kvm_util.c
2) Introduce following APIs:
	kvm_selftest_arch_init: to perform arch specific common startup.
	kvm_arch_vm_post_create: to perform arch specific common setup
		after VM creation.

Changelog
=========
v4:
* Removed the patch to precompute cpu type, will be introduced as part of
  a separate series in future.
v3:
* Original series is split into two and this v3 version contains the
  improvements to selftest and VM setup.
  * Planning to upload the second series to execute hypercall
    instruction according to cpu type separately.
* Addressed comments from David and Sean.
