My udelay is already global-variable-free. And as for cycles_per_jiffy and expirelo, we could make it work like this:

If it's a constant anyway - then why do we need a variable for it?
Of course, we don't. That was for easy review, will fix.
But I have no clue about timestamp.
Maybe there is a register that is (1) common to all or at least most of the supported processors we could use for that? If not, then we
I'm afraid there's not such register left.
probably have to use the initial data structure for this.
Looked around board_init_r, and it seems there is no {set,get}_timer user there. I'm going to leave timestamp as it is at this moment.
