Subject: perf symbols: Set dso->kernel when handling the fake vmlinux MMAP event
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f162f87ad6e98e8bfb2362955da46bed7b2514be;p=openwrt%2Fstaging%2Fblogic.git

perf symbols: Set dso->kernel when handling the fake vmlinux MMAP event

Because it may be possible that there was no buildid section,
where we would set this to 1.

Found while analysing a perf.data file collected on an ARM
machine where an explicitely specified vmlinux was being
disregarded.
