      x86, apic: Enable lapic nmi watchdog on AMD Family 11h · 7d1849af
      由 Mikael Pettersson 提交于 
      The x86 lapic nmi watchdog does not recognize AMD Family 11h,
resulting in:

  NMI watchdog: CPU not supported

As far as I can see from available documentation (the BKDM),
family 11h looks identical to family 10h as far as the PMU
is concerned.

Extending the check to accept family 11h results in:

  Testing NMI watchdog ... OK.

I've been running with this change on a Turion X2 Ultra ZM-82
laptop for a couple of weeks now without problems.

      x86, Calgary IOMMU quirk: Find nearest matching Calgary while walking up the PCI tree · 4528752f
      由 Darrick J. Wong 提交于 
      On a multi-node x3950M2 system, there's a slight oddity in the
PCI device tree for all secondary nodes:

 30:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1)
  \-33:00.0 PCI bridge: IBM CalIOC2 PCI-E Root Port (rev 01)
     \-34:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)

...as compared to the primary node:

 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1)
  \-01:00.0 VGA compatible controller: ATI Technologies Inc ES1000 (rev 02)
 03:00.0 PCI bridge: IBM CalIOC2 PCI-E Root Port (rev 01)
  \-04:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 1078 (rev 04)

In both nodes, the LSI RAID controller hangs off a CalIOC2
device, but on the secondary nodes, the BIOS hides the VGA
device and substitutes the device tree ending with the disk
controller.

It would seem that Calgary devices don't necessarily appear at
the top of the PCI tree, which means that the current code to
find the Calgary IOMMU that goes with a particular device is
buggy.

Rather than walk all the way to the top of the PCI
device tree and try to match bus number with Calgary descriptor,
the code needs to examine each parent of the particular device;
if it encounters a Calgary with a matching bus number, simply
use that.

Otherwise, we BUG() when the bus number of the Calgary doesn't
match the bus number of whatever's at the top of the device tree.

Extra note: This patch appears to work correctly for the x3950
that came before the x3950 M2.
