x86, amd_nb: Export model 0x10 and later PCI id

Add the F3 PCI id of F15h, model 0x10 to pci_ids.h and to the amd_nb
code which generates the list of northbridges on an AMD box. Shorten
define name while at it so that it fits into pci_ids.h.

x86, MCE, AMD: Remove shared banks sysfs linking

The code used to create a symlink on all non-BSP cores of a node when
the MCi_MISCj bank is present once per node. (This is generally the
case with bank 4 on AMD). However, these sysfs links cause a bunch
of problems with cpu off-/onlining testing and are, as such, a bit
overengineered. IOW, there's nothing wrong with having normal sysfs
files for the shared banks since the corresponding MSRs are replicated
across each core anyway.

x86, MCE, AMD: Move shared bank to node descriptor

Well, instead of having a real bank 4 on the BSP of each node and
symlinks on the remaining cores, we push it up into the amd_northbridge
descriptor which now contains a pointer to the northbridge bank 4
because the bank is one per northbridge and, as such, belongs in the NB
descriptor anyway.

Each time we hotplug CPUs, we use the northbridge pointer to copy the
shared bank into the per-CPU array of threshold_banks pointers, or
destroy it when the last CPU on the node goes offline, or create it when
the first comes online.

x86, MCE, AMD: Print decimal thresholding values

If one sets the threshold limit, say to 25:

$ echo 25 > machinecheck0/threshold_bank4/misc0/threshold_limit

and then reads it back again, it gives

$ cat machinecheck0/threshold_bank4/misc0/threshold_limit
19

which is actually 0x19 but we don't know that.

Make all output decimal.

x86, MCE, AMD: Make error_count read only

Until now, writing to error count caused the code to reset the
thresholding bank to the current thresholding limit and start counting
errors from the beginning.

This is misleading and unclear, and can be accomplished by writing the
old thresholding limit into ->threshold_limit.

Make error_count read-only with the functionality to show the current
error count.

Merge tag 'amd-thresholding-fixes-for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/ras/ras into x86/mce

Pull in AMD MCE thresholding fixes for v3.6, from Borislav Petkov:

" Those are a bunch of patches which give the MCE thresholding code a
  hard look and a scrubbing to remove a couple of annoyances like sysfs
  warnings when running CPU off-/online tests and the threshold_bank4 node
  under /sys/devices/system/machinecheck/ is a symlink.

  It also gives proper names to the thresholding banks instead of simply
  enumerating them, like this:

ACPI / PM: Drop pm_message_t argument from device suspend callback

None of the drivers implementing the ACPI device suspend callback
uses the pm_message_t argument of it, so this argument may be dropped
entirely from that callback.  This will simplify switching the ACPI
bus type to PM handling based on struct dev_pm_ops.

ACPI / PM: Make acpi_bus_type use driver struct dev_pm_ops callbacks

Modify acpi_bus_type so that it executes PM callbacks provided
by drivers through their struct dev_pm_ops objects, if present,
while still allowing the legacy ACPI PM callbacks to take precedence.
This will make it possible to convert ACPI drivers one by one to
handling PM through struct dev_pm_ops instead of the legacy way.

The code added by this change is temporary and will be removed
when all of the drivers in question have been switched over to
the PM handling based on struct dev_pm_ops.
