Handle memory maps generated by logging
Handle memory maps generated by logging

If the memory map is generated by logging routines such as glog, they
may include some initial text which confuses the parsing of legacy
mappings. The initial text is the same for all mapping entries,
so detect it on the proc map sentinel and remove it from the mapping
entries.
