           It is also possible to run FDPIC ELF binaries on MMU linux also.

+          ELF core dump files describe each memory mapping of the crashed
+          process, and can contain or omit the memory contents of each one.
+          The contents of an unmodified text mapping are omitted by default.
+
+          For an unmodified text mapping of an ELF object, including just
+          the first page of the file in a core dump makes it possible to
+          identify the build ID bits in the file, without paying the i/o
+          cost and disk space to dump all the text.  However, versions of
+          GDB before 6.7 are confused by ELF core dump files in this format.
+
+          The core dump behavior can be controlled per process using
+          the /proc/PID/coredump_filter pseudo-file; this setting is
+          inherited.  See Documentation/filesystems/proc.txt for details.
+
+          This config option changes the default setting of coredump_filter
+          seen at boot time.  If unsure, say N.
