[Greg Kroah-Hartman]

4.5-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 569cc39d39385a74b23145496bca2df5ac8b2fb8 ]

llvm cannot always recognize memset as builtin function and optimize
it away, so just delete it. It was a leftover from testing
of bpf_perf_event_output() with large data structures.
