0001-EDAC-Cleanup-atomic_scrub-mess.patch
 This renames an inline function. For the in-kernel code not that much
 of a deal but if there are any external drivers anywhere which rely on
 asm/edac.h this API change may cause trouble.
0002-arm64-Enable-EDAC-on-ARM64.patch
 Looks ok.
0003-MAINTAINERS-Add-entry-for-APM-X-Gene-SoC-EDAC-driver.patch
 Looks safe.
0004-Documentation-Add-documentation-for-the-APM-X-Gene-S.patch
 Looks safe.
0005-EDAC-Add-APM-X-Gene-SoC-EDAC-driver.patch
 Not sure what exactly "dropped suggested merge changes" means but otherwise
 only adding a new driver. Should not cause regressions.
0006-arm64-Add-APM-X-Gene-SoC-EDAC-DTS-entries.patch
 Only device tree change, so at least no effect on other arches.
0007-EDAC-edac_stub-Drop-arch-specific-include.patch
 Dropping an include file. Should be harmless but is it needed?
0008-UBUNTU-Config-Add-XGENE_EDAC-EDAC_SUPPORT-and-EDAC_A.patch
 Looks ok.

So 0001 may pose a risk for breaking API. 0003 and 0004 might not strictly be
required but good to include for completeness and pose no risk. 0007 does not
look strictly required at first glance but maybe there is more to it than is
obvious and it should be safe as long as compile was tested on all supported
arches. The rest looks ok for the purpose of getting a new driver enabled.
