The buildsystem tries to run arch/ia64/scripts/unwcheck.py using "python", which on my system happens to point to python3. Hence unwcheck.py should be executed using python2 instead. Attached patch fixes this.
An even better way would probably be to mark the script executable and run it directly, without specifying in the Makefile which Python interpreter to use.
Has anyone had a look at this? It persists in 3.7.8.

Patches need to go to the maintainer of the tree, and possibly cc email@example.com, along with a Signed-off-by:. The patch Signed-off-by is needed for audit purposes (See Documentation/SubmittingPatches).
IA64 isn't exactly the most mainstream build setup any more.
