perf symbols: Fixup vsyscall maps
While debugging a problem reported by Pekka Enberg by printing
the IP and all the maps for a thread when we don't find a map
for an IP I noticed that dso__load_sym needs to fixup these
extra maps it creates to hold symbols in different ELF sections
than the main kernel one.
Now we're back showing things like:
[root@doppio linux-2.6-tip]# perf report | grep vsyscall
0.02% mutt [kernel.kallsyms].vsyscall_fn [.] vread_hpet
0.01% named [kernel.kallsyms].vsyscall_fn [.] vread_hpet
0.01% NetworkManager [kernel.kallsyms].vsyscall_fn [.] vread_hpet
0.01% gconfd-2 [kernel.kallsyms].vsyscall_0 [.] vgettimeofday
0.01% hald-addon-rfki [kernel.kallsyms].vsyscall_fn [.] vread_hpet
0.00% dbus-daemon [kernel.kallsyms].vsyscall_fn [.] vread_hpet
[root@doppio linux-2.6-tip]#
