Enable arm64 for Hyper-V guests

[Tim Gardner]

SRU Justification

[Impact]

Since linux-azure can also be used for local Hyper-V guests on Windows 10 Pro running on arm64 platforms, enable arm64 build for this kernel as well.

[Test Case]

Boot an arm64 VM on a machine running Win10Pro with Hyper-V.

[Where things could go wrong]

Some of the patches touch common PCI code. Device detection could be impacted.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1949770

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug is awaiting verification that the linux-azure/5.11.0-1023.24 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-hirsute' to 'verification-done-hirsute'. If the problem still exists, change the tag 'verification-needed-hirsute' to 'verification-failed-hirsute'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

All autopkgtests for the newly accepted linux-meta-azure (5.11.0.1023.24) for hirsute have finished running.
The following regressions have been reported in tests triggered by the package:

dahdi-linux/1:2.11.1~dfsg-1ubuntu8 (amd64)

Please visit the excuses page listed below and investigate the failures, proceeding afterwards as per the StableReleaseUpdates policy regarding autopkgtest regressions [1].
