I am upgrading the kernel of a linux-router from 2.4.21 to 2.6.22. The routing algorithm is a proprietary one. While compiling it with the new kernel, I got the following error:
Code:

/lib/modules/2.6.22.2/build/include/asm/processor.h:83: error: requested alignment is not a constant
In the 2.4.21 /lib/modules/`uname -r`/include/linux directory, skbuff.h is not included from if_ether.h, but in 2.6.22 it is. How should I tacle this error?
