[Crash-utility] crash version 4.0-4.2 is available

- Fix for support of 2.6.22 kernels, which have changed the name of the task_struct's "thread_info" member to the "stack" member. This would cause the crash session to fail during initialization. (troy.heber(a)hp.com, anderson(a)redhat.com) - Fix to account for the number of pgdata nodes being less than the number of cpus. Without the patch, the crash session would fail during initialization with the error message: "crash: numnodes out of sync with pgdat_list?" (sharyath(a)in.ibm.com) - Implemented support for ia64 dom0/HV kdump dumpfile support, taken either via the traditional kdump process, or simulated via the Fujitsu "sadump" facility. (oda(a)valinux.co.jp) - Created a "--no_panic" command line option to avoid the panic-task search during initialization. (anderson(a)redhat.com) - Implmented a new "ps -r" option to display resource limits (ulimits): crash> ps -r 20618 PID: 20618 TASK: 1003cb82030 CPU: 1 COMMAND: "bash" RLIMIT CURRENT MAXIMUM CPU (unlimited) (unlimited) FSIZE (unlimited) (unlimited) DATA (unlimited) (unlimited) STACK 10485760 (unlimited) CORE 0 (unlimited) RSS (unlimited) (unlimited) NPROC 8180 8180 NOFILE 1024 1024 MEMLOCK 32768 32768 AS (unlimited) (unlimited) LOCKS (unlimited) (unlimited) SIGPENDING 1024 1024 MSGQUEUE 819200 819200 (anderson(a)redhat.com) - Implement support for the registration of CLEANUP extension commands that do not show up in help menu, but get called by restore_sanity(). Extension modules may also register HIDDEN_COMMAND functions; and the "help -e" debug output has been enhanced. (anderson(a)redhat.com) - Implemented a new symbol_value_module() primitive, primarily for use by extension modules to quickly access the address of a module symbol in cases where a name-clash may exist between the base kernel and/or other modules. (anderson(a)redhat.com) - The crash-4.0-4.2.src.rpm package will create an additional package named crash-devel-4.0-4.2.i386.rpm, which is for use by extension modules. The -devel package installs the top-level "defs.h" file in "/usr/include/crash/defs.h". (anderson(a)redhat.com) Download from: http://people.redhat.com/anderson
