The intent seems to be zeroing all of the cc_cpu array, or its singleton on
such platforms. The assumption made is that (1), the BSP is always zero
(true enough), and (2), that passing a pointer of limited scope (element
zero) to memset() will correctly zero the entire array, rather than invoke
nasal demons.
So, more succinctly, the expression could be: memset(cc_cpu,0,sizeof(cc_cpu)).
However, there's no point. cc_cpu lives in the data section and has a zero
initial value already. So this revision just removes the line.
No functional change. Appeases a (false positive, ish) Coverity CID.
