Mike Chan 84db003f24 [PATCH] EDAC: Fix in e752x mc driver
This fix/change returns the offset into the page for the ce/ue error, instead
of just 0.  The e752x dram controller reads 34:6 of the linear address with
the error.

Brian Pomerantz 9962fd017b [PATCH] EDAC: e752x byte access fix
The reading of the DRA registers should be a byte at a time (one register at a
time) instead of 4 bytes at a time (four registers).  Reading a dword at a
time retrieves erroneous information from all but the first register.  A
change was made to read in each register in a loop prior to using the data in
those registers.

Brian Pomerantz dfb2a76378 [PATCH] EDAC: e752x bit mask fix
The fatal vs.  non-fatal mask for the sysbus FERR status is incorrect
according to the E7520 datasheet.  This patch corrects the mask to correctly
handle fatal and non-fatal errors.

Doug Thompson 1318952514 [PATCH] EDAC: probe1 cleanup 1-of-2
- Add lower-level functions that handle various parts of the initialization
  done by the xxx_probe1() functions.  Some of the xxx_probe1() functions are
  much too long and complicated (see "Chapter 5: Functions" in
  Documentation/CodingStyle).

- Cleanup of probe1() functions in EDAC

Doug Thompson 2d7bbb91c8 [PATCH] EDAC: mc numbers refactor 1-of-2
Remove add_mc_to_global_list().  In next patch, this function will be
reimplemented with different semantics.

1 Reimplement add_mc_to_global_list() with semantics that allow the caller to
  determine the ID number for a mem_ctl_info structure.  Then modify
  edac_mc_add_mc() so that the caller specifies the ID number for the new
  mem_ctl_info structure.  Platform-specific code should be able to assign the
  ID numbers in a platform-specific manner.  For instance, on Opteron it makes
  sense to have the ID of the mem_ctl_info structure match the ID of the node
  that the memory controller belongs to.

2 Modify callers of edac_mc_add_mc() so they use the new semantics.

Doug Thompson 37f04581ab [PATCH] EDAC: PCI device to DEVICE cleanup
Change MC drivers from using CVS revision strings for their version number,
Now each driver has its own local string.

Remove some PCI dependencies from the core EDAC module.  Made the code 'struct
device' centric instead of 'struct pci_dev' Most of the code changes here are
from a patch by Dave Jiang.  It may be best to eventually move the
PCI-specific code into a separate source file.

mark gross 96941026a5 [PATCH] EDAC Coexistence with BIOS
Address the issue of EDAC/BIOS coexistence for the e752x chip-sets.

We have found a problem where the BIOS will start the system with the error
registers (dev0:fun1) hidden and assuming it has exclusive access to them.
The edac driver violates this assumption.

The workaround this patch offers is to honor the hidden-ness as an
indication that it is not safe to use those registers.

Dave Peterson 18dbc337af [PATCH] EDAC: protect memory controller list
- Fix code so we always hold mem_ctls_mutex while we are stepping
  through the list of mem_ctl_info structures.  Otherwise bad things
  may happen if one task is stepping through the list while another
  task is modifying it.  We may eventually want to use reference
  counting to manage the mem_ctl_info structures.  In the meantime we
  may as well fix this bug.

- Don't disable interrupts while we are walking the list of
  mem_ctl_info structures in check_mc_devices().  This is unnecessary.

Alan Cox da9bb1d27b [PATCH] EDAC: core EDAC support code
This is a subset of the bluesmoke project core code, stripped of the NMI work
which isn't ready to merge and some of the "interesting" proc functionality
that needs reworking or just has no place in kernel.  It requires no core
kernel changes except the added scrub functions already posted.

The goal is to merge further functionality only after the core code is
accepted and proven in the base kernel, and only at the point the upstream
extras are really ready to merge.

From: doug thompson <norsk5@xmission.com>

  This converts EDAC to sysfs and is the final chunk neccessary before EDAC
  has a stable user space API and can be considered for submission into the
  base kernel.
