How to printk/sprintf uint64_t on Sparc without format and argumenttypes mismatch

[Vladislav Bolkhovitin]

Hello,

We in SCST project need to printk/sprintf variables of type uint64_t. 
Size of those variables is required to be 64-bit integer. On x86 we 
printk/sprintf them as %lld, but on Sparc we have a compiler warnings like:

scst/src/scst_targ.c:2136: warning: format ‘%llx’ expects type ‘long 
long unsigned int’, but argument 4 has type ‘uint64_t’.

It is because on Sparc uint64_t defined as unsigned long, but on x86 - 
as unsigned long long.

Sure, we can cast all the cases to unsigned long long, but we wonder, 
maybe there is a more elegant way to do that without the warning? For 
instance, like %z for size_t or PRId64 in the user space.

Thanks,
Vlad
