Currently, bsg doesn't make class backlinks (a process whereby you'd get
a link to bsg in the device directory in the same way you get one for
sg). This is because the bsg device is uninitialised, so the class
device has nothing it can attach to. The fix is to make the bsg device
point to the cdevice of the entity creating the bsg, necessitating
changing the bsg_register_queue() prototype into a form that takes the
generic device.

[SPARC]: Make sure dev_archdata is filled in for all devices.
[SPARC]: Define minimal struct dev_archdata, similarly to sparc64.
[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.

These patches add full SSP/MCU support for the HP Jornada 720
machine. Its needed to handle keyboard, touchscreen, battery
and backlight/lcd.
The main driver exports functions and the header file exports
the command values. When talking to the MCU the general procedure
is to start MCU, send command (using ssp_inout(command)), the
proper reply is always TXDUMMY. After receiving TXDUMMY you can
send the value you wish pushed (for example brightness level).
End with ssp_end() so the spinlock gets unlocked.
Drivers using this havent been implemented yet, but will shortly.

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

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

Addition of a spufs-global "cbe_info" array. Each entry contains information
about one Cell/B.E. node, namelly:
* list of spus (both free and busy spus are in this list);
* list of free spus (replacing the static spu_list from spu_base.c)
* number of spus;
* number of reserved (non scheduleable) spus.
SPE affinity implementation actually requires only access to one spu per
BE node (since it implements its own pointer to walk through the other spus
of the ring) and the number of scheduleable spus (n_spus - non_sched_spus)
However having this more general structure can be useful for other
functionalities, concentrating per-cbe statistics / data.

The pmi driver got simplified by removing support for multiple devices.
As there is no more than one pmi device per maschine, there is no need to
specify the device for listening and sending messages.
This way the caller (cbe_cpufreq) doesn't need to scan the device tree.
When registering the handler on a board without a pmi
interface, pmi.c will just return -ENODEV.

broken out of the earlier version of this patch. So this is

2. move the declarations of those suspend functions to pm.h

int save_size;
void (*save)(unsigned long *);
void (*restore)(unsigned long *);
int (*valid)(suspend_state_t state);
void (*enter)(suspend_state_t state);
}
2. processor specific registers saving and restoring are performed
by calling the corresponding (*save) and (*restore)
3. pxa_cpu_pm_fns->save_size should be initialized to the required
size for processor specific registers saving, the allocated
memory address will be passed to (*save) and (*restore)
memory allocation happens early in pxa_pm_init(), and save_size
should be assigned prior to this (which is usually true, since
pxa_pm_init() happens in device_initcall()
4. there're some redundancies for those SLEEP_SAVE_XXX and related
macros, will be fixed later, one way possible is for the system
devices to handle the specific registers saving and restoring
