        src/sys/arch/xen/xen: privcmd.c

Log Message:
In Xen 3.2 (c/s 15985) the semantic of the HVM domain builder changed:

hvm: Avoid need for ugly setcpucontext() in HVM domain builder by
pre-setting the vcpu0 to runnable inside Xen, and have the builder
insert a JMP instruction to reach the hvmloader entry point from
address 0x0.

So we have to treat guest physical address 0x0 like every one
or we end in a page fault loop when launching a HVM guest, otherwise.

XXX Keep this for Xen2 as this change hasn't been tested there.
