Please have a look at this thread:

  http://lists.arm.linux.org.uk/lurker/message/20090123.185306.b2c4bb05.en.html

Conclusion is: do not build your kernel using a compiler that generates
iwmmxt code. As these extensions can't be used from both the kernel and
userspace at the same time, it is reserved for user's binaries and hence
forbidden in the kernel.
