From: Kan Liang <kan.li...@intel.com>
This reverts commit 50e200f07948 ("perf tools: Default to cpu// for
events v5")
The fixup cannot handle the case that
new style format(which without //) mixed with
other different formats.
For example,
group events with new style format: {mem-stores,mem-loads}
some hardware event + new style event: cycles,mem-loads
Cache event + new style event: LLC-loads,mem-loads
Raw event + new style event:
cpu/event=0xc8,umask=0x08/,mem-loads
old style event and new stytle mixture: mem-stores,cpu/mem-loads/
