are some places where for each hypercall a table element is created.
Instead of manually add each hypercall element to these tables use
an auto generated header built during the make process of the kernel.

Instead of manually list all hypervisor calls in arch/x86/xen/trace.c
use the auto generated list.

The header include/xen/interface/xen.h doesn't contain all definitions
from Xen's version of that header. Update it accordingly.

xen: add xen_pin_vcpu() to support calling functions on a dedicate
Add generic virtualization support for pinning the current vcpu to a
specified physical cpu. As this operation isn't performance critical
(a very limited set of operations like BIOS calls and SMIs is expected
to need this) just add a hypervisor specific indirection.

Use the smp_call_on_cpu() function to call system management
mode on cpu 0.
Make call secure by adding get_online_cpus() to avoid e.g. suspend
resume cycles in between.
