So you think that adding this to mmio.c is the solution to the problem?
Ever heard about function prototypes, header files and such?

So now we have three global functions which provide access to the mmio clocksource. And one of them is always redundant for a given compile time endianess. You can't be serious about this...
But ... wait, I've seen enough qualitee code from Fleascale in the past 10 years, so you actually might be serious about it.
JFYI: You are trying to submit code to the public maintained codebase of the Linux kernel, not to some random sh^H^Hgit repository inside of Fleascale which accepts any random amount of crap. Can you see the difference?
I can see it rather clearly.
Thanks,
tglx
