On the other hand non highmem platforms are burdened with always repeating

standard functions use KM_USER0 for their operations?
Couldn't that be filtered out inline?
It is - there is no runtime overhead for non-highmem machines.
The problem nowadays is all the developers who don't need, have, compile
for or test on highmem machines.
Well sure, if that's all Christoph is worried about, then it isn't
really valid because in generic code we have to follow the architecture
abstraction API -- there is no "non highmem platform" in generic code :)
