[PATCH] powerpc/pseries: clear PCI failure counter if no new failures
The current PCI error recovery system keeps track of the number of PCI card
resets, and refuses to bring a card back up if this number is too large.
The goal of doing this was to avoid an infinite loop of resets if a card is
obviously dead. However, if the failures are rare, but the machine has a
high uptime, this mechanism might still be triggered; this is too harsh.
This patch will avoids this problem by decrementing the fail count after an
hour. Thus, as long as a pci card BSOD's less than 6 times an hour, it
will continue to be reset indefinitely. If it's failure rate is greater
than that, it will be taken off-line permanently.
This patch is larger than it might otherwise be because it changes
indentation by removing a pointless while-loop. The while loop is not
needed, as the handler is invoked once fo each event (by schedule_work());
the loop is leftover cruft from an earlier implementation.
