Bug Description
[Impact]
The 3rd party nvidia driver fails to load on arm64 systems.
[Test Case]
sudo modprobe nvidia
On failure:
[ 812.512205] nvidia: loading out-of-tree module taints kernel.
[ 812.512216] nvidia: module license 'NVIDIA' taints kernel.
[ 812.512218] Disabling lock debugging due to kernel taint
[ 812.711108] nvidia: module verification failed: signature and/or required key missing - tainting kernel
[ 812.711656] module nvidia: unsupported RELA relocation: 275
[Fix]
a257e02579e42 arm64/kernel: don't ban ADRP to work around Cortex-A53 erratum #843419
[Regression Risk]
Regressions would most likely impact the loading of modules. To mitigate this risk, I've tested on a couple different arm64 servers - including loading of some the largest available modules - and have not seen any issues. All code changes are restricted to arm64, except for a new macro & #include in the generic linux/sizes.h header.

This bug is awaiting verification that the 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- bionic' to 'verification- done-bionic' . If the problem still exists, change the tag 'verification- needed- bionic' to 'verification- failed- bionic' .
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!
