+ 
+ [ Fix ]
+ 
+ Enable arm64 backporting the following patch from upstream:
+ - 
https://github.com/falcosecurity/libs/commit/c4f096099bf81966803d26c40c6c2cb2b8d08033
+ 
+ [ Test Plan ]
+ 
+ Install and load sysdig driver on both Jammy generic and Jammy hwe on
+ arm64:
+ 
+ $ sudo apt install sysdig-dkms
+ $ dkms status
+ $ sudo modprobe sysdig-probe 
+ $ lsmod | grep sysdig
+ 
+ [ Regression potential ]
+ 
+ We may experience regressions in systems that are using sysdig in Jammy.
