Subject: perf report: Use kernel_maps__find_symbol as fallback to find vdsos, etc
X-Git-Tag: v2.6.33-rc1~399^2~1^2~29
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=c3b32fcbc7f4fd9a9b84718b991b175b0fd53f8c;p=~emulex%2Finfiniband.git

perf report: Use kernel_maps__find_symbol as fallback to find vdsos, etc

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.
