Former is safer (in case TIF_IO_BITMAP is out-of-sync with actual
existence of an I/O bitmap for this process) and more readable, and
probably results in faster code too.

This adds (or moves to the proper place) annotations paralleling those
added in native code in 2.6.18. To make this look less ugly, it
required moving around a few things.

The differences of arch/x86_64/kernel/x8664_ksyms-xen.c over its
native original are benign - the Xen special can therefore be
removed.

The sole (x86-64 specific) difference of
arch/i386/kernel/alternative-xen.c
over its native original can be eliminated by slightly adjusting
x86-64's make_readonly(), and the Xen special can then be removed.

arch/i386/kernel/cpu/intel_cacheinfo-xen.c is identical to
arch/i386/kernel/cpu/intel_cacheinfo.c, hence the Xen special can be
removed.

This patch implements TPM frontend driver resume after checkpointing a
domain. I also now let the front-end wait for the response from the
TPM until the response is there. A response must come due to the
strict request/response nature of the protocol, but the time until the
responses arrives depends on the type of operation that is executed by
the vTPM. Resending a request is not possible with this type of device.

This changes netback to use struct page's mapping field instead of the
index one, and the PageForeign logic the other way around. That way,
CONFIG_SPLIT_PTLOCK_CPUS doesn't have to be suppressed anymore for x86.

Ensure the backend terminates when the frontend vanishes before the
connection is established. This happens when the guest doesn't have
the devices.

While object files generated from C sources should generally not
depend on asm-offsets.h, those generated from assembly sources
should.

This capability means that save/restore will remember contexts of all
online VCPUs at the time of final guest suspend. Any initialised but
offline VCPUs will not be saved!

If xc_map_foreign_range fails, the new domain object is freed,
but it is not removed from the connection list.

Each serial, parallel and monitor device in qemu that is connected to
a pty creates a xenstore node of the form:
<domain-path>/monitor/tty
<domain-path>/serial/<n>/tty
<domain-path>/parallel/<n>/tty
In addition, serial/0 (com1) also registers its information at:
<domain-path>/console/tty
Also fix a realloc() failure memory leak.

XendError). Also remove redundance exception code that is handled by
domain_lookup.

grant table entries instead of the shared ones. I had to move some
functions from grant_table.c into grant_table.h to make them usable by
the ACM module.
