[PATCH] x86-64: 64bit PIC SMP trampoline
This modifies the SMP trampoline and all of the associated code so
it can jump to a 64bit kernel loaded at an arbitrary address.
The dependencies on having an idenetity mapped page in the kernel
page tables for SMP bootup have all been removed.
In addition the trampoline has been modified to verify
that long mode is supported. Asking if long mode is implemented is
down right silly but we have traditionally had some of these checks,
and they can't hurt anything. So when the totally ludicrous happens
we just might handle it correctly.
