Christian Krafft 22b6e59047 [POWERPC] cbe_thermal: Fix initialization of sysfs attribute_group
This patch adds NULL to the initialization of the attribute_groups.
The spu_attributes and ppe_attributes arrays are arrays of pointers
that need to be terminated with a NULL entry.

Geoff Levand e28b003136 [POWERPC] cell: abstract spu management routines
This adds a platform specific spu management abstraction and the coresponding
routines to support the IBM Cell Blade.  It also removes the hypervisor only
resources that were included in struct spu.

Three new platform specific routines are introduced, spu_enumerate_spus(),
spu_create_spu() and spu_destroy_spu().  The underlying design uses a new
type, struct spu_management_ops, to hold function pointers that the platform
setup code is expected to initialize to instances appropriate to that platform.

For the IBM Cell Blade support, I put the hypervisor only resources that were
in struct spu into a platform specific data structure struct spu_pdata.

Christian Krafft b3d7dc1967 [POWERPC] cell: add temperature to SPU and CPU sysfs entries
This patch adds a module that registers sysfs attributes to CPU and SPU
containing the temperature of the CBE.

They can be found under
/sys/devices/system/spu/cpuX/thermal/temperature[0|1]
/sys/devices/system/spu/spuX/thermal/temperature

The temperature is read from the on-chip temperature sensors.
