This only affect the hardware IO layer of some cards and I think
it will be fixed very soon, I did not remove the very old
#error line, because I did not had the hardware to verify that it is
OK now.
I already reserved a PPC machine now (will get it today or tomorrow) and
will test the endian robustness this week.

This was my original plan and my fault, that I only included the
pull URL and sent it to Linus diectely, I did not know that in this case
Linus will pull it without further discussion, but I'm still glad that it
is in and only show few issues (I'm very unhappy that I did not find
these before, I did builds on all our architectures, but not with the
all*config, only with subsets).
The good thing is, that this brought back the ENDIAN issue back on my
radar and on my near time TODO list :-)
