Hi,

This patch is needed in order to compile kernel modules that uses some
of the DCR functions. For example, compiling powerpc emac driver as
module it is needed.

Arnd, Dennis Spathis pinged me about this today and I thought it was a
closed issue but still open. If you find it okay please upstream it or
let me know if any modifications needed. Thanks.

Subject: Export few DCR symbols for kernel modules

In order to compile drivers as modules that uses some of the
DCR functions, we need to export the symbols. Example, EMAC
driver and other drivers that are under development uses these
some of the functions.

This patch applies cleanly against 2.6.23-rc1 kernel and ready
for inclusion.
