Linas Vepstas 054d8ff377 [PATCH] powerpc/pseries: avoid crash in PCI code if mem system not up 
The powerpc code is currently performing PCI setup before memory
initialization.  PCI setup touches PCI config space registers.  If the PCI
card is bad, this will evoke an error, which currrently can't be handled,
as the PCI error recovery code expects kmalloc() to be functional.  This
patch will cause the system to punt instead of crashing with

cpu 0x0: Vector: 300 (Data Access) at [c0000000004434d0]
    pc: c0000000000c06b4: .kmem_cache_alloc+0x8c/0xf4
    lr: c00000000004ad6c: .eeh_send_failure_event+0x48/0xfc

This patch will also print name of the offending pci device.
