- Fix for support of xendump and Xen kdump dumpfiles from 2.6.27 and and later x86_64 kernels. Without the patch, the crash session would fail during initialization with the error message "crash: cannot resolve end_pfn". (ptesarik(a)suse.cz) - Fix for the "s390dbf" command to allow the command's output to be redirected to a pipe. (holzheu(a)linux.vnet.ibm.com) - Fix for the x86 "bt" command to generically recognize the end of trace condition for tasks entering the kernel from user-space without having to hardwire any more kernel entry point function names. Without the patch, a task that took a clock interrupt from user-space and crashed while operating on the soft IRQ stack failed with the error message "bt: cannot resolve stack trace". (anderson(a)redhat.com) - Display the "machine type mismatch" warning when attempting to use a ppc64 vmlinux file on a non-ppc64 64-bit host. Without the patch, the fact that ppc64 vmlinux ELF files are type ET_DYN, and not type ET_EXEC like all of the other architectures, was allowing the vmlinux to be accepted without the mismatch warning, and would subsequently fail without a meaningful explanation being displayed. (anderson(a)redhat.com) - Fix for the x86_64 "bt" command if the kdump-generated NMI interrupts a multi-threaded task that has just entered kernel space but has not changed the RSP stack pointer register from its user-space per-thread stack location to the kernel stack. Without the patch, the command follows the display of the exception frame on the NMI exception stack with the message "WARNING: possibly bogus exception frame", displays the error message "bt: cannot transition from exception stack to current process stack", and does not display the user-space exception frame. (anderson(a)redhat.com) - Added the "set" command to the list of commands acceptable when running in --minimal mode. The command is limited to the setting of internal variables since there is no task context in that mode. (anderson(a)redhat.com) - Fix for the "vtop" command when run against x86 Xen PAE kernels. Without the patch, the "PAGE:" displays (machine and pseudo-physical) contained non-zero values in the lower 12 bits, and the translation of the PTE entry was incorrect as a result of receiving the incorrect contents in the lower 12-bits of the PTE entry. (anderson(a)redhat.com) - Implemented support for running against live x86_64 pv_ops/Xen guest kernels. (anderson(a)redhat.com) - Implemented support for xendump ELF dumpfiles generated from x86_64 pvops/Xen guest kernels. (anderson(a)redhat.com) - Implemented support for running against live x86 pv_ops/Xen guest kernels. (anderson(a)redhat.com) - Implemented support for xendump ELF dumpfiles generated from x86 pvops/Xen guest kernels. (anderson(a)redhat.com) - Determine the bit positions of PG_reserved and PG_slab using the newer pageflags enumerator values if available. (anderson(a)redhat.com) - Fix to prevent the "repeat" command from keeping a crash session alive if the controlling terminal session is killed.
