KVM: s390: add kselftests

This is the initial implementation for KVM selftests on s390.

tests: kvm: Check for a kernel warning

2019-06-19T14:11:54+00:00

When running with /sys/module/kvm_intel/parameters/unrestricted_guest=N,
test that a kernel warning does not occur informing us that
vcpu->mmio_needed=1.  This can happen when KVM_RUN is called after a
triple fault.
This test was made to detect a bug that was reported by Syzkaller
(https://groups.google.com/forum/#!topic/syzkaller/lHfau8E3SOE) and
fixed with commit bbeac2830f4de ("KVM: X86: Fix residual mmio emulation
request to userspace").

KVM: selftests: enable pgste option for the linker on s390

2019-06-04T12:05:38+00:00

To avoid testcase failures we need to enable the pgstes. This can be
done with /proc/sys/vm/allocate_pgste or with a linker option that
creates an  S390_PGSTE program header.

KVM: selftests: Move kvm_create_max_vcpus test to generic code

2019-06-04T12:05:38+00:00

There is nothing x86-specific in the test apart from the VM_MODE_P52V48_4K
which we can now replace with VM_MODE_DEFAULT. Thus let's move the file to
the main folder and enable it for aarch64 and s390x, too.

KVM: selftests: Add the sync_regs test for s390x

2019-06-04T12:05:38+00:00

The test is an adaption of the same test for x86. Note that there
are some differences in the way how s390x deals with the kvm_valid_regs
in struct kvm_run, so some of the tests had to be removed. Also this
test is not using the ucall() interface on s390x yet (which would need
some work to be usable on s390x), so it simply drops out of the VM with
a diag 0x501 breakpoint instead.

Pull KVM fixes from Paolo Bonzini:
 "The usual smattering of fixes and tunings that came in too late for
  the merge window, but should not wait four months before they appear
  in a release.

  I also travelled a bit more than usual in the first part of May, which
  didn't help with picking up patches and reports promptly"

KVM: selftests: Compile code with warnings enabled

2019-05-24T19:27:05+00:00

So far the KVM selftests are compiled without any compiler warnings
enabled. That's quite bad, since we miss a lot of possible bugs this
way. Let's enable at least "-Wall" and some other useful warning flags
now, and fix at least the trivial problems in the code (like unused
variables).
