Bug Description

SRU Justification

[Impact]

MSFT has requested the inclusion of commit e8dfdf3162eb549d064b8c10b1564f7e8ee82591 ('arm64: efi: Recover from synchronous exceptions occurring in firmware'). It looks generic enough to apply to the master kernel.

Unlike x86, which has machinery to deal with page faults that occur during the execution of EFI runtime services, arm64 has nothing like that, and a synchronous exception raised by firmware code brings down the whole system.

[Test Plan]

This looks like a hard one to reproduce. Boot and regression testing should be sufficient.

[Regression Potential]

Firmware exceptions could still take down the system.

[Other Info]

SF: #00362062

This bug is awaiting verification that the linux/5.15.0-77.84 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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.
