* Cherry-pick upstream commits: - [PATCH] BUGFIX: Avoid SIGSEGV when specifying -V option. (5b8c2da75cbdb230019a3b956793fb768055b977) - [PATCH] Copy correct nr_cpus info to dumpfile during re-filtering. (c4f1c98a9827c1c0e41772c1954940fbf1b48048) * kdump-tools.init: Don't exit with failure status except for bad usage. This way, even if /etc/default/kdump-tools has USE_KDUMP=1 but the kernel command line or debug kernels are not set up, installation of a new version of the package will not leave it unconfigured. (Closes: #623470)
