If we're an agent/end-point or fsl_add_bridge doesn't succeed due to some

This serials of patches include two parts.
First, we unify the pci initialization code using platform driver
mechanism. Then, we add PM support for deep sleep stat to save and
restore inbound/outbound window registers.

DO_KVM will need to identify the particular exception type.
There is an existing set of arbitrary numbers that Linux passes,
but it's an undocumented mess that sort of corresponds to server/classic
exception vectors but not really.
FIXME: Replace the existing trap numbering rather than add to it.
The PID handling is e500v1/v2-specific, and is moved to e500.c.
The MMU sregs code and kvmppc_core_vcpu_translate will be shared with
e500mc, and is moved from e500.c to e500_tlb.c.

Move vcpu to the beginning of vcpu_e500 to give it appropriate
prominence, especially if more fields end up getting added to the

Keeping two separate headers for e500-specific things was a
pain, and wasn't even organized along any logical boundary.
There was TLB stuff in despite the existence of
