[Crash-utility] crash version 4.0-2.31 is available

- Bumped crash-internal NR_CPUS for x86 and ia64; added a warning message to "recompile crash" and forced an initialization failure when the kernel's configured NR_CPUS is greater than the maximum allowed NR_CPUS value compiled into crash. (maneesh(a)in.ibm.com, anderson(a)redhat.com) - Fix for initialization failure indicating a kernel/memory-source mismatch when x86 kernel configures its physical memory start address higher than the traditional 1MB starting point. (anderson(a)redhat.com) - Fix for kernels that have replaced the "system_utsname" data structure with contents of the "init_uts_ns" data structure. This fixes a "crash: cannot resolve system_utsname" initialization failure. (pbadari(a)us.ibm.com, anderson(a)redhat.com) - Fix for large LKCD dumpfiles that resulted in an initialization time failure indicating "fixme, need to add more zones (ZONE_ALLOC)". When statically-defined ZONE_ALLOC value is too small, the fix expands the zone size dynamically. (indou.takao(a)jp.fujitsu.com) - Fix for "kmem -i" failure when the "all_bdevs" block_device list is empty. Part of the command output would be displayed, followed by "kmem: invalid kernel virtual address: 0 type: inode buffer". (anderson(a)redhat.com) - First pass at supporting a xen hypervisor kexec/kdump vmcore as the dumpfile format for the dom0 vmlinux. Developed/tested OK on an x86 vmlinux/vmcore set supplied by horms(a)verge.net.au. Code for x86_64 is in place, but untested. (anderson(a)redhat.com) - Also in place, but untested, is initial support for xen x86 PAE kernels. (anderson(a)redhat.com) Download from: http://people.redhat.com/anderson
