[PATCH v3 0/9] Fix BZ 25631 - core file memory access problem

[Kevin Buettner <kevinb@redhat.com>]

Nick Clifton has approved patch #1.  It hasn't changed since approval.

I think that Pedro is okay with patch #2, #4, and #5.  They haven't
changed for this v3 series.

I made the updates that Pedro requested for patch #3, but it should
probably be reviewed again just to make sure that I didn't mess
anything up.

Patch #6 is new, but it will need approval from a binutils maintainer. 
I'll attempt to CC it to that list.

Patch #7 is new and will definitely require careful review.

Patches #8 and #9 are also new.  They add new tests for the cases
which #7 now handles.

So, in summary, patches #3, #7, #8, and #9 should be reviewed by a GDB
maintainer.  Patch #6 requires approval by a binutils maintainer.

Kevin Buettner (9):
  1) Remove hack for GDB which sets the section size to 0
  2) Adjust corefile.exp test to show regression after bfd hack removal
  3) section_table_xfer_memory: Replace section name with callback
     predicate
  4) Provide access to non SEC_HAS_CONTENTS core file sections
  5) Test ability to access unwritten-to mmap data in core file
  6) Update binary_get_section_contents to seek using section's file
     position
  7) Use NT_FILE note section for reading core target memory
  8) Add test for accessing read-only mmapped data in a core file
  9) New core file tests with mappings over existing program memory
