Hi Ralf, A few exported symbols in MIPS-specific code can be unexported, and this series of patches does so. This series was tested using a custom config that was produced by running `make allmodconfig', after which the CONFIG_VORTEX option was manually turned off. The patches I am submitting do not touch the code affected by this option, however. Setting this options on leads to unbuildable kernel independently of whether the patches are applied. Additionally, the entire patchset was tested at runtime by booting the Malta 4Kc board up to the shell prompt and inserting the `oprofile.ko' kernel module. The tests were successful. Thanks, Dmitri
