Subject: [PATCH v3 0/8] Use TAP in some more x86 KVM selftests

Basic idea of this series is now to use the kselftest_harness.h
framework to get TAP output in the tests, so that it is easier
for the user to see what is going on, and e.g. to be able to
detect whether a certain test is part of the test binary or not
(which is useful when tests get extended in the course of time).

Since most tests also need a vcpu, we introduce our own macros
to define such tests, so we don't have to repeat this code all
over the place.

v3:
- Add patch from Sean to allow setting vCPU's entry points seperately
- Let each test define the entry point via KVM_ONE_VCPU_TEST(), don't
  do it globally from KVM_ONE_VCPU_TEST_SUITE()

v2:
- Dropped the "Rename the ASSERT_EQ macro" patch (already merged)
- Split the fixes in the sync_regs_test into separate patches
  (see the first two patches)
- Introduce the KVM_ONE_VCPU_TEST_SUITE() macro as suggested
  by Sean (see third patch) and use it in the following patches
- Add a new patch to convert vmx_pmu_caps_test.c, too

Sean Christopherson (1):
  KVM: selftests: Move setting a vCPU's entry point to a dedicated API

Thomas Huth (7):
  KVM: selftests: x86: sync_regs_test: Use vcpu_run() where appropriate
  KVM: selftests: x86: sync_regs_test: Get regs structure before
    modifying it
  KVM: selftests: Add a macro to define a test with one vcpu
  KVM: selftests: x86: Use TAP interface in the sync_regs test
  KVM: selftests: x86: Use TAP interface in the fix_hypercall test
  KVM: selftests: x86: Use TAP interface in the vmx_pmu_caps test
  KVM: selftests: x86: Use TAP interface in the userspace_msr_exit test
