[PATCH 0/4] powerpc/eeh: More precisely error injection

[Gavin Shan <gwshan@linux.vnet.ibm.com>]

Previously, we inject PCI errors through various debugfs entries in
/sys/kernel/debug/powerpc/PCIxxxx/. Unfortunately, the PCI errors
are injected with PHB granularity. It's hard to injection errors to
specified PE. The series of patches adds one more debugfs entry, which
allows to inject errors to specified PE for testing purpose.

echo "pe_no:0:function:0:0" > /sys/kernel/debug/powerpc/PCIxxxx/err_injct

The frequently used "function" would be:
    0 : MMIO read
    4 : CFG read
    6 : MMIO write
    10: CFG write
