ia64, processor: fix -Wincompatible-pointer-types in ia64_get_irr()
commite5a16a5c46
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! Fixes:a58786917c
