Currently in the whole kdump framework, we have some common functions
used across not only mkdumprd context and dracut context, but also 1st
kernel and 2nd kernel. We defined these functions at each script, which
is obviously not decent.
So let's introduce kdump-lib.sh for the shared functions and put it
to /lib/kdump/kdump-lib.sh.
It starts small, as you can see, only 3 functions are extracted. But in
the future more and more common functions can be added.

Build on ppc/ppc64 failed after makedumpfile-1.5.4 is pulled, since the
variable vmap_area_list is not defined. Back port below commit from
upstream to add it.

[PATCH] Add vmap_area_list definition for ppc/ppc64.
vmap_area_list is added to get vmalloc_start for ppc/ppc64, but its
definition is missing, now add them.

Percent signs in .spec files get expanded as macros. Currently in kexec-tools.spec,
'%{dist}' are appended to changelog item. This older changelog is not correctly for
rhel7 with this. Let's remove it to make it clearer.
Fedora 18 changes the way how to work with services in spec files.
It introduces new macros - %systemd_post, %systemd_preun and
%systemd_postun. These macros are functionally equivalent to the
manual scriptlets used in older versions of Fedora.
By using the new unified RPM macros the .spec file code is
simplified a lot.

Currenty the kexec-tools package contains udev rules for kdump
that reload kdump in case of memory or CPU hotplug:
$ cat /etc/udev/rules.d/98-kexec.rules
SUBSYSTESUBSYSTEM=="cpu", ACTION=="online", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="cpu", ACTION=="offline", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="memory", ACTION=="add", PROGRAM="/bin/systemctl try-restart kdump.service"
SUBSYSTEM=="memory", ACTION=="remove", PROGRAM="/bin/systemctl try-restart kdump.service"
On other architectures the rules are necessary because the memory
and CPU layout stored in the kdump in-memory ELF header at kdump
load time. Therefore the kdump kernel has to be reloaded each
time when the CPU or memory configuration changes.
This has drawbacks:
1. During kdump reload the system can't be dumped.
2. On systems with many hotplug events (e.g. on s390 with cpuplugd)
this creates significant overhead
The reload is not necessary on s390 because there the ELF header is
created in the 2nd (kdump) kernel. Therefore, to improve things,
remove the rules for s390.
Log is from IBM, and patch has been tested by IBM and work well.

Below patches were applied to kexec-tools-2.0.3, the latest
kexec-tools-2.0.4 has included them. Delete them here.

Because makedumpfile is not supported on ppc and s390, so it makes
no sense to create the eppic_makedumpfile sub-package if there is
no makedumpfile binary to run it with.
Remove eppic contents related to ppc and s390 in kexec-tools.spec. This
will not build and install eppic on ppc and s390.
There's one mistake in rules related to eppic in kexec-tools.spec,
that caused kexec-tools-eppic to fail installation of i386. In this
patch remove that line of rule.
Meanwhile update eppic_030413.tar.gz.
This feature enables us to specify rules to scrub data in a
dumpfile with eppic macro instead of the current configuration
file (makedumpfile.conf). Currently, this feature works only
for symbols in vmlinux while the current feature can work also
for module symbols.
This library is backported from upstream, integrated and tested by
Dave Anderson.
This reverts commit 05b67ee95c.
The old commit was merged for a emergent bug fixing on release 1.5.1
of makedumpfile. Now the upstream has been updated to v1.5.3, and this
patch has been included already.
For updating to makedumpfile v1.5.3, revert it.

Current kdump image name prefix has changed from initrd to initramfs.
