--- Comment #5 from Dmitry Torokhov (dmitry.torokhov@gmail.com) ---
32 pages for a single field suggests that there is a garbage in the descriptor
and blindly converting to kvmalloc_array() is indeed simply papering over the
problem.
I suggest you post hid report descriptor and maybe instrument
hid-core.c::hid_register_field() to see what number of usages and values it is
being asjed to allocate.
