2014-09-26Docs: this_cpu_ops: remove redundant add formsMark Rutland1-2/+0
Commit ac490f4dca94 (Documentation: this_cpu_ops.txt: Update description of this_cpu_ops) added lists of {__,}this_cpu operations, but these have duplicate, parameter-less entries for {__,}this_cpu_add which don't correspond to any implementation. No other operations have such duplicate entries. Given both are also listed with their full complement of arguments, the empty forms are redundant and can be removed. This patch performs said removal.
