This all looks correct to me - it really shouldn't make any difference
to ia64 whether we use "long" or "long long" ... both are 8-byte entities.
The compiler would complain in some places if you mixed & matched
incorrectly (e.g. printk("val = %ld\n", val); will give a warning if val has
been switched from "long" to "long long" and the format would need
to change to "%lld"). But it looks like nothing like that happens as a
result of this patch. All my ia64 configs build with no new warnings.
Boots OK too.
