Adding "protected_keys" tests to "run_vmtests.sh" would help out to run all VM related tests

Makes sense - can you explain why you can't just run
protection_keys_32 without checks?

Yes; we can run protection_keys_32 without check.


Why are you checking for VADDR64?

The check is added to ensure if the system is in 64-bit mode before executing 64-bit binary.



Okay. protection_keys_32 will only be built on 32-bit system and.
protection_keys_64 on 64-bit system.

On 64-bit system, we get both 32-bit and 64-bit binary.



Won't it be better to check if binary exists and run either _32 or
_64 instead of checking for VADDR64?

makes sense;

In this case on 64-bit platform we would run both _32 and _64 and this should be fine.



Okay - send v3 with the change.
