[kvm-unit-tests PATCH v4 0/9] s390x: Add SIE library and simple tests

[Janosch Frank <frankja@linux.ibm.com>]

This is the absolute minimum needed to run VMs inside the KVM Unit
Tests. It's more of a base for other tests that I can't (yet) publish
than an addition of tests that check KVM functionality. However, I
wanted to decrease the number of WIP patches in my private
branch. Once the library is available maybe others will come and
extend the SIE test itself.

Yes, I have added VM management functionality like VM create/destroy,
etc but as it is not needed right now, I'd like to exclude it from
this patch set for now.

v4:
	* Removed asm directory and moved all asm files into s390x/ (I changed my view)
	* Review fixes
	* Removed a stray newline in the asm offsets file

v3:
	* Rebased on re-license patches
	* Split assembly
	* Now using ICPT_* constants
	* Added read_info asserts
	* Fixed missing spin_lock() in smp.c lib
	* Replaced duplicated code in sie test with generic intercept test
	* Replaced uv-guest.x bit testing with test_bit_inv()
	* Some other minor cleanups
