Because xmon_write doesn't change the buffer, we should add 'const'

The best scheme to get uniqueness seems to be:
FOO -- If node lacks "id" property
FOO-$(ID) -- If node has "id" but parent lacks "cfg-handle"
FOO-$(ID)-$(CFG_HANDLE) -- If node has both

The current scheme works on static interpretation of text names, which
is wrong.
The output-device setting, for example, must be resolved via an alias
or similar to a full path name to the console device.
Paths also contain an optional set of 'options', which starts with a
colon at the end of the path. The option area is used to specify
which of two serial ports ('a' or 'b') the path refers to when a
device node drives multiple ports. 'a' is assumed if the option
specification is missing.
This was caught by the UltraSPARC-T1 simulator. The 'output-device'
property was set to 'ttya' and we didn't pick upon the fact that this
is an OBP alias set to '/virtual-devices/console'. Instead we saw it
as the first serial console device, instead of the hypervisor console.
The infrastructure is now there to take advantage of this to resolve
the console correctly even in multi-head situations in fbcon too.
Thanks to Greg Onufer for the bug report.

We ignore all the generated files called "vmlinux*" from the top-level
gitignore, but that also ends up catching a few files that we track, and
that people do edit. Notably the "vmlinux.lds.S" file, that each
architecture has.
You can always use "git add -f" to override the ignore file, but we
might as well just make it explicit for this file.

The VBI DMA is handled in a special way and is marked with a bit.
However, that bit was set at the wrong time and could be cleared
by mistake if a PCM (or other) DMA request would arrive before the
VBI DMA was completed. So on completion of the VBI DMA the driver
no longer knew that that DMA transfer was for VBI data. And this
in turn caused havoc with the card's DMA engine.

This basically reverts commit 4e44f3497d41db4c3b9051c61410dee8ae4fb49c,
while waiting for it to be re-done more completely. There are cases of
people mixing "time()" with higher-resolution time sources, and we need
to take the nanosecond offsets into account.
Ingo has a patch that does that, but it's still under some discussion.
In the meantime, just revert back to the old simple situation of just
doing the whole exact timesource calculations.
But rather than using do_gettimeofday(), use the internal nanosecond
resolution getnstimeofday(), which at least avoids one unnecessary
conversion (since we really don't care about whether the fractional
seconds are nanoseconds or microseconds - we'll just throw them away).

This sorts out the various lists and related locks in the spu code.
In detail:
- the per-node free_spus and active_list are gone. Instead struct spu
gained an alloc_state member telling whether the spu is free or not
- the per-node spus array is now locked by a per-node mutex, which
takes over from the global spu_lock and the per-node active_mutex
- the spu_alloc* and spu_free function are gone as the state change is
now done inline in the spufs code. This allows some more sharing of
code for the affinity vs normal case and more efficient locking
- some little refactoring in the affinity code for this locking scheme

From: Maynard Johnson <mpjohn@us.ibm.com>
This patch updates the existing arch/powerpc/oprofile/op_model_cell.c
to add in the SPU profiling capabilities. In addition, a 'cell' subdirectory
was added to arch/powerpc/oprofile to hold Cell-specific SPU profiling code.
Exports spu_set_profile_private_kref and spu_get_profile_private_kref which
are used by OProfile to store private profile information in spufs data
structures.
Also incorporated several fixes from other patches (rrn). Check pointer
returned from kzalloc. Eliminated unnecessary cast. Better error
handling and cleanup in the related area. 64-bit unsigned long parameter
was being demoted to 32-bit unsigned int and eventually promoted back to
unsigned long.

This patch links spus according to their physical position using
information provided by the firmware through a special vicinity
device-tree property. This property is present in current version
of Malta firmware.
Example of vicinity properties for a node in Malta:
Node: Vicinity property contains phandles of:
spe@0 [ spe@100000 , mic-tm@50a000 ]
spe@100000 [ spe@0 , spe@200000 ]
spe@200000 [ spe@100000 , spe@300000 ]
spe@300000 [ spe@200000 , bif0@512000 ]
spe@80000 [ spe@180000 , mic-tm@50a000 ]
spe@180000 [ spe@80000 , spe@280000 ]
spe@280000 [ spe@180000 , spe@380000 ]
spe@380000 [ spe@280000 , bif0@512000 ]
Only spe@* have a vicinity property (e.g., bif0@512000 and
mic-tm@50a000 do not have it).

This patch provides the spu affinity placement logic for the spufs scheduler.
Each time a gang is going to be scheduled, the placement of a reference
context is defined. The placement of all other contexts with affinity from
the gang is defined based on this reference context location and on a
