This whole issue of printk vs. resource_size_t is a terrible mess :-(
Part of the problem is that resource_size_t can be either u32 or u64..
that is it can be either unsigned int, unsigned long or unsigned long
long... and we have no way to reliably printk that.
Any clever idea before I start pushing filthy macros up linux/types.h ?
Cheers,
Ben.
