Could SPR 536 be specific to a particular SOC, or maybe it's just a typo in
the code somewhere?

Thank you for the inputs.
The kernel was configured for 'altivec' support and I guess that was
causing the invalid SPR issue.
On reconfiguring the kernel for ppc e500 it did not give ' invalid SPR'
error but gave a blank QEMU console and failed to load the kernel and root
file system.

Using qemu version 2.1.0

Please suggest in case of any missing configurations.
