The content of this patch series is at:
git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/i7core.git for_linus
The first submission were done on Sept, 5 but weren't reviewed until
yesterday.
It is not yet a pull request. It is just the last version, after the
last review.
My intention is to submit likely tomorrow a git pull request if
everything is ok and hoping that Linus will still accept it for 2.6.32.
This time I'm sending the it as a patch series for better review. The complete
patchset is being sent to EDAC ML ([email protected]).
Only this email and two others of this series is c/c at LKML. If more people is
interested on reviewing it, you can always look at -git and/or bluesmoke archives.
The two patches c/c at LKML are:
- the one that touches at PCI, for probing buses 254 and 255 - since, by
default, ACPI bios doesn't announce those buses with MCU registers;
- edac_mce glue driver, that add two hooks on mce that are called only if a
driver is registered for receiving mce log events. This is needed in order to
get corrected error reports at the EDAC driver.
Cheers,
Mauro

Interesting, but yes, definitely it needs more reviews.

1.6.4.3
As pointed By Arjan, Hidetoshi and Borislav, the edac glue had the
risk of causing dead locks with NMI code. Due to that, I'm submitting
a patch that replaces it to use, instead, a ringbuffer.
I also found a bug at the new edac sysfs methods when more than one memory
controller were used, and added a small patch to improve error injection
address mask.
Please review.
The entire patch series is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/i7core.git for_linus
Cheers,
Maur

Current code only works when there's just one memory
controller, since we need one kobj for each instance.
