commit e5a16a5c4602c119262f350274021f90465f479d upstream.
test_bit(), as any other bitmap op, takes `unsigned long *` as a
second argument (pointer to the actual bitmap), as any bitmap
itself is an array of unsigned longs. However, the ia64_get_irr()
code passes a ref to `u64` as a second argument.
This works with the ia64 bitops implementation due to that they
have `void *` as the second argument and then cast it later on.
This works with the bitmap API itself due to that `unsigned long`
has the same size on ia64 as `u64` (`unsigned long long`), but
from the compiler PoV those two are different.
Define @irr as `unsigned long` to fix that. That implies no
functional changes. Has been hidden for 16 years!
