Oh can you elaborate more on the issue? I bet if we merge it that way, someone
comes around with a patch chaning it to writeq() on 32Bit as well.

Wouldn't it be better to improve the 32Bit writeq() code?

Generally speaking (same for the WC issue), ifdefs (especially architecture
specific ones) in driver code should be avoided.
