bootgraph: fix for use with dot symbols

mikey · sravnborg · commit 0bb98e231803 · 2009-02-15T12:50:08.000+01:00
powerpc has dot symbols, so the dmesg output looks like:

&lt;4&gt;[    0.327310] calling  .migration_init+0x0/0x9c @ 1
&lt;4&gt;[    0.327595] initcall .migration_init+0x0/0x9c returned 1 after 0 usecs

The below fixes bootgraph.pl so it handles this correctly.
