We met a problem that the kdump emergency service failed to
start when the target dump timeout(we passed "rd.timeout=30"
to kdump), it reported "Transaction is destructive" messages:

[FAILED] Failed to start Kdump Emergency.
See 'systemctl status emergency.service' for details.
[DEPEND] Dependency failed for Emergency Mode.
This is because in case of root failure, initrd-root-fs.target
will trigger systemd emergency target which requires the systemd
emergency service actually is kdump-emergency.service, then our
kdump-emergency.service starts kdump-error-handler.service with
"systemctl isolate"(see 99kdumpbase/kdump-emergency.service, we
replace systemd's with this one under kdump).
This will lead to systemd two contradictable jobs queued as an
atomic transaction:
job 1) the emergency service gets started by initrd-root-fs.target
job 2) the emergency service gets stopped due to "systemctl isolate"
thereby throwing "Transaction is destructive".
In order to solve it, we can utilize "IgnoreOnIsolate=yes" for both
kdump-emergency.service and kdump-emergency.target. Unit with attribute
"IgnoreOnIsolate=yes" won't be stopped when isolating another unit,
they can keep going as expected in case be triggered by any failure.
We add kdump-emergency.target dedicated to kdump the similar way
as did for kdump-emergency.service(i.e. will replace systemd's
emergency.target with kdump-emergency.target under kdump), and
adds "IgnoreOnIsolate=yes" into both of them.

Patches have been taken from kexec-tools and makedumpfile to fix issue
with `makedumpfile --mem-usage /proc/kcore`.
Two of the patches is from kexec-tools and rest are from makedumpfile.
All the patches have been acked upstream and applies without conflict.
Kexec-tools patches:
(kexec-tools-2.0.14-x86-x86_64-Fix-format-warning-with-die.patch), which
fixes koji build issue.
kexec-tools-2.0.14-build_mem_phdrs-check-if-p_paddr-is-invalid.patch fixes
the regresssion caused by kernel /proc/kcore fix to use -1 as default value
of p_paddr for pt_loads. Without his patch kexec -p will fail with latest
kernel.
Other makedumpfile patches are backported to support --mem-usage while
kernel kaslr being enabled. Details please see the patch log of the individual
patches.
All the patches are backport of upstream commits.
Patches has been tested with kernel 4.11.0-0.rc1.git0.1.fc26.x86_64.

kexec/arch/i386: Add support for KASLR memory randomization
Multiple changes were made on KASLR (right now in linux-next). One of
them is randomizing the virtual address of the physical mapping, vmalloc
and vmemmap memory sections. It breaks kdump ability to read physical
memory.
This change identifies if KASLR memories randomization is used by
checking if the page_offset_base variable exists. It search for the
correct PAGE_OFFSET value by looking at the loaded memory section and
find the lowest aligned on PUD (the randomization level).

Fix Bug 925630 - kexec-tools: support for arm64
https://bugzilla.redhat.com/show_bug.cgi?id=925630
involves three things:
1. back porting upstream code to enable the function of kexec-tools on arm64
patchset backported from upstream:
commit abdfe97736f89d9bc73662b9134604b0229a599e
commit 522df5f7217fda01ece3f6ac3e9987b0320c2bb0
commit 217bcc00c9309416a6c6cd0584196559d28a9259
2. fix the arm related building issue by using autoreconf in spec file
3. patches to fix the issue of higher version gcc used by koji (not upstrem yet,
and the corresponding fix in kernel side is in other package)

Since in Fedora 25 kernel kaslr is enabled (x86) but makedumpfile can not save
a correct vmcore, so it means kdump default setup will not work.
Pratyush posted a patch series to upstream which can fix the issue. Let's merge them in F25, will get the normal fixes after it being merged in upstream, we hopefully can rebase soon in rawhide.
This is an urgent fix for F25 since F25 freeze is this week.

Moving isys.total_memory() call to class method to avoid installation hangs.
It is possible because totoal_memory will call log.info which need log lock.
but some loging function need import gettext module which need import lock.
Thus deadlock could happen.
Moved isys.total_memory callback to class method instead.
Updated kdump addon icon again, Máirín Duffy designed a better icon,
it shows a little blip in a heart beat with a magnifying class examining
it, it uses components of the gnome-symbolic-theme so it would match the
