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.

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.

Cosmetic indentation/formatting cleanup for EDAC code. Make sure we
are using tabs rather than spaces to indent, etc.

- 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.

- After we unregister a kobject, wait for our kobject release method
to call complete(). This causes us to wait until the kobject
reference count reaches 0. Otherwise, a task accessing the EDAC
sysfs interface can hold the reference count above 0 until after the
EDAC module has been unloaded. When the reference count finally
drops to 0, this will result in an attempt to call our release
method inside the EDAC module after the module has already been
unloaded.
This isn't the best fix, since a process can get stuck sleeping forever
uninterruptibly if the user does the following:
rmmod my_module < /sys/my_sysfs/file
I'll go back and implement a better fix later. However this should
be ok for now.
- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather
than from edac_mc_free(). Since edac_mc_add_mc() calls
edac_create_sysfs_mci_device(), edac_mc_del_mc() should call
edac_remove_sysfs_mci_device().

Perform the following name substitutions on all source files:

sed 's/bs_thread/edac_thread/g'

The names that start with BS_ or bs_ are artifacts of when the code
was called "bluesmoke".

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.

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.
