Hi Gautam,

This patch doesn't seem to resolve the issue where numbers are seen instead of hcalls.
I have applied to the latest upstream but the numbers are still visible in perf script.
Also the command doesn't recognise python-audit already present in the system.

Please find logs below for better understanding.
