Add check for aarch64 to the arm kernel module list
This adds the same list of drivers we use for arm platforms for
aarch64 too, also add the DMA drivers there too as they can add
sigficant performance for some storage/usb and often need to be
present when the storage drivers load.

dmsquash-live-root: Provide enhanced feedback on missing overlay.
Provide a more prominent alert to the user if an overlay is
missing or the overlay module is not available and a temporary
overlay will be provided. This, to avoid losing data intended to

Enable the use of the OverlayFS for the LiveOS root filesystem.
Integrate the option to use an OverlayFS as the root filesystem
into the 90dmsquash-live module for testing purposes.
The rd.live.overlay.overlayfs option allows one to request an
OverlayFS overlay. If a persistent overlay is detected at the
standard LiveOS path, the overlay & type detected will be used.
Tested primarily with transient, in-RAM overlay boots on vfat-
formatted Live USB devices, with persistent overlay directories
on ext4-formatted Live USB devices, and with embedded, persistent
overlay directories on vfat-formatted devices. (Persistent overlay
directories on a vfat-formatted device must be in an embedded
filesystem that supports the creation of trusted.* extended
attributes, and must provide valid d_type in readdir responses.)
The rd.live.overlay.readonly option, which allows a persistent
overlayfs to be mounted read only through a higher level transient
overlay directory, has been implemented through the multiple lower
layers feature of OverlayFS.
The default transient DM overlay size has been adjusted up to 32 GiB.
This change supports comparison of transient Device-mapper vs.
transient OverlayFS overlay performance. A transient DM overlay
is a sparse file in memory, so this setting does not consume more
RAM for legacy applications. It does permit a user to use all of
the available root filesystem storage, and fails gently when it is
consumed, as the available free root filesystem storage on a typical
LiveOS build is only a few GiB. Thus, when booted on other-
than-small RAM systems, the transient DM overlay should not overflow.
OverlayFS offers the potential to use all of the available free RAM
or all of the available free disc storage (on non-vfat-devices)
in its overlay, even beyond the root filesystem available space,
because the OverlayFS root filesystem is a union of directories on
two different partitions.
This patch also cleans up some message spew at shutdown, shortens
the execution path in a couple of places, and uses persistent
DM targets where required.

network/ifup: write override file before dhcp_do
Commit cf376023e6d0d4abd9816fa954bb917fc2557713 moved writing .resolv.conf and .override
after dhcp_do, because dhcp_do was overwriting .resolv.conf. But .override does not have
such problem and on the contrary dhcp_do reads .override file if it is present. So let\'s
move it back.

dracut.sh: add default path for --uefi
The default output filename for --uefi is
<EFI>/EFI/Linux/linux-$kernel$-<MACHINE_ID>-<BUILD_ID>.efi.
<EFI> might be /efi, /boot or /boot/efi depending on where the ESP partition
is mounted. The <BUILD_ID> is taken from BUILD_ID in /usr/lib/os-release or
if it exists /etc/os-release and is left out, if BUILD_ID is non-existant or
empty.
Also a new option --no-machineid was added, which affects the default output
filename of --uefi and will discard the <MACHINE_ID> part.
Some docs claimed that values in certain config files would be
overwritten, when they would actually be overridden.
Override: a file is not modified but its contents are superseded by
something else. (configurations set in
/etc/dracut.conf.d/*.conf override configurations set in
/etc/dracut.conf)
Overwrite: a file is modified or its contents replaced by an action
(use dracut --force to overwrite the existing initramfs)

95ssh-client: attempt to copy UserKnownHostsFile to kdump's initramfs
Bug related to this issue: https://bugzilla.redhat.com/show_bug.cgi?id=1360131
Now dracut only attempts to copy GlobalKnownHostsFile while generating kdump's
initramfs. This method will cause kdump's failure if users set customized
UserKnownHostsFile in /etc/ssh/ssh_config. This patch simply attempts to copy
those files too while going through /etc/ssh/ssh_config. Note that we need to
make sure ~/foo will be copied as /root/foo in kdump's initramfs.
