I tried that. Wrote a patch that defines KERNEL (in a 2nd attempt
__KERNEL__) before the inclusion of unistd.h. However it still could not
find __sys1. By looking at the particular header file I could not find
any declaration of this function.

The kernel headers are from Linux 2.6.20 btw.

Dalibor then pointed me to a solution that was used for software called

syscall(__ARM_NR_cacheflush, start, end, 0);

With that in place I got

kaffe-bin: exception.c:100: vmExcept_setJNIFrame: Assertion `fp !=
(JNIFrameAddress)0' failed.

at runtime. So it is probably not correct either. :(

I now found a cacheflush implementation in libffi. I adjust this for
kaffe and report back.
