KDB (Linux Kernel Debugger) has been updated.

ftp://oss.sgi.com/projects/kdb/download/v4.4/

Current versions are :-

  kdb-v4.4-2.6.6-common-1.bz2
  kdb-v4.4-2.6.6-i386-1.bz2
  kdb-v4.4-2.6.6-ia64-1.bz2

There are some user and developer changes in this release, hence the
bump from kdb v4.3 to v4.4.

User visible changes:

  The sequence to enter kdb from a serial console is now <escape>KDB.
  The old <control>A sequence caused problems for people using editors
  and GNU readline over a seral link.  Edit kdb_serial_str in
  kdb/kdbmain.c if you do not like <escape>KDB.

  New summary command.

  The cpu command distinguishes between cpus that are in kdb control,
  cpus that have some kdb data but are not in kdb control ('+') and
  cpus with no kdb data ('*').  Also the format of the output has
  changed, to make it more readable on big systems.

  New process states, 'I' for idle and 'M' for sleeping system daemons.
  By default tasks in states I and M are not printed, they rarely
  contribute anything to problem diagnosis.  Use ps IM or ps A to see
  them.

  dmesg can print any part of the log, not just the end.

  The md command will suppress a run of zeroes.

  Section data is suppressed by default.  Pity, it can be useful when
  debugging modules, but the in kernel module loader in 2.6 does not
  maintain section data.

Developer visible changes:

  arch/$(ARCH)/kdb/{ansidecl,bfd}.h have been moved to include/asm-$(ARCH).
  Makefiles used to add -I $(TOPDIR) arch/$(ARCH)/kdb to CFLAGS, this
  is no longer required.  #include "bfd.h" or "ansidecl.h" replaced by
  <asm/bfd.h> and <asm/ansidecl.h>.

  Some kdb fields have moved from kdb.h to kdbprivate.h.  You need to
  use #include <linux/kdbprivate.h> in code that uses kdb internals.

  If you maintain an architecture specific kdb patch, please upgrade to
  kdb v4.4 and send it to me.
