<title>i7300_edac: Fix device reference count</title>

pci_get_device() decrements the reference count of "from" (last
argument) so when we break off the loop successfully we have only one
device reference - and we don't know which device we have. If we want
a reference to each device, we must take them explicitly and let
the pci_get_device() walk complete to avoid duplicate references.

This is serious, as over-putting device references will cause
the device to eventually disappear. Without this fix, the kernel
crashes after a few insmod/rmmod cycles.

Tested on an Intel S7000FC4UR system with a 7300 chipset.

<content type='text'>
The reference count changes done by pci_get_device can be a little
misleading when the usage diverges from the most common scheme. The
reference count of the device passed as the last parameter is always
decreased, even if the function returns no new device. So if we are
going to try alternative device IDs, we must manually increment the
device reference count before each retry. If we don't, we end up
decreasing the reference count, and after a few modprobe/rmmod cycles
the PCI devices will vanish.

In other words and as Alan put it: without this fix the EDAC code
corrupts the PCI device list.

We're using edac_mc_workq_setup() both on the init path, when
we load an edac driver and when we change the polling period
(edac_mc_reset_delay_period) through /sys/.../edac_mc_poll_msec.

On that second path we don't need to init the workqueue which has been
initialized already.

Thanks to Tejun for workqueue insights.

Sanitize code even more to accept unsigned longs only and to not allow
polling intervals below 1 second as this is unnecessary and doesn't make
much sense anyway for polling errors.

If you do

  echo 0 &gt; /sys/module/edac_core/parameters/edac_mc_poll_msec

the following stack trace is output because the edac module is not
designed to poll with a timeout of zero.

If you do

  echo 0 &gt; /sys/module/edac_core/parameters/edac_mc_poll_msec

the following stack trace is output because the edac module is not
designed to poll with a timeout of zero.

Pull x86 RAS changes from Ingo Molnar:

 - SCI reporting for other error types not only correctable ones

 - GHES cleanups

 - Add the functionality to override error reporting agents as some
   machines are sporting a new extended error logging capability which,
   if done properly in the BIOS, makes a corresponding EDAC module
   redundant

 - PCIe AER tracepoint severity levels fix

 - Error path correction for the mce device init

 - MCE timer fix

 - Add more flexibility to the error injection (EINJ) debugfs interface

* 'x86-ras-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, mce: Fix mce_start_timer semantics
  ACPI, APEI, GHES: Cleanup ghes memory error handling
  ACPI, APEI: Cleanup alignment-aware accesses
  ACPI, APEI, GHES: Do not report only correctable errors with SCI
  ACPI, APEI, EINJ: Changes to the ACPI/APEI/EINJ debugfs interface
  ACPI, eMCA: Combine eMCA/EDAC event reporting priority
  EDAC, sb_edac: Modify H/W event reporting policy
  EDAC: Add an edac_report parameter to EDAC
  PCI, AER: Fix severity usage in aer trace event
  x86, mce: Call put_device on device_register failure
