The channel DIMM label does not seem to be used much in the edac code.
However, where it is used (in the core code), it is assumed to not have a
newline embedded.  This leaves the sysfs file newline free which looks
funny when cat'ing it.  Here we just add the trailing newline to the sysfs
chX_dimm_label output...

[Doug Thompson note: the DIMM label is one of the primary uses of EDAC.
User space daemon scripts, edac-utils@sourceforge, populate the DIMM label
fields, via /sys/devices/system/edac attributes, with the silk screen
labels of the motherboard in use.  dmidecode access BIOS tables, but BIOS
tables are well known to be incorrect and useless in these respects.
edac-utils will strip off any newlines before its use of the output, when
displaying DIMM slot silk screen labels.

When updating the edac_mc_poll_msec module parameter from the sysfs

the workq timers.  So that, if we move from a big poll time to a small
one, the small one won't take effect until the big one has timed out.

Here we provide a new module parameter set method to call out to the
update routine.  This brings the /sys/module/edac_core/parameters
functionality up to that provided by the /sys/drivers/system/edac/mc sysfs
module parameter files so that we can remove them or at least link to the

Some code cleanliness issues found by Andrew Morton (thanks!) which should

maintainable.

In particular, we now:

* convert all #define's w/ a parameter to static inlines
* use 1UL rather than 1ULL when calculating an unsigned long
* use pci_disable_device

Preliminary support for the Intel 5100 MCH.  CE and UE errors are reported
along with the current DIMM label information and other memory parameters.

Reasons why this is preliminary:

1) This chip has 2 independent memory controllers which, for best
   perforance, use interleaved accesses to the DDR2 memory.  This
   architecture does not map very well to the current edac data structures
   which depend on symmetric channel access to the interleaved data.
   Without core changes, the best I could do for now is to map both memory
   controllers to different csrows (first all ranks of controller 0, then
   all ranks of controller 1).  Someone much more familiar with the edac
   core than I will probably need to come up with a more general data
   structure to handle the interleaving and de-interleaving of the two
   memory controllers.

2) I have not yet tackled the de-interleaving of the rank/controller
   address space into the physical address space of the CPU.  There is
   nothing fundamentally missing, it is just ending up to be a lot of
   code, and I'd rather keep it separate for now, esp since it doesn't
   work yet...

3) The code depends on a particular i5100 chip select to DIMM mainboard
   chip select mapping.  This mapping seems obvious to me in order to
   support dual and single ranked memory, but it is not unique and DIMM
   labels could be wrong on other mainboards.  There is no way to query
   this mapping that I know of.

4) The code requires that the i5100 is in 32GB mode.  Only 4 ranks per
   controller, 2 ranks per DIMM are supported.  I do not have hardware
   (nor do I expect to have hardware anytime soon) for the 48GB (6 ranks
   per controller) mode.

5) The serial presence detect code should be broken out into a "real"
   i2c driver so that decode-dimms.pl can work.

Implement looking up an inode by node ID after it has been evicted from

(for all file types, not just directories).

The filesystem can set the FUSE_EXPORT_SUPPORT flag in the INIT reply, to
indicate that it supports these special lookups.

Implement export_operations, to allow fuse filesystems to be exported to
NFS.  This feature has been in the out-of-tree fuse module, and is widely
used and tested.

It has not been originally merged into mainline, because doing the NFS
export in userspace was thought to be a cleaner and more efficient way of
doing it, than through the kernel.

While that is true, it would also have involved a lot of duplicated effort
at reimplementing NFS exporting (all the different versions of the
protocol).  This effort was unfortunately not undertaken by anyone, so we
are left with doing it the easy but less efficient way.

If this feature goes in, the out-of-tree fuse module can go away,
which would have several advantages:

  - not having to maintain two versions
  - less confusion for users
  - no bugs due to kernel API changes

Comment from hch:
 - Use the same fh_type values as XFS, since we use the same fh encoding.
