[SPARC64]: Fill holes in hypervisor APIs and fix KTSB registry.
Several interfaces were missing and others misnumbered or improperly documented. Also, make sure to check the return value when registering the kernel TSBs with the hypervisor. This helped to find the 4MB kernel TSB alignment bug fixed in a previous changeset. Signed-off-by: David S. Miller <davem@davemloft.net>
