Jeremy,
Yea a new LP bug would make things easier to track, since we associate commits
with LP bug#s.
Thanks!

Jeremy,
The target was for Utopic (3.16), which didn't have the patch, no worries I'll
add it as well.
I'll put together a pull request for the list soon once I do a test build/boot.

Hi Chris,
Yes, 6a11e5c6 adds the IPMI driver. Is that not already in the vivid
tree?
The PRD and MTD changes are headed upstream, I was just sending to you
for an indication of what to expect.

Hi Chris,
Thanks for taking this on for a utopic backport.
Instead of using that ubuntu/utopic branch in the openpower tree, I'd
suggest using the upstream commits that we have listed in this bug (and
Tim has applied); that way, you'll be getting the latest changes, and
have less merging to do
Also are any CONFIG changes necessary? I see CONFIG_MTD_POWERNV_FLASH
was mentioned above, any thing additional for 3.16?

For 3.16, I'm assuming there are a lot of patchs here that may be needed:

Can you specify which are necessary?

* [Packaging] initscripts need installing when making the package
* [Packaging] initscripts work around bug in debhelper systemd support
[ Jay Vosburgh ]
Jeremy - thanks for the help. I've applied these patches:
powerpc/kernel: Make syscall_exit a local label
powerpc: Remove old compile time disabled syscall tracing code
powerpc: Add a proper syscall for switching endianness
powerpc/powernv: Remove opal prefix from pr_xxx()s
powerpc/powernv:
I applied these 4 patches. The rest will likely have to go through the
SRU process since kernel freeze is April 9.
Applying: powerpc/powernv: Add OPAL soft-poweroff routine
Applying: drivers/sbus/char/envctrl.c: ignore orderly_poweroff return value
Applying: kernel/reboot.c: add orderly_reboot
Jeremy - it looks like there is at least one missing prerequisite for
'powerpc: Add a proper syscall for switching endianness'. Can you
prepare a list of commits that apply to ubuntu-vivid ?

OK, we have a new set of patches merged. Would you like these in a
separate bug?
[the first does change a powerpc-specific syscall number, if that
affects your preference of SRU vs. freeze]
The following patches have been merged to linux-next:
1d9d9bd powerpc: Add a proper syscall for switching
Sure thing. The patch in my ubuntu-vivid git tree is slightly modified
from the upstream commit - just so we don't need to include those
prerequisites.
However, if you're after pristine upstream commits, the following will
work on top of the vivid tree (as at 83f803a6):
commit
Also, the 'powerpc/powernv: Support OPAL requested heartbeat' change
requires a couple of prereqs if you're looking to use the pristine
upstream version too:

This should do the trick:

Jeremy - I've just had a look at the patches you are proposing. Even
though this set only affects powernv, I would really prefer to cherry-

they appear to be HW related that ought to be OK since it is rare that
