@ -180,3 +180,12 @@ Why: These events are not correct, and do not properly let userspace know
when a file system has been mounted or unmounted. Userspace should
poll the /proc/mounts file instead to detect this properly.
Who: Greg Kroah-Hartman <gregkh@suse.de>
---------------------------
What: Support for NEC DDB5074 and DDB5476 evaluation boards.
When: June 2006
Why: Board specific code doesn't build anymore since ~2.6.0 and no
users have complained indicating there is no more need for these
boards. This should really be considered a last call.
Who: Ralf Baechle <ralf@linux-mips.org>

EDAC is designed to report errors in the core system.
These are low-level errors that are reported in the CPU or
supporting chipset: memory errors, cache errors, PCI errors,
thermal throttling, etc.. If unsure, select 'Y'.
If this code is reporting problems on your system, please
see the EDAC project web pages for more information at:
<http://bluesmoke.sourceforge.net/>
and:
<http://buttersideup.com/edacwiki>
There is also a mailing list for the EDAC project, which can
be found via the sourceforge page.
