The sanest way to do that would probably be something along the lines of:

-> Change include/asm-xxx to arch/xxx/include/asm
-> Create arch/generic
-> Make sure arch/xxx/include/asm and arch/generic/include/asm are both 
in the include path, in that order.

That would also get rid of the symlink.

On the other hand, the redirection isn't all that bad.
