Subject: [PATCH] perf symbols: Avoid unnecessary symbol loading when dso list
 is specified
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

We were performing the full thread__find_addr_location
operation, i.e. resolving to a map/dso _and_ loading its symbols
when we can optimize it by first calling thread__find_addr_map
to find just the map/dso, check if it is one that we are
interested in (passed via --dsos/-d in 'perf annotate', 'perf
report', etc) and if not avoid loading the symtab.

Nice speedup when we know which DSO we're interested in.
