[PATCH 1/2] perf symbols: Set dso->kernel when handling the fake vmlinux MMAP event

From: Arnaldo Carvalho de Melo
Date: Tue Jan 19 2010 - 07:36:40 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

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.
