Denys Vlasenko eed4a2aba7 printk.c: use unsigned ints instead of longs for logbuf index ...

Stop using unsigned _longs_ for printk buffer indexes.  Log buffer is way
smaller than 2 gigabytes and unsigned ints will work too .  Indeed, they do
work nicely on all 32-bit platforms where longs and ints are the same.

With this patch, we have following size savings on amd64:

   text    data     bss     dec     hex filename
   5997     313   17736   24046    5dee 2.6.23.1.t64/kernel/printk.o
   5858     313   17700   23871    5d3f 2.6.23.1.printk.t64/kernel/printk.o
