File kdump-skip-mounts-if-no-proc-vmcore.patch of Package kdump.13716

From: Petr Tesarik <ptesarik@suse.com>

Subject: Skip kdump-related mounts if there is no /proc/vmcore
References: bsc#1102252, bsc#1125011
Upstream: merged
Git-commit b91c1e16d373e5631ce725acf52db097d8248389

With FADUMP, the same initrd is used for saving a dump and for
normal boot. It is not necessary to mount kdump-related filesystems
on a normal boot, so let's add a systemd condition.
