Hi,

When trying to compile 2.6.16.11 on an alpha I encountered a compile
error in arch/alpha/kernel/setup.c. I found that the problem appears with
all kernels from 2.6.16.6 up to 2.6.16.11.
2.6.16.5 compiles fine, just like all older 2.6.16 -releases.
I did not test this with 2.6.17-rc -kernels.
The problem is that the version of the patch meant for the 2.6.17-rc
kernels was merged into 2.6.16.5. 'for_each_possible_cpu' does not
exist in the 2.6.16.x tree. Attached is a patch that replaces the usage
of for_each_possible_cpu with the 2.6.16 equivalent.
