2c4f4ecb7a [SPARC64]: Add domain-services nodes to VIO device tree.
They sit under the root of the MD tree unlike the rest of
the LDC channel based virtual devices.

cb48123584 [SPARC64]: Assorted LDC bug cures.
1) LDC_MODE_RELIABLE is deprecated an unused by anything, plus
   it and LDC_MODE_STREAM were mis-numbered.

2) read_stream() should try to read as much as possible into
   the per-LDC stream buffer area, so do not trim the read_nonraw()
   length by the caller's size parameter.

3) Send data ACKs when necessary in read_nonraw().

4) In read_nonraw() when we get a pure ACK, advance the RX head
   unconditionally past it.

5) Provide the ACKID field in the ldcdgb() packet dump in read_nonraw().
   This helps debugging stream mode LDC channel problems.

6) Decrease verbosity of rx_data_wait() so that it is more useful.
   A debugging message each loop iteration is too much.

7) In process_data_ack() stop the loop checking when we hit lp->tx_tail
   not lp->tx_head.

8) Set the seqid field properly in send_data_nack().

5a606b72a4 [SPARC64]: Do not ACK an INO if it is disabled or inprogress.
This is also a partial workaround for a bug in the LDOM firmware which
double-transmits RX inos during high load.  Without this, such an
event causes the kernel to loop forever in the interrupt call chain
ACK'ing but never actually running the IRQ handler (and thus clearing
the interrupt condition in the device).

There is still a bad potential effect when double INOs occur,
not covered by this changeset.  Namely, if the INO is already on
the per-cpu INO vector list, we still blindly re-insert it and
thus we can end up losing interrupts already linked in after
it.

We could deal with that by traversing the list before insertion,
but that's too expensive for this edge case.

e53e97ce3c [SPARC64]: Add LDOM virtual channel driver and VIO device layer.
Virtual devices on Sun Logical Domains are built on top
of a virtual channel framework.  This, with help of hypervisor
interfaces, provides a link layer protocol with basic
handshaking over which virtual device clients and servers
communicate.

Built on top of this is a VIO device protocol which has it's
own handshaking and message types.  At this layer attributes
are exchanged (disk size, network device addresses, etc.)
descriptor rings are registered, and data transfers are
triggers and replied to.

905497c4b2 [CPUFREQ] Longhaul - Option to disable ACPI C3 support
On some motherboards ACPI C3 is available, but it isn't
causing frequency transition on VIA Nehemiah. Longhaul
wasn't working at all earlier, but due to
scaling_cur_speed returning true CPU frequency now, it
looks like CPU is getting stuck at highest frequency
since 2.6.21. I didn't find a reason. Halt is causing
frequency transition.

c397368232 Remove old i386 setup code
This removes the old i386 setup code.  This is done as a separate patch
to avoid breaking git bisect as some of the i386 code was also used by
the old x86-64 code.

91a6c462b0 Use the new x86 setup code for x86-64; unify with i386
This unifies arch/*/boot (except arch/*/boot/compressed) between
i386 and x86-64, and uses the new x86 setup code for x86-64 as well.

4fd06960f1 Use the new x86 setup code for i386
This patch hooks the new x86 setup code into the Makefile machinery.  It
also adapts boot/tools/build.c to a two-file (as opposed to three-file)
universe, and simplifies it substantially.

5e8ddcbe86 Video mode probing support for the new x86 setup code
Video mode probing for the new x86 setup code.  This code breaks down
different drivers into modules.  This code deliberately drops support
for a lot of the vendor-specific mode probing present in the assembly
version, since a lot of those probes have been found to be stale in
current versions of those chips -- frequently, support for those modes
have been dropped from recent video BIOSes due to space constraints,
but the video BIOS signatures are still the same.

However, additional drivers should be extremely straightforward to plug
in, if desirable.

31b54f40e1 CPU features verification for the new x86 setup code

By doing this in the setup code we can be guaranteed to still be able to
