revert support for arbitrary symbol length in modversion in hwe kernels

[Andrea Righi]

The following patch may break user-space, providing an actual ABI change:

  UBUNTU: SAUCE: modpost: support arbitrary symbol length in modversion

This is not critical for new releases (also considering that the potential breakage is unlikely to happen, unless some tools/scripts/apps are inspecting modules' internals - likely only kmod tools, that are ok with this change), but for LTS releases it is just safer to prevent adding this change.

Keep in mind that this patch is required to enable Rust support in the generic kernel, but it is not required for hwe kernels, because we do not enable Rust support for them.

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 2039010

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 bug is awaiting verification that the linux-gcp-6.5/6.5.0-1010.10~22.04.3 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-linux-gcp-6.5' to 'verification-done-jammy-linux-gcp-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-gcp-6.5' to 'verification-failed-jammy-linux-gcp-6.5'.

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!
