get_page_shift() doesn't appear in the upstream kernel, so this is
some patch from OFED breaking things I guess. Does the test work with
an unpatched kernel?
This is Eli's hpages.patch. But that should only be applied
if enabled explicitly by install option. How come you get it?
Vlad?
When i removed the patch locally and executed the test, the function
get_user_pages failed.
The return value was -14 (EFAULT: bad address).
Does it mean that this address cannot be registered?
