BugLink: https://bugs.launchpad.net/bugs/1949770
SRU Justification
[Impact]
Microsoft has asked to enable arm64 in Azure 5.11 and subsequent kernels.
This is a preview which will be used to test arm64 as well as ensure
that nothing has been broken in x64 land.
[Test Case]
Microsoft tested.
[Where things could go wrong]
Some of the patches touch common PCI code. Device detection could be impacted.
