Do these new macros really buy anything over just writing LL in the

The original workaround was to make the offending *SEC_TO_HZ_ADJ32
constants use "ULL" suffixes. Certainly making the Perl script emit
those would be less intrusive.


"Less intrusive" in the sense of smaller line count for this particular patch, perhaps, but it makes it less obvious when reading the code what's going on (a size override in an entirely different file). Additionally, I'm hoping these kind of things can be used elsewhere; the C99 <inttypes.h> facilities are really quite nice once you get over the rather ugly look of them, and I for one definitely miss having access to the in the kernel.
