[Crash-utility] crash version 4.0-4.11 is available

[Dave Anderson]

- Fix for task-gathering to handle the 2.6.24 pid_namespace-related
   changes to the kernel pid_hash array.  Without the patch, the crash
   session fails during initialization with the message "crash:  cannot
   gather a stable task list via pid_hash (500 retries)".

- Fix for "kmem -f <address>" and "kmem <address>" commands on
   x86 kernels, which may incorrectly indicate that the address is in
   the kernel's free page list.  Without this patch, if the address
   argument is a physical address over 4GB, or a page struct address
   referencing a physical address over 4GB, it is possible that the
   address would incorrectly be shown as being in the kernel's free
   page list.  (anderson at redhat.com)

- Fix for x86 "bt" command for active tasks in Egenera dumpfiles
   based upon LKCD version 7.  Without the patch, the starting points
   for the active task backtraces were erroneous.

- Fix for a potential segmentation violation during crash session
   initialization if a task's kernel stack has been completely overrun,
   corrupting its thread_info structure at the bottom of the stack.
   This could occur running against kernels from 2.6.8 through 2.6.18.
   With the patch, the suspect task will be reported during the task
   initialization sequence.  (anderson at redhat.com)

- Fix for "kmem -S" error message if a slab object is found in both
   a per-cpu list and on a slab's global free list.  Without the patch,
   the object address and cpu number values are flip-flopped in the
   error message.  (bob.montgomery at hp.com)
