KVM selftests are failing

[Ahmed Soliman]

Hello,

KVM Self tests located at tools/testing/selftests/kvm seams to be failing.
I have tried:
 - dirty_log_test
 - x86_64/cr4_cpuid_sync_test
 - x86_64/evmcs_test
 - x86_64/platform_info_test
 - x86_64/set_sregs_test
 - x86_64/state_test
 - x86_64/sync_regs_test
 - x86_64/vmx_tsc_adjust_test

All of them triggered the following assert:

        ==== Test Assertion Failure ====
        lib/kvm_util.c:596: ret == 0
        pid=24507 tid=24507 - Invalid argument

        addr: 0x7f3117350000
        length: 0x200000

I have tried the tests on both kvm(next) branch
commit 22a7cdcae6a4a3c89748 as well as
torvald's master  4.20-rc2.
