Randy Dunlap 5f0e3da6e1 alpha: convert u64 to unsigned long long
Convert alpha architecture to use u64 as unsigned long long.  This is
being done so that (a) all arches use u64 as unsigned long long and (b)
printk of a u64 as %ll[ux] will not generate format warnings by gcc.

The only gcc cross-compiler that I have is 4.0.2, which generates errors
about miscompiling __weak references, so I have commented out that line in
compiler-gcc4.h so that most of these compile, but more builds and real
machine testing would be Real Good.
