For large machine, suppose there's a lot of multipath devices, multipath layer
will use a lot of memory. For kdump kernel memory is very limited thus it causes
oom. To avoid oom, we only add necessary multipath devices in kdump kernel
multipath.conf.
This is done by use mpathconf --allow, a new option which is like whitelist.

"ifup -m" was thought to be used by humans in the emergency shell.
Using it programatically shows some other flaw in the execution logic.
Also, "ifup -m" was configuring the interface multiple times on "add"
and "change" uevent, because the "$netif.did-setup" test was not
executed.
This reverts commit cfa365a32d.
The logic in commit cfa365a was added to prevent (odl) lvms from
activating snapshots which should not be activated.
Newer lvms however do this automatically (not enabling an LV if the
the 'k' attribute set), thus we can revert the previous commit.
openSUSE has things stored in different places, so fixup the
paths here.

The fcoe-uefi module should test for EFI firmware when called
in 'hostonly' mode; of no EFI firmware is found then the module
doesn't need to be included.

When systemd's crypttab generator parsed crypttab, it tells
systemd about several devices which may not appear until later
in the boot sequence, and which are not needed while dract is running.
This can particularly happen when an md array is encrypted,
and the array is newly degraded so that it doesn't appear until
dracut runs mdraid_start.sh.
This can result in systemd printing warning messages which are
inappropriate.
So tell systemd that the timeout for each of these is zero.
This is involves splitting some functionality out of wait_for_dev()
That function does two things:
- creates 'finished' hooks so that dracut will wait for the device,
and
- sets the systemd timeout for the device to zero, so systemd doesn't
wait.
We only want the second of these for most encrypted devices.
So split that out into a new function set_systemd_timeout_for_dev(),
and call it from parse-crypt.sh

dracut: Make host only mode more resilient to missing swaps.
This patch set allows swap devices to disappear without cocking up a
host-only initramfs boot.
