How about this patch?  This is almost the original macro in riva_hw.h,
with the __force annotation.

Why not just use __raw_readl/__raw_writel?

That's what they exist for, and they still do any IO accesses correctly, 
which a direct store does not do (it would seriously break on older 
alphas, for example).

sorry for a dumb question but should readl/writel on big endian system
swap like ppc does?

hmm... checking source code, it seems like most arch indeed does that,
except m68knommu, h8300 and microblaze. is it nommu thing?
