The patch supports RTAS calls "ibm,{open,close}-errinjct" to
manupliate the token, which is passed to RTAS call "ibm,errinjct"
to indicate the valid context for error injection. Each VM is
permitted to have only one token at once and we simply have one
random number for that.
njection. Finally, to return
the open-token by calling "ibm,close-errinject".
"ibm,errinjct" can be used to inject various errors, not limited to EEH errors.
However, this patchset is going to support injecting EEH errors only for VFIO
PCI devices.
