[patch 0/5] (hopefully) final 2.6.23 fixes for cell platform

[patch 0/5] (hopefully) final 2.6.23 fixes for cell platform

[Arnd Bergmann]

Hi Paul,

A few bugs came up on the cell platform when testing on the lastest
prototype version of a future hardware. The first three patches are
all meant to track changes required for the fixes that have gone
into the firmware. Patch 4 is for a bug that showed up during testing,
and the final patch is the defconfig update that you probably want
to do for the other platforms as well.

Please forward for inclusion in 2.6.23!

	Arnd <><

[patch 1/5] spu_manage: use newer physical-id attribute

[Arnd Bergmann]

[-- Attachment #1: 36162.diff --]
[-- Type: text/plain, Size: 2119 bytes --]

From: Christian Krafft <krafft@de.ibm.com>
Legacy device tree used the reg property for the physical id of an spe.
On newer device tree layouts the reg property contains the "correct" value
in the reg attribute. So there has been intoduced the "physical-id" on newer
devicetree layouts. The id is stored by spu_manage into the spu struct as spe_id.
cbe_thermal has been changed to use the spu->spe_id.
There's no need for the thermal code has to check devicetree attributes for itself.

[patch 2/5] cell: support pinhole-reset on IBM cell blades

[Arnd Bergmann]

[-- Attachment #1: 34342.diff --]
[-- Type: text/plain, Size: 3465 bytes --]

From: Arnd Bergmann <arnd.bergmann@de.ibm.com>
The Cell Broadband Engine has a method of injecting a
system-reset-exception from an external source into the
operating system, which should trigger the regular behaviour
of entering xmon or kdump.

Unfortunately, the exception handler cannot distinguish it from
other interrupt causes by the SRR1 register, which gets used
for this on Power 6 and others.

IBM Blade servers that want to support triggering the
system reset exception using a pinhole button in the front
panel therefore use an extra register to determine the
reset cause.

[patch 3/5] Axonram module modification for latest firmware API changes

[Arnd Bergmann]

[-- Attachment #1: 35766.diff --]
[-- Type: text/plain, Size: 3576 bytes --]

From: Maxim Shchetynin <maxim@de.ibm.com>

Firmware would not deliver two interrupt numbers in device-tree any more
but only one, for correctable ECC, because uncorrectable ECC from now
handles firmware itself.
Changes in the axonram module are necessary because in the old version, if
it is not allowed to fetch the second interrupt number from device-tree,
it interpretes this as an error case and exits.
