[PATCH] unexport register_cpu and unregister_cpu

[Nathan Lynch <nathanl@austin.ibm.com>]

http://linus.bkbits.net:8080/linux-2.5/cset@4180a2b7mi2fzuNQDBOQY7eMAkns8g?nav=index.html|src/|src/drivers|src/drivers/base|related/drivers/base/cpu.c

This changeset introduced exports for register_cpu and unregister_cpu
right after 2.6.10.  As far as I can tell these are not called from any
code which can be built as a module, and I can't think of a good reason
why any out of tree code would use them.  Unless I've missed something,
can we remove them before 2.6.11?

Build-tested for ia64 and i386.
