Subject: [PATCH] perf report: Use kernel_maps__find_symbol as fallback to find
vdsos, etc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
In resolve_symbol, as we're moving to breaking the kernel symbols
list per address ranges, i.e. kernel linking sections, so that we
don't have a big kernel_map that in its range covers what is in the
modules.
