Hello Canonical,

All the patches are accepted in upstream.. Please pull below three
patches..

[We have launchpad bug #1491063 for 15.04 series.]

commit 546174be41c74894126414515644888ed8b31584
Author: Vasant Hegde <hegdevasant at linux.vnet.ibm.com>
Date:   Wed Sep 2 10:23:21 2015 -0400

update_flash: Fix bad variable issue
Shells like dash throws error if we try to assign string with space
without double quote. ex:
local bug=ML FW830.00 FW830.00
Sample output without this patch:
update_flash -f 01SV840_016_016.img
/usr/sbin/update_flash: 185: local: FW830.00: bad variable name

commit 62dc6d38de177588f205e01cec15b93b3e2b9a30

update_flash: Stop kexec service before starting firmware update
We run 'reboot' call before initiating firmware update. If kexec service
is enabled, then we endup booting into new kernel instead of starting
firmware update.
This patch validates kexec service and if required stops this service
before starting code update.

commit 8ff5144da07985cd84508465007f9031840d4ecd

update_flash: Stop kexec service before starting firmware update on PowerVM LPAR
We run 'reboot' call before initiating firmware update. If kexec service
is enabled, then we endup booting into new kernel instead of starting
firmware update.
Commit 62dc6d38 fix this issue on PowerNV platform.. but missed to fix
PowerVM LPAR.  This patch fixes above described issue on PowerVM LPAR.

  Userspace tool common name: /usr/sbin/update_flash 
   
  The userspace tool has the following bit modes: 64-bit 

  Workaround:

  In the mean time, you can stop kdump service and do the FW update..
  That should work ..
