When creating fstab for kdump bind mounts the dump and fsck fields are not
specified. These should be 0 because the directory which is bind-mounted cannot
be checked nor dumped.

Freeing fadump memory can take a long time and doing it when we are going to
reboot anyway is pointless.
In bsc#1034169 a kernel oops is triggered by freeing fadump memory killing
save_dump.sh and preventing the reboot requested by the user from happening
entirely.
Avoid the issue and speed up reboot by not freeing fadump memory when reboot is
requested.

Git-commit: 81899709e4a12bea4819d4ccc10f960cb535b447
When using NPIV with LUN autoscan, dracut does not save the port and
LUN information. However, LUN autoscan is always disabled in kdump
environment, so the LUNs will never appear.
To fix this case, the full information must be saved explicitly in a
kdump initrd.

Subject: Fix save_dump to NFS targets
References: bsc#1045541
Upstream: v0.8.17
Git-commit: 11d36a645ab99c9805f9fa3ca9eabce3aa2a9418
For NFS, the parent directory of the target must be mounted, because
the target directory itself does not exist yet.
For this to work, split the target path to directory (i.e. parent
directory) and basename. Then construct a unique mount point from the
host name and the parent directory, and finally append the base name
again to form a subdirectory in the target (to be created by the file
transfer method).

The "--num-threads" and "--split" makedumpfile options are mutually
exclusive. Before multithreading was implemented, "--split" was the
only way to use any additional CPUs. It makes more sense to use
multithreading by default.
To use "--split", the SPLIT flag can be specified.

Subject: Remount /sysroot readwrite when used for kdump
References: bsc#1034169
Upstream: v0.8.17
Git-commit: b3e40e6cb5794e441ddabf1de88f3729ebd0cc6f
When kdump is saved to / (ie /var is not separate filesystem) /kdump/mnt0 is
bind mount of readonly /sysroot. Due to mount bug "mount /kdump/mnt0 -o
remount,rw" does nothing.
Remount the device by hand with "mount none /kdump/mnt0 -o remount,rw" which
avoids the bug.

save_dump.sh is designed to be sourced and contains a number of toplevel return
statements. Bash will complain when these are executed unless the script is
sourced so source it to prevent useless noise.

Since SMP after crash is now considered stable, remove the warnings and
make the feature more useful by not requiring a fixed number of CPUs.
