Merge git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-edac
Pull EDAC patches from Mauro Carvalho Chehab:
- the second part of the EDAC rework:
- Add the sysfs nodes that exports the real memory layout, instead
of the fake one (needed to properly represent Intel memory
controllers since 2002)
- convert EDAC MC to use "struct device" instead of creating the
sysfs nodes via the kobj API
- adds a tracepoint to represent memory errors
- some cleanup patches
- some fixes at i5000, i5400 and EDAC core
- a new EDAC driver for Caldera.
