KVM: selftests: Add aarch64 get-reg-list test Check for KVM_GET_REG_LIST regressions. The blessed list was created by running on v4.15 with the --core-reg-fixup option.

KVM: selftests: Introduce steal-time test The steal-time test confirms what is reported to the guest as stolen time is consistent with the run_delay reported for the VCPU thread on the host. Both x86_64 and AArch64 have the concept of steal/stolen time so this test is introduced for both architectures. While adding the test we ensure .gitignore has all tests listed (it was missing s390x/resets) and that the Makefile has all tests listed in alphabetical order (not really necessary, but it almost was already...). We also extend the common API with a new num-guest- pages call and a new timespec call. Signed-off-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

selftests: kvm: Test MSR exiting to userspace Add a selftest to test that when the ioctl KVM_X86_SET_MSR_FILTER is called with an MSR list, those MSRs exit to userspace. This test uses 3 MSRs to test this: 1. MSR_IA32_XSS, an MSR the kernel knows about. 2. MSR_IA32_FLUSH_CMD, an MSR the kernel does not know about. 3. MSR_NON_EXISTENT, an MSR invented in this test for the purposes of passing a fake MSR from the guest to userspace. KVM just acts as a pass through. Userspace is also able to inject a #GP. This is demonstrated when MSR_IA32_XSS and MSR_IA32_FLUSH_CMD are misused in the test. When this happens a #GP is initiated in userspace to be thrown in the guest which is handled gracefully by the exception handling framework introduced earlier in this series. Tests for the generic instruction emulator were also added. For this to work the module parameter kvm.force_emulation_prefix=1 has to be enabled. If it isn't enabled the tests will be skipped. A test was also added to ensure the MSR permission bitmap is being set correctly by executing reads and writes of MSR_FS_BASE and MSR_GS_BASE in the guest while alternating which MSR userspace should intercept. If the permission bitmap is being set correctly only one of the MSRs should be coming through at a time, and the guest should be able to read and write the other one directly.

KVM: selftests: test behavior of unmapped L2 APIC-access address Add a regression test for commit 671ddc700fd0 ("KVM: nVMX: Don't leak L1 MMIO regions to L2"). First, check to see that an L2 guest can be launched with a valid APIC-access address that is backed by a page of L1 physical memory. Next, set the APIC-access address to a (valid) L1 physical address that is not backed by memory. KVM can't handle this situation, so resuming L2 should result in a KVM exit for internal error (emulation).
