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

- 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)". (anderson(a)redhat.com) - 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(a)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. (anderson(a)redhat.com) - 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(a)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(a)hp.com) Download from: http://people.redhat.com/anderson
