[PATCH 04/21] perf script: Fix symoff printing in callchains

From: Arnaldo Carvalho de Melo
Date: Mon Dec 09 2013 - 14:43:55 EST


From: Adrian Hunter <adrian.hunter@xxxxxxxxx>

The address being used to calculate the offset was the memory address
but the address needed is the address mapped to the dso. i.e. the 'addr'
member of 'struct addr_location'
