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

- 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(a)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(a)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(a)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. (anderson(a)redhat.com) - 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. (anderson(a)redhat.com) - Fix for missing NODE header in NUMA "kmem -f" output. (anderson(a)redhat.com) - Fix for the chronology of the contents of the kernel message buffer output by the "log" command. (atyson(a)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.
