[SPARC]: Fix serial console device detection.
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.

Revert "sys_time() speedup"
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

[CELL] cell: indexing of SPUs based on firmware vicinity properties
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).

KVM: MMU: Fix oopses with SLUB
The kvm mmu uses page->private on shadow page tables; so does slub, and
an oops result. Fix by allocating regular pages for shadows instead of
using slub.

KVM: Fix memory slot management functions for guest smp
The memory slot management functions were oriented against vcpu 0, where
they should be kvm-wide. This causes hangs starting X on guest smp.
Fix by making the functions (and resultant tail in the mmu) non-vcpu-specific.
Unfortunately this reduces the efficiency of the mmu object cache a bit. We
may have to revisit this later.
