[Pull][SRU Zesty][v2] Add support for RAS features on ARM64

Manoj Iyer
The following pull request adds RAS support to ARM64. The patches were tested on QDF2400 and UEFI based AMD64 systems using mce-test testsuite. 

Patches track bugs:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1696852

I had previously submitted similar patches based on linux-next, but these patches here are cherry-picked and backported from the linus's tree. Please review and consider for SRU.

This is (still) a big change across subsystems to add feature support. I saw
Seth picked things up for Artful. So my preference would be to give that at
least some time to settle before moving everything into Zesty, too.

Re: [Pull][SRU Zesty][v2] Add support for RAS features on ARM64

Manoj Iyer
Stefan,

The RAS patch series was submitted previously as SRU to Zesty & to Artful, this patch series was fix-committed to Artful and is currently pending SRU to zesty. Tracked in bugs: 

https://launchpad.net/bugs/1698448

This patch was regression tested on AMD64, Power8 and 4 different ARM64 systems. Details of tests and test kernel can be found in the bug:  https://launchpad.net/bugs/1696570 (and in https://launchpad.net/bugs/1706141). The test kernel based on Ubuntu Zesty tag Ubuntu-4.10.0-29.33 with RAS patches and EDAC_GHES enablement config patch was tested by me as well as Qualcomm for functionality, and test results were posted to the bug report as comments by me and Tyler Baicar.

Also, we have been testing the early incarnation of the RAS patches along with the EDAC_GHES support for quite sometime in the periodic Xenial UOSE builds we did for QDF2400 systems. We therefore have high degree of confidence that the RAS patches and the EDAC_GHES support works as expected on QDF2400 systems, and poses a low degree of regression risk on other architectures.

The RAS patches have had some time to bake in Artful, and we have provided additional testing on QDF2400 and other ARM64 systems, and regression tested on AMD64 and Power8. Please reconsider this patch series for SRU in Zesty.

Thanks
Manoj Iyer

Allright, if all has been tested as stated, lets try and hope for the best.
