4d9bba9007 KVM: selftests: Use kernel's list instead of homebrewed replacement
Replace the KVM selftests' homebrewed linked lists for vCPUs and memory
regions with the kernel's 'struct list_head'.

425936246f KVM: selftests: Share common API documentation
Move function documentation comment blocks to the header files in
order to avoid duplicating them for each architecture. While at
it clean up and fix up the comment blocks.

9bbf24744e 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.

f90f57b397 KVM: selftests: Implement ucall() for s390x
On s390x, we can neither exit via PIO nor MMIO, but have to use an
instruction like DIAGNOSE. Now that ucall() is implemented, we can
use it in the sync_reg_test on s390x, too.
