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. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1439562 Title: backport request: include support for OpenPower hardware Status in linux package in Ubuntu: Fix Released Status in linux source package in Utopic: New Status in linux source package in Vivid: Fix Released Bug description: [Impact] This is a HWE SRU for OpenPower support in 3.16.

The changes are available in the ubuntu/vivid branch of: https://github.com/open-power/linux.git (or I can attach them separately). Changelogs are as follows: commit 2f0190bd43764559b250a5bd11aca050f909aa21 Author: Benjamin Herrenschmidt <b...@kernel.crashing.org> Date: Fri Nov 14 16:13:50 2014 +1100 powerpc/powernv: Support OPAL requested heartbeat If OPAL requests it, call it back via opal_poll_events() at a regular interval.

Basically, it boils down to correlating the sysfs device with the OF tree device node, so that user space can use device-tree info such as additional "location" or "label" (or whatever else we can come up with) propreties to identify a given device, or get some attributes of use about it, etc... Now, so far, we've done that in some subsystem in a fairly ad-hoc basis using "devspec" properties. For example, PCI creates them if it can correlate the probed device with a DT node. Some powerpc specific busses do that too. However, i2c doesn't and it would be nice to have something more generic since technically any device can have a corresponding device tree node. This patch adds an "of_node" symlink to devices that have a non-NULL dev->of_node pointer, the patch is pretty trivial and seems to work just fine for me.

This is syscall number 0x1ebe, which is handled explicitly in the 64-bit syscall exception entry. That has a few problems, firstly the syscall number is outside of the usual range, which confuses various tools. For example strace doesn't recognise the syscall at all. Secondly it's handled explicitly as a special case in the syscall exception entry, which is complicated enough without it. As a first step toward removing the special syscall, we need to add a regular syscall that implements the same functionality. The logic is simple, it simply toggles the MSR_LE bit in the userspace MSR. This is the same as the special syscall, with the caveat that the special syscall clobbers fewer registers. This version clobbers r9-r12, XER, CTR, and CR0-1,5-7.

We register platform devices for the flash devices exported by firmware. We clash with the existing opal_flash_init function, which is really for the FSP flash update functionality, so we rename that initcall to opal_flash_update_init(). A future change will add an mtd driver that uses this interface. Changes from Joel Stanley and Jeremy Kerr.

This adds orderly_reboot that will cause userspace to shut itself down by calling /sbin/reboot. This will be used for shutdown initiated by a system controller on platforms that do not use ACPI. orderly_reboot() should be used when the system wants to allow userspace to gracefully shut itself down. For cases where the system may imminently catch on fire, the existing emergency_restart() provides an immediate reboot without involving userspace.
