In gcc-13, the WORK_STRUCT_WQ_DATA_MASK constant is a signed 64-bit
type on 32-bit architectures because the enum definition has both
negative numbers and numbers above LONG_MAX in it:
kernel/workqueue.c: In function 'get_work_pwq':
kernel/workqueue.c:709:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
709 | return (void *)(data & WORK_STRUCT_WQ_DATA_MASK);
| ^
kernel/workqueue.c: In function 'get_work_pool':
kernel/workqueue.c:737:25: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
737 | return ((struct pool_workqueue *)
| ^
kernel/workqueue.c: In function 'get_work_pool_id':
kernel/workqueue.c:759:25: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
759 | return ((struct pool_workqueue *)
| ^
Change the enum definition to ensure all values can fit into
the range of 'unsigned long' on all architectures.
