This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.
The format:
1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
underscores.

64-bit hypercall interface can pass a maddr in one argument rather
than splitting it.

Use callback_op hypercall to register callbacks in a 32/64-bit
independent way (64-bit doesn't need a code segment, but that detail
is hidden in XEN_CALLBACK).

The 64-bit calling convention for hypercalls uses different registers
from 32-bit. Annoyingly, gcc's asm syntax doesn't have a way to
specify one of the extra numeric reigisters in a constraint, so we
must use explicitly placed register variables. Given that we have to
do it for some args, may as well do it for all.
Also fix syntax gcc generates for the call instruction itself. We
need a plain direct call, but the asm expansion which works on 32-bit
generates a rip-relative addressing mode in 64-bit, which is treated
as an indirect call. The alternative is to pass the hypercall page
offset into the asm, and have it add it to the hypercall page start
address to generate the call.

64-bit guests can pass 64-bit quantities in a single argument,
so fix up the hypercalls.

Use the new sched_op hypercall, mainly because xenner doesn't support
the old one.

Xen will trap and emulate clts, but its better to use a hypercall.
Also, xenner doesn't handle clts.
