[PATCH v1 0/3] Support PCI Error Injection

[Gavin Shan]

The series of patches supports PCI error injection as defined in PAPR spec.
There are 3 RTAS calls related to it:

"ibm,open-errinjct": Apply for token to do error injection
"ibm,close-errinjct": Free the token assigned previously
"ibm,errinjct": Do error injection

For PCI errors, we need manupulate 3 hardware registers by predetermined
OPAL API. In order to export the capability to userland, one OPAL firmware
related sysfs entries are created: /sys/firmware/opal/errinjct. It accepts
strings to call OPAL API to inject specific errors. So it corresponds to
"ibm,errinjct". So "ibm,open-errinjct" and "ibm,close-errinjct" won't be
handled by host kernel and applications have full freedom to implement logic
of themselves for them.
