KVM: selftests: Rename the ASSERT_EQ macro There is already an ASSERT_EQ macro in the file tools/testing/selftests/kselftest_harness.h, so currently KVM selftests can't include test_util.h from the KVM selftests together with that file. Rename the macro in the KVM selftests to TEST_ASSERT_EQ to avoid the problem - it is also more similar to the other macros in test_util.h that way.

KVM: selftests: Add test for race in kvm_recalculate_apic_map() Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during APIC map construction to hunt for TOCTOU bugs in KVM. KVM's optimized map recalc makes multiple passes over the list of vCPUs, and the calculations ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where toggling LAPIC_MODE_DISABLED is quite interesting.
