Subject: powerpc: EEH failure to mark pci slot as frozen.
From: linas@xxxxxxxxxxxxxx (Linas Vepstas)
Bug fix: when marking a slot as frozen, we forgot to mark pci device itself
as frozen. (we did manage to mark the pci children, but forget the parent
itself.)
This is needed so that some device drivers can check the pci status in
critical sections (e.g. in spin loops with interrupts disabled).
