File kdump-use-last-entry-get-mountpoints.patch of Package kdump

From: Roberto Sassu <rsassu@suse.com>
Subject: Use the last mount entry in kdump_get_mountpoints()
References: bsc#951844
Patch-mainline: v0.8.16
Git-commit: 07e26e637e6c98bf977fa3d5f1ee0902ded8e100

When a mount point appears multiple times in /proc/mounts and/or
/etc/fstab, then the last occurence should be taken. This is
especially important to avoid including the rootfs entry (if
"/" is missing in /etc/fstab).
