Here is what I get.
Current git HEAD is: 0c14e43a42e4e44f70963f8ccf89461290c4e4da if I do:

$ git revert 373e098e1e788d7b89ec0f31765a6c08e2ea0f7c

* [PATCH V3 2/2] crypto/nx: Initialize 842 high and normal RxFIFO control registers
From: Haren Myneni @ 2018-06-13 7:32 UTC (permalink / raw)
To: mpe; +Cc: herbert, stewart, linux-crypto, linuxppc-dev
NX increments readOffset by FIFO size in receive FIFO control register
when CRB is read. But the index in RxFIFO has to match with the
corresponding entry in FIFO maintained by VAS in kernel. Otherwise NX
may be processing incorrect CRBs and can cause CRB timeout.
VAS FIFO offset is 0 when the receive window is opened during
initialization. When the module is reloaded or in kexec boot, readOffset
in FIFO control register may not match with VAS entry. This patch adds
nx_coproc_init OPAL call to reset readOffset and queued entries in FIFO
control register for both high and normal FIFOs.

If we successfull call ->probe twice on a device we have a much
deeper problem than we can fix in the PCI layer or shpchp.
Please explain the actual race or other condition that can lead to

* [patchV2 2/2] pci/shpchp: no claim on pcie port device
From: Pingfan Liu @ 2018-06-13 6:29 UTC (permalink / raw)
To: linux-pci; +Cc: Bjorn Helgaas, Christoph Hellwig, linuxppc-dev
In-Reply-To: <1528871397-17917-1-git-send-email-kernelfans@gmail.com>
The Linux Device Driver Model allows a physical device to be handled
by only a single driver. But at present, both shpchp and portdrv_pci
claim PCI_CLASS_BRIDGE_PCI, and touch devices_kset when the drivers are
loaded. This causes a few problems, one is the wrong shutdown seq of
devices, owing to the broken devices_kset. This patch keeps shpchp away
from pcie port device, using the extra matching method.
Note:
I hit this bug on a Power9 machine, when "kexec -e", and see a ata-disk
behind a bridge can not write back buffer in flight due to the former
shutdown of the bridge which clears the BusMaster bit.

* [patchV2 1/2] pci: introduce an extra method for matching in pci_driver
From: Pingfan Liu @ 2018-06-13 6:29 UTC (permalink / raw)
To: linux-pci; +Cc: Bjorn Helgaas, Christoph Hellwig, linuxppc-dev
In-Reply-To: <1528871397-17917-1-git-send-email-kernelfans@gmail.com>
In __driver_attach(), if a driver matches a device, the device will
be appended to the tail of devices_kset, no matter what the probing
result of the device. Hence in order to prevent a driver to append
a probed device to devices_kset, it requires a correct matching.
As for pci, pci driver uses pci_device_id to match a device. But it may
be not enough, since there is need for extra info such as pcie, which
can not be provided in pci_device_id. Such info is driver specific, and
this patch introduces a new method "extra_match" in pci_driver.
This is used by next patch.

* [patchV2 0/2] shpchp: no claim on pcie port device
From: Pingfan Liu @ 2018-06-13 6:29 UTC (permalink / raw)
To: linux-pci; +Cc: Bjorn Helgaas, Christoph Hellwig, linuxppc-dev
The Linux Device Driver Model allows a physical device to be handled
by only a single driver. But at present, both shpchp and portdrv_pci
claim PCI_CLASS_BRIDGE_PCI. This cause problems, such as the wrong
shutdown seq. This series keeps shpchp driver away from pcie port device.
V1 -> V2:
implement the checking in the process of matching, instead of probing,
which is too late.

* [RFC PATCH] powerpc/64s/radix: Fix MADV_[FREE|DONTNEED] TLB flush miss problem with THP
From: Nicholas Piggin @ 2018-06-13 6:05 UTC (permalink / raw)
To: linuxppc-dev; +Cc: Nicholas Piggin, Aneesh Kumar K . V
The patch 99baac21e4 ("mm: fix MADV_[FREE|DONTNEED] TLB flush miss
problem") added a force flush mode to the mmu_gather flush, which
unconditionally flushes the entire address range being invalidated
(even if actual ptes only covered a smaller range), to solve a problem
with concurrent threads invalidating the same PTEs causing them to
miss TLBs that need flushing.
This does not work with powerpc that invalidates mmu_gather batches
according to page size. Have powerpc flush all possible page sizes in
the range if it encounters the concurrency condition.
[ Do we need to do anything for hash? ]

This says that I can use "nmi_watchdog=hpet" without using 0 or 1.
Is that correct?

I thought we had a test case for this, and it seems that we did, but it
never made it into mainline.
Anshuman wrote it originally but then passed it onto Simon who
resubmitted it and I merged it, but then I must have reverted the EBB
test because it was failing, see:
http://patchwork.ozlabs.org/patch/676833/
So it would be good to get that test case working reliably. I'm not sure
if would have found this bug anyway, but it would be a start.

I don't think so.
Imagine we take a multi-hit accessing the paca. The machine check is
delivered in real mode, so we can run and access the paca by it's real
address. But as soon as we turn the MMU back on, we'll take another
multi-hit when we access the paca.
If I'm reading the code right we are turning the MMU back on essentially
straight away when we rfid to machine_check_common().

Yeah for duplicate entries for kernel segment "0xc00", we will end up
with another multi-hit. For other segments we won't. I think I need to
move the fetching of rtas error log and handling part into real mode to
avoid a loop, and do only printing part in virtual mode.

slb_flush_and_rebolt does slbia, which keeps slb index 0. So kernel code
should not get another slb miss. We also make sure we don't touch stack
in slb_flush_and_rebolt(). So we flush everything and put vmalloc and
stack back. That should be ok with MMU on?

I think we already have 8 (!) copies of this logic in ptrace.c.
And you add two more, seems like it should be in a helper function.
Can you add a helper that does it and use that helper in these two
functions. Then if you can send me another patch that converts all the
other uses to use the new helper.

Hi Pedro,
Thanks for looking into this, how did you detect this? Do you have a
test case?
I don't think Anshuman wrote it this way on purpose, but added him to Cc
in case he remembers.
But I don't think this fix is necessarily right. If we are setting the
EBB regs via ptrace then it doesn't matter if they were previously in
use or not, we should just set them. What *does* matter is that at the
end of the function we set used_ebb to true, because otherwise the
values we have set will not actually be used when the process is
rescheduled.

It looks like a real overflow, I guess the question is why are we seeing it.
The first thing to work out would be what exactly is overflowing.
Is it in here?
cfqg_stats_update_completion(cfqq->cfqg, rq->start_time_ns,
rq->io_start_time_ns, rq->cmd_flags);
If so that would suggest something is taking multiple hours to complete,
which seems unlikely. Is time going backward?

Confirmed. The SDK says
"INVLPG also invalidates all entries in all paging-structure caches
associated with the current PCID, regardless of the linear addresses
to which they correspond"
so if x86 wants to do this "separate invalidation for page directory
entryes", then it would want to
(a) remove the __tlb_adjust_range() operation entirely from
pud_free_tlb() and friends
(b) instead just have a single field for "invalidate_tlb_caches",
which could be a boolean, or could just be one of the addresses
and then the logic would be that IFF no other tlb invalidate is done
due to an actual page range, then we look at that
invalidate_tlb_caches field, and do a single INVLPG instead.
I still am not sure if this would actually make a difference in
practice, but I guess it does mean that x86 could at least participate
in some kind of scheme where we have architecture-specific actions for
those page directory entries.
And we could make the default behavior - if no architecture-specific
tlb page directory invalidation function exists - be the current
"__tlb_adjust_range()" case. So the default would be to not change
behavior, and architectures could opt in to something like this.

Keep the HPET-based hardlockup detector disabled unless explicitly enabled
via a command line argument. If such parameter is not given, the hardlockup
detector will fallback to use the perf-based implementation.
The function hardlockup_panic_setup() is updated to return 0 in order to
to allow __setup functions of specific hardlockup detectors (in this case
hardlockup_detector_hpet_setup()) to inspect the nmi_watchdog boot
parameter.
