034e0ab54b [POWERPC] PS3: Make bus_id and dev_id u64
Change the PS3 bus_id and dev_id from type unsigned int to u64.  These
IDs are 64-bit in the repository, and the special storage notification
device has a device ID of ULONG_MAX.

7eff2e7a8b Driver core: change add_uevent_var to use a struct
This changes the uevent buffer functions to use a struct instead of a
long list of parameters. It does no longer require the caller to do the
proper buffer termination and size accounting, which is currently wrong
in some places. It fixes a known bug where parts of the uevent
environment are overwritten because of wrong index calculations.

Many thanks to Mathieu Desnoyers for finding bugs and improving the
error handling.

6758555da6 [POWERPC] PS3: System-bus modinfo attribute
Add modinfo attribute to ps3_system_bus devices.  Also make them all
children of the same ps3_system_bus 'device' so they appear in a
corresponding subdirectory under /sys/devices.

688b3378da [POWERPC] PS3: System-bus uevent
To allow userspace to automatically load modules, we need to hook up
uevent for ps3_system_bus devices.  I've used the form 'ps3:%d' with
the ps3_match_id, since that's what we use for matching drivers.

6bb5cf1025 [POWERPC] PS3: System-bus rework
Rework the PS3 system bus to unify device support.
 - DMA region sizes must be a power of two
 - storage bus DMA updates:
  - Small fixes for the PS3 DMA core:
      o fix alignment bug
      o kill superfluous test
      o indentation
      o spelling
      o export ps3_dma_region_{create,free}()
  - ps3_dma_region_init():
      o Add `addr' and `len' parameters, so you can create a DMA region that
        does not cover all memory (use `NULL' and `0' to cover all memory).
	This is needed because there are not sufficient IOMMU resources to have
	all DMA regions cover all memory.
      o Uninline
  - Added remove and shutdown routines to all drivers.
  - Added loadable module support to all drivers.
  - Added HV calls for iopte management (needed by sound driver).

ef596c697a [POWERPC] ps3: always make sure were running on a PS3
Add missing checks to PS3 specific drivers ps3av and sys-manager to verify that
we are actually running on a PS3 (pointed out by Arnd).

Correct existing checks in other subsystems/drivers to return -ENODEV instead
of zero.
