[Crash-utility] crash version 4.0-4.8 is available

[Dave Anderson]

- Implemented support for kernels configured with CONFIG_SLUB, which
   completely replaces the venerable "kernel/slab.c" with the new
   "kernel/slub.c" kmalloc() slab subsystem.  Accordingly, the
   "kmem -s [address]", "kmem -S [address]", and "kmem <address>"
   commands will display slab-related information in a similar manner
   to what they currently do, with additional per-node information.
   It should be noted that, due to slub.c's design, the verbose
   "kmem -S" output will be pared down slightly to not display the
   list of all "full" slabs unless the proper kernel slub debugging
   has been turned on.  However, given a address of an object from a
   full slab page, or of the full slab page itself, that address
   will then be traced back to its original slab cache and its data
   displayed.  (anderson at redhat.com)

- Change for support of LKCD dumpfile version 8 and later to determine
   the backtrace starting registers from the dumpfile header.  Increase
   (maximum) NR_CPUS for ia64 to 4096.  (bwalle at suse.de)

- The SIAL interpreter extension module has been updated to support
   the ia64, ppc64, s390 and s390x architectures.  Several fixes have
   been applied, and three new debug commands, sdebug, sclass and sname
   have been added.  (lucchouina at yahoo.com)

- Fixed a bug in the CONFIG_SPARSEMEM patch (contributed in 4.0-3.22)
   in which a static pointer variable was initializing itself with a
   buffer that was returned from a command-time-only GETBUF() call,
   instead of using malloc().  It would then continue to use the buffer,
   trampling on the buffer contents set up by whatever command that
   subsequently allocated the buffer.  I only caught this during the
   CONFIG_SLUB development, so I have no examples (if any) of how this
   would have ever manifested itself in a crash command error.

- Fixed the "mach" command in CONFIG_SLUB kernels which would abort
   with the error message: "mach: cannot resolve cache_cache" when
   trying to determine the value for the L1 CACHE SIZE display.  Since
   the generic manner of determining the cache size no longer worked
   correctly anyway, the L1 CACHE SIZE display has been removed.

- Fix for missing NODE header in NUMA "kmem -f" output.

- Fix for the chronology of the contents of the kernel message buffer
   output by the "log" command.  (atyson at hp.com)

- Display a WARNING message if a PT_LOAD segment in an ELF-style
   dumpfile advertises a memory segment that would go beyond the end
   of the dumpfile.  (bwalle at suse.de, anderson at redhat.com)
