KVM: selftests: Move setting a vCPU's entry point to a dedicated API Extract the code to set a vCPU's entry point out of vm_arch_vcpu_add() and into a new API, vcpu_arch_set_entry_point(). Providing a separate API will allow creating a KVM selftests hardness that can handle tests that use different entry points for sub-tests, whereas *requiring* the entry point to be specified at vCPU creation makes it difficult to create a generic harness, e.g. the boilerplate setup/teardown can't easily create and destroy the VM and vCPUs.

KVM: selftests: Use the right memslot for code, page-tables, and data allocations Now that kvm_vm allows specifying different memslots for code, page tables, and data, use the appropriate memslot when making allocations in common/libraty code. Change them accordingly: - code (allocated by lib/elf) use the CODE memslot - stacks, exception tables, and other core data pages (like the TSS in x86) use the DATA memslot - page tables and the PGD use the PT memslot - test data (anything allocated with vm_vaddr_alloc()) uses the TEST_DATA memslot No functional change intended. All allocators keep using memslot #0.

KVM: selftests: Get rid of kvm_util_internal.h Fold kvm_util_internal.h into kvm_util_base.h, i.e. make all KVM utility stuff "public". Hiding struct implementations from tests has been a massive failure, as it has led to pointless and poorly named wrappers, unnecessarily opaque code, etc... Not to mention that the approach was a complete failure as evidenced by the non-zero number of tests that were including kvm_util_internal.h.

KVM: selftests: Add support for vcpu_args_set to aarch64 and s390x Currently vcpu_args_set is only implemented for x86. This makes writing tests with multiple vCPUs difficult as each guest vCPU must either a.) do the same thing or b.) derive some kind of unique token from it's registers or the architecture. To simplify the process of writing tests with multiple vCPUs for s390 and aarch64, add set args functions for those architectures.
