KVM selftests changes for 6.16:

 - Add support for SNP to the various SEV selftests.

 - Add a selftest to verify fastops instructions via forced emulation.

 - Add MGLRU support to the access tracking perf test.

KVM: selftests: Add library support for interacting with SNP

2025-05-02T19:32:33+00:00

Extend the SEV library to include support for SNP ioctl() wrappers,
which aid in launching and interacting with a SEV-SNP guest.

perf cap: Add __NR_capget to arch/x86 unistd

2024-10-28T16:04:52+00:00

As there are duplicated kernel headers in tools/include libc can pick
up the wrong definitions. This was causing the wrong system call for
capget in perf.

To pick the changes in:

  aa8d1f48d353b046 ("KVM: x86/mmu: Introduce a quirk to control memslot zap behavior")

That don't change functionality in tools/perf, as no new ioctl is added
for the 'perf trace' scripts to harvest.
