iwl + iomap + readl/writel

Hi,

I spotted that iwl drivers use readl method on an iomap space. IIRC some archs might return a tag instead of an address expected by readl/writel.

I think you should either switch to ioread32/iowrite32 or to ioremap.

Can you give me reading material on this?

No, google will (you can even feel lucky).

I didn't ask for obvious answers :)

Sorry, I don't remember where/when this was discussed, you have to search for it.
