[Crash-utility] crash version 4.0-4.12 is available

[Dave Anderson]

- Fix for the "kmem -n" command to handle the 2.6.24 kernel replacement
   of the "node_online_map" nodemask with its appropriate entry in the
   new "node_states[]" nodemask array.  Without the patch, the per-node
   zone data would not be displayed, and any commands depending upon
   the node table data would be affected.  (anderson at redhat.com)

- Fix for "kmem -p" on 2.6.24 x86_64 kernels that are configured with
   CONFIG_SPARSEMEM_VMEMMAP,  which use a virtually-mapped page struct
   array.  Without the patch, the virtual-to-physical translation of
   each page structure was invalid, and "kmem -p" would display invalid
   data.  This would also affect other commands as well, such as the
   output of "kmem -i", and the output of a "vtop" command on a mapped
   page address.  Also, the virtual base address of the region is now
   displayed by the "mach" command.

- Fix for the "dev" command's character device name string output to
   recognize the change of the name structure member from a pointer
   to an embedded string.  Without the patch, 2.6.16 and later kernels
   would display "(unknown)" character device names.

- Fix for the "kmem -[sS]" command to handle the 2.6.24 change to
   the CONFIG_SLUB kmem_cache structure, which re-worked the manner
   in which the per-cpu slabs get referenced.  Without the patch,
   the command would fail with several error messages of the type:
   "kmem: page_to_nid: invalid page: ffff81003993f4b0".

- Fix for the "kmem -[fF]" command to handle the 2.6.24 kernel change
   of the free_area struct, which replaced the singular linked list
   of pages with 5 (MIGRATE_TYPES) linked lists.  Without the patch,
   the command would fail with the error message: "kmem: unrecognized
   free_area struct size: 88".   (anderson at redhat.com)

- Fix for the "runq" command to handle the 2.6.24 kernel change to
   the CFS scheduler that introduced per-cpu init_cfs_rq structures
   for task group scheduling.  Without the patch, no queued tasks
   were displayed, because the rb_root of queued tasks was being
   taken from the embedded cfs_rq in each per-cpu runqueue.
