I don't have that commit ^ ?
That might be because I squashed some of your fixes together or something?

I have:
#ifdef CONFIG_PPC32
void setup_power_save(void);
#else
static inline void setup_power_save(void) { };
#endif

Greeting's
WARN_ONCE is triggered when interface is toggled when running 'ethtool -S' command
on a powerpc machine running today's mainline kernel
related commit looks to be:
commit 9b10df596bd4d38f2a58cf87e0780510acc53d8d
Author: Jacob Keller <jacob.e.keller@intel.com>
Date: Thu May 17 01:08:36 2018 -0700
i40e: use WARN_ONCE to replace the commented BUG_ON size check
We don't really want to use BUG_ON here since that would completely
crash the kernel, thus the reason we commented it out. We *can't* use
BUILD_BUG_ON because at least now (a) the sizes aren't constant (we are
fixing this) and (b) not all compilers are smart enough to understand
that "p - data" is a constant.
Machine: Power 8 bare-metal

Yeah OK. We don't have a good way to express that, other than using a
merge which I'd prefer to avoid.
So I've tagged them all with your Tested-by. If any of them turn out to
have bugs you can blame me :)

* [PATCH kernel v2 REPOST] powerpc/powernv/ioda: Allocate indirect TCE levels on demand
From: Alexey Kardashevskiy @ 2018-06-21 9:36 UTC (permalink / raw)
To: linuxppc-dev
Cc: Alexey Kardashevskiy, David Gibson, kvm-ppc, Alex Williamson,
Benjamin Herrenschmidt, Russell Currey
In-Reply-To: <20180621020321.GE32328@umbus.fritz.box>
At the moment we allocate the entire TCE table, twice (hardware part and
userspace translation cache). This normally works as we normally have
contigous memory and the guest will map entire RAM for 64bit DMA.
However if we have sparse RAM (one example is a memory device), then
we will allocate TCEs which will never be used as the guest only maps
actual memory for DMA. If it is a single level TCE table, there is nothing
we can really do but if it a multilevel table, we can skip allocating
TCEs we know we won't need.
This adds ability to allocate only first level, saving memory.
This changes iommu_table::free() to avoid allocating of an extra level;
iommu_table::set() will do this when needed.
This adds @alloc parameter to iommu_table::exchange() to tell the callback
if it can allocate an extra level; the flag is set to "false" for
the realmode KVM handlers of H_PUT_TCE hcalls and the callback returns
H_TOO_HARD.
This still requires the entire table to be counted in mm::locked_vm.
To be conservative, this only does on-demand allocation when
the usespace cache table is requested which is the case of VFIO.
The example math for a system replicating a powernv setup with NVLink2
in a guest:
16GB RAM mapped at 0x0
128GB GPU RAM window (16GB of actual RAM) mapped at 0x244000000000
the table to cover that all with 64K pages takes:
(((0x244000000000 + 0x2000000000) >> 16)*8)>>20 = 4556MB
If we allocate only necessary TCE levels, we will only need:
(((0x400000000 + 0x400000000) >> 16)*8)>>20 = 4MB (plus some for indirect
levels).

This is what I meant to post few days ago, sorry for the noise.
---
Changes:
v2:
* fixed bug in cleanup path which forced the entire table to be
allocated right before destroying
* added memory allocation error handling pnv_tce()

* [PATCH 1/2] powerpc/mm: Check memblock_add against MAX_PHYSMEM_BITS range
From: Aneesh Kumar K.V @ 2018-06-21 8:31 UTC (permalink / raw)
To: npiggin, benh, paulus, mpe; +Cc: linuxppc-dev, Aneesh Kumar K.V
With SPARSEMEM config enabled, we make sure that we don't add sections beyond
MAX_PHYSMEM_BITS range. This results in not building vmemmap mapping for
range beyond max range. But our memblock layer looks the device tree and create
mapping for the full memory range. Prevent this by checking against
MAX_PHSYSMEM_BITS when doing memblock_add.
We don't do similar check for memeblock_reserve_range. If reserve range is beyond
MAX_PHYSMEM_BITS we expect that to be configured with 'nomap'. Any other
reserved range should come from existing memblock ranges which we already
filtered while adding.
This avoids crash as below when running on a system with system ram config above

OK.
Though prior to patch 6 all threads have read/write permissions for all
keys, so they don't necessarily need to change permissions on a key
allocated by another thread.

Multi-threaded applications were able to use the API, as long as they
were satisfied with the semantics it provided, ie. that restrictions on
a key were only possible on the thread that allocated the key.
I'm not trying to argue for the sake of it, it's important that we
understand the subtleties of what we're changing and how it affects
existing software - even if we think there is essentially no existing
software.
I'll try and massage the change log to capture it.
I ended up with what's below.
cheers
powerpc/pkeys: Give all threads control of their key permissions
Currently in a multithreaded application, a key allocated by one
thread is not usable by other threads. By "not usable" we mean that
other threads are unable to change the access permissions for that
key for themselves.
When a new key is allocated in one thread, the corresponding UAMOR
bits for that thread get enabled, however the UAMOR bits for that key
for all other threads remain disabled.
Other threads have no way to set permissions on the key, and the
current default permissions are that read/write is enabled for all
keys, which means the key has no effect for other threads. Although
that may be the desired behaviour in some circumstances, having all
threads able to control their permissions for the key is more
flexible.
The current behaviour also differs from the x86 behaviour, which is
problematic for users.
To fix this, enable the UAMOR bits for all keys, at process
creation (in start_thread(), ie exec time). Since the contents of
UAMOR are inherited at fork, all threads are capable of modifying the
permissions on any key.
This is technically an ABI break on powerpc, but pkey support is
fairly new on powerpc and not widely used, and this brings us into
line with x86.

Well threads is one thing, but this also affects processes.
And actually without this fix it's possible that a child process could
fault on a region protected in the parent, if the value in the AMR in
the thread struct happens to block access at the time of fork(). The
value in the thread struct would be whatever was in the AMR the last
time the parent was scheduled in. I think?

"likely" makes me nervous. Is there a case were it might not be real

Has idx already been bounds checked at this point? If not, couldn't
you get here due to an out of bounds index, in which case it wouldn't
be H_HARDWARE, but H_PARAMETER or something.

this cannot be unsigned, since it can get set to -1 if key 2 is not available. :(

OK done.
See eg:
http://kisskb.ellerman.id.au/kisskb/head/14180/
At the moment the "head" page shows the progress/successful for that
head across all branches, so the linus-rand results get counted together
with the linus results which is a bit annoying.
I'm working on a change so that you can view a head *on a branch* so
that you only see the progress/successful for that branch. I'll try and
polish that up and get it pushed RSN.

I think the numbering change has to be coped with. However:
The main issue I see is that it somewhat hard wires that "reg"
is a 64-bit property with the "interesting" bits in the bottom,
and that "interesting" part somewhat happens to fit in 16-bits.
It would have been better to get the full address out of reg (using the
appropriate size specified in the parent #address-cells) and hash it.

* [PATCH 2/3] migration/memory: Evaluate LMB assoc changes
From: Michael Bringmann @ 2018-06-21 0:34 UTC (permalink / raw)
To: linuxppc-dev
Cc: Michael Bringmann, Nathan Fontenot, John Allen, Tyrel Datwyler,
Thomas Falcon
In-Reply-To: <c7b0c1e5-7adf-299b-646f-6988b1fa0f8b@linux.vnet.ibm.com>
migration/memory: This patch adds code that recognizes changes to
the associativity of memory blocks described by the device-tree
properties in order to drive equivalent 'hotplug' operations to
update local and general kernel data structures to reflect those
changes. These differences may include:
* Evaluating 'ibm,dynamic-memory' properties when processing the
topology of LPARS in Post Migration events. Previous efforts
only recognized whether a memory block's assignment had changed
in the property. Changes here include checking the aa_index
values for each drc_index of the old/new LMBs and to 'readd'
any block for which the setting has changed.
* In an LPAR migration scenario, the "ibm,associativity-lookup-arrays"
property may change. In the event that a row of the array differs,
locate all assigned memory blocks with that 'aa_index' and 're-add'
them to the system memory block data structures. In the process of
the 're-add', the system routines will update the corresponding entry
for the memory in the LMB structures and any other relevant kernel
data structures.
A number of previous extensions made to the DRMEM code for scanning
device-tree properties and creating LMB arrays were used here to
ensure that the resulting code was simpler and more usable:
* Use new paired list iterator for the DRMEM LMB info arrays to find
differences in old and new versions of properties.
* Use new iterator for copies of the DRMEM info arrays to evaluate
completely new structures.
* Combine common code for parsing and evaluating memory description
properties based on the DRMEM LMB array model to greatly simplify
extension from the older property 'ibm,dynamic-memory' to the new
property model of 'ibm,dynamic-memory-v2'.

* [PATCH 1/3] powerpc/drmem: Export 'dynamic-memory' loader
From: Michael Bringmann @ 2018-06-21 0:34 UTC (permalink / raw)
To: linuxppc-dev
Cc: Michael Bringmann, Nathan Fontenot, John Allen, Tyrel Datwyler,
Thomas Falcon
In-Reply-To: <c7b0c1e5-7adf-299b-646f-6988b1fa0f8b@linux.vnet.ibm.com>
powerpc/drmem: Export many of the functions of DRMEM to parse
"ibm,dynamic-memory" and "ibm,dynamic-memory-v2" during hotplug
operations and for Post Migration events.
Also modify the DRMEM initialization code to allow it to,
* Be called after system initialization
* Provide a separate user copy of the LMB array that is produces
* Free the user copy upon request
In addition, a couple of changes were made to make the creation
of additional copies of the LMB array more useful including,
* Add new iterator to work through a pair of drmem_info arrays.
* Modify DRMEM code to replace usages of dt_root_addr_cells, and
dt_mem_next_cell, as these are only available at first boot.

* [PATCH 0/3] powerpc/migration: Affinity fix for memory
From: Michael Bringmann @ 2018-06-21 0:34 UTC (permalink / raw)
To: linuxppc-dev
Cc: Michael Bringmann, Nathan Fontenot, John Allen, Tyrel Datwyler,
Thomas Falcon
The migration of LPARs across Power systems affects many attributes
including that of the associativity of memory blocks. The patches
in this set execute when a system is coming up fresh upon a migration
target. They are intended to,
* Recognize changes to the associativity of memory recorded in
internal data structures when compared to the latest copies in
the device tree (e.g. ibm,dynamic-memory, ibm,dynamic-memory-v2).
* Recognize changes to the associativity mapping (e.g. ibm,
associativity-lookup-arrays), locate all assigned memory blocks
corresponding to each changed row, and readd all such blocks.
* Generate calls to other code layers to reset the data structures
related to associativity of memory.
* Re-register the 'changed' entities into the target system.
Re-registration of memory blocks mostly entails acting as if they
have been newly hot-added into the target system.
This code builds upon features introduced in a previous patch set
that updates CPUs for affinity changes that may occur during LPM.
