ea5c605d16 blacklist patch apply fix
The original blacklist patch was applied without conflict.
But in fact there's exactly same context with amerigo's original patch and
it's in wrong place!

Moving it to the right switch branch..

1b30666cac add blacklist option
For the "blacklist" here, it means prevent the kernel modules
from loading into kdump initrd, which is different from RHEL6.

7a7ecb150b omit plymouth module
Resolves: bz821997

while root is set to dump target, it can not be unmounted because plymouthd
are holding it. umount failing will cause calling of default_action.

Omit plymouth module to fix this issue.
Also drop "--add dash" or dracut will report error "dash is not found", this
is because default fedora dracut.conf will omit dash.

015dd4c67c mkdumprd: Start using --hostonly and --add kdumpbase while calling dracut
BZ: 817044

Harald suggested that we use --add kdumpbase instead of -m kdumpbsae. As
-m means only use modules specified on the command line. I am not sure
that kdump will ever know the list of modules it wants to use. It might
be a good idea to let dracut decide it based on --mount option.

Also start using --hostonly to make sure atleast our default dumping to
root disk always works.

I also noticed that with --add and --hostonly initramfs size came down. So
for the time being just bring down the initramfs size.

But it still looks big and this area will require more experimentation and
bug fixing to make sure we are generatiing optimal size images for kdump
purposes and get rid of bloat. I am just beginning to understand dracut,
so expect more churn in this area down the line from me.

I am posting this patch for the bz opened again F18. As it is reducing
initramfs size significantly, I think it is a good idea to commit it
in F17 branch also.

Following is image size comparision.

Dump to root disk.
------------------
vanilla compressed: 13MB
hostonly compressed: 7.5MB

Dump to nfs
-----------
vanilla compressed: 24MB
hostonly compressed: 13MB

Dump over ssh
-------------
vanilla compressed: 23.5 MB
hostonly compressed: 12 MB

24eaa7da8f port raw dump from rhel6 [v7]
Resolves: bz805783

kdumpctl: save_raw if found vmcore
mkdumprd: checking available size of raw disk
dracut module: do the dumping

Note, add a dir /kdumpscripts for monitor_dd_progress and future
kdump scripts
[v1->v2]: monitor_dd_process become a script instead of a function
          add missed utils
          use pipe with dc
[v2->v3]: Don: fix dd_progress_file typo
          Vivek: move [ -f $conf_file ] earlier
                 don't split keyfile= and [ -f keyfile ]
                 move default core_collector earlier
                 move non-makedumpfile warnings to mkdumprd
                 make check available size a common function
          Amerigo: use less pipe for grep then awk print
                   use shell (( )) instead of dc
          use cut instead of awk
          no need install dc and awk
          make DD_BLKSIZE a variable
          don't add 0755 file in git, chmod in module-setup.sh
[v3->v4]: vivek: kdumpctl multi raw target handling
          monitor_dd_progress- fix wrong size calculation:
          the tail -1 of dd pregress file is in bytes instead of blocks
          only print the whole dd src file size for non-filtered case
          check [ -b raw target device ] before dump
[v4->v5]: vivek: move check [ -b $1 ] before monitor_dd_progress
          remove multi target function
[v5->v6]: vivek: only warning for raw dump of non-makedumpfile core_collector
[v6->v7]: kdumpctl should return 0 when there's no raw target

ba0aa24316 Add ssh dump support
Add ssh dump support

changes including below items:
1. sshkey option
2. sshkey propagate
3. fix a bug of  _server ip calculation for dump target string
4. change the prefix of kdump hook from 93 to 01 to avoid dhclient and
   other cleanups happening before us
5. enable network with dracut cmdline rd.neednet=1 when there's network
   target config

[v1 - v2]:
Only check_ssh_target when there's ssh dump target in kdump config file

[v2 -> v3]
style fixes: trailing spaces and space before tab indent
remove set -x
simply check_ssh_target
use awk to get sshkey option value
change pivot hook order to 0000
