Public bug reported:

[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.
