According to grep I see no users:
| #git grep inttest
| Documentation/kernel-parameters.txt: inttest= [IA-64]
The parameters itself has no description what it supposed to do.
According to the history tree, it was introduced in "[PATCH] Updated
Documentation/kernel-parameters.txt" ("
10414c6ddb"). By that time that
parameter had an user. It was removed later by "[PATCH] ia64: SGI SN
update" ("
c6bacd5010ec") by Jesse Barnes himself.
