        * LinkmapBuilder.java (getString): Rewrite. Simplify.

        * LinkmapBuilder.java: Reformat file.


2007-08-28  Phil Muldoon  <pmuldoon@redhat.com>

        * LinuxProc.java (constructEnhancedMapMetadata): Pass in base address
        from linkmap.
        * LinkmapBuilder.java (getString): New. Construct filename from address.
        (construct): Move linkmap lib string construction to getString.
        * SOLibMapBuilder.java (construct): Pass in new base_address.
        If base_address + vaddr = 0, discard mapping.
        (openElf): Sanity check the file.

2007-08-28  Phil Muldoon  <pmuldoon@redhat.com>

        * LinuxProc.java (getLinkmapAddress): Do not call getMemory(). Create
        own temporary instance of CorefileByteBuffer.
        (constructEnhancedMapMetadata): Ditto.

2007-08-24  Phil Muldoon  <pmuldoon@redhat.com>

        * LinuxProc.java (constructEnhancedMapMetadata): Remove vdso
        labelling from here to ...
        (constructBasicMapMetadata): .... Here.
        * ChangeLog. Fix typos and email for last entry.
