parisc: %pf is only for function pointers
Use %ps for actual addresses, otherwise you'll get bad output
on arches like parisc64 where %pf expects a function descriptor.
This wasn't normally seen on parisc64 because the code is not built
unless DEBUG_SUPERIO_INIT is manually defined.
Patch modified by Helge Deller to utilize KERN_DEBUG.

Pull MTD updates from Brian Norris:
"Common MTD:
- Add Kconfig option for keeping both the 'master' and 'partition'
MTDs registered as devices. This would really make a better
default if we could do it over, as it allows a lot more flexibility
in (1) determining the flash topology of the system from user-space
and (2) adding temporary partitions at runtime (ioctl(BLKPG)).
Unfortunately, this would possibly cause user-space breakage, as it
will cause renumbering of the /dev/mtdX devices. We'll see if we
can change this in the future, as there have already been a few
people looking for this feature, and I know others have just been
working around our current limitations instead of fixing them this
way.
- Along with the previous change, add some additional information to
sysfs, so user-space can read the offset of each partition within
its master device
SPI NOR:
- add new device tree compatible binding to represent the
mostly-compatible class of SPI NOR flash which can be detected by
their extended JEDEC ID bytes, cutting down the duplication of our
ID tables
- misc. new IDs

crush: straw2 bucket type with an efficient 64-bit crush_ln()
This is an improved straw bucket that correctly avoids any data movement
between items A and B when neither A nor B's weights are changed. Said
differently, if we adjust the weight of item C (including adding it anew
or removing it completely), we will only see inputs move to or from C,
never between other items in the bucket.
Notably, there is not intermediate scaling factor that needs to be
calculated. The mapping function is a simple function of the item weights.
The below commits were squashed together into this one (mostly to avoid
adding and then yanking a ~6000 lines worth of crush_ln_table):
- crush: add a straw2 bucket type
- crush: add crush_ln to calculate nature log efficently
- crush: improve straw2 adjustment slightly
- crush: change crush_ln to provide 32 more digits
- crush: fix crush_get_bucket_item_weight and bucket destroy for straw2
- crush/mapper: fix divide-by-0 in straw2

to create a proper compat.h in ceph.git)

ia64/PCI: Treat all host bridge Address Space Descriptors (even consumers) as windows
Prior to
c770cb4cb505 ("PCI: Mark invalid BARs as unassigned"), if we tried
to claim a PCI BAR but could not find an upstream bridge window that
matched it, we complained but still allowed the device to be enabled.
c770cb4cb505 broke devices that previously worked (mptsas and igb in the
case Tony reported, but it could be any devices) because it marks those
BARs as IORESOURCE_UNSET, which makes pci_enable_device() complain and
return failure:
igb 0000:81:00.0: can't enable device: BAR 0 [mem size 0x00020000] not assigned
igb: probe of 0000:81:00.0 failed with error -22
The underlying cause is an ACPI Address Space Descriptor for a PCI host
bridge window that is marked as "consumer". This is a firmware defect:
resources that are produced on the downstream side of a bridge should be
marked "producer". But rejecting these BARs that we previously allowed is
a functionality regression, and firmware has not used the producer/consumer
bit consistently, so we can't rely on it anyway.
Stop checking the producer/consumer bit, and assume all bridge Address
Space Descriptors are for bridge windows.
Note that this change does not affect I/O Port or Fixed Location I/O Port
Descriptors, which are commonly used for the [io 0x0cf8-0x0cff] config
access range. That range is a "consumer" range and should not be treated
as a window.

Revert "ocfs2: incorrect check for debugfs returns"
This reverts commit
e2ac55b6a8e337fac7cc59c6f452caac92ab5ee6.
Huang Ying reports that this causes a hang at boot with debugfs disabled.
It is true that the debugfs error checks are kind of confusing, and this
code certainly merits more cleanup and thinking about it, but there's
something wrong with the trivial "check not just for NULL, but for error
pointers too" patch.
Yes, with debugfs disabled, we will end up setting the o2hb_debug_dir
pointer variable to an error pointer (-ENODEV), and then continue as if
everything was fine. But since debugfs is disabled, all the _users_ of
that pointer end up being compiled away, so even though the pointer can
not be dereferenced, that's still fine.
So it's confusing and somewhat questionable, but the "more correct"
error checks end up causing more trouble than they fix.

The Error-Bit on the avalon streaming interface of the

this leads to error-symbols on the PCS and packet-rejection

This only applies to the tse-configuration with MSGDMA.
This issue was detected and fixed on a custom board with
a direct connection to a Marvell switch in SGMII-PHY-Mode.
(incl. custom patches for SGMII-PCS).
According to the datasheet if ff_tx_err (avalon-streaming)

Merge branch 'ppp_csum_unset'
Tom Herbert says:
====================
net: Fix "hw csum failure" message flood for ppp tunnel
This patch set addresses bug "Bug 95171 - "hw csum failure" message
flood for ppp tunnel since upgrade to 3.16". The problem is that pppoe
is being used over UDP with UDP checksusm enabled. On receive
checksum conversion turns checksum-unnecessary in checksum-
complete. The PPP receive functions do not properly pull
the checksum over its headers, so that when an encapsulated
checksums is considered the checksum-complete value is incorrect.
This patch adds skb_checksum_complete_unset which can be called
in the receive path in lieu of pulling checksum complete in
layer. This is useful when the packet is being modified (e.g.
decompressed) and the checksum-complete value is no longer
relevant.
In the ppp_receive_frame we call skb_checksum_complete_unset to toss
out checksum-complete. This should eliminate the reported messages.
Alternatively, we could add skb_postpull_rcsum and probably
special case handling for VJ compression if maintaining the
checksum-complete is needed (not clear to me this is worth the
effort).
I haven't tested this since setting up the failure scenario doesn't
seem trivial to configure.

Forwarded frames should not have a socket attached. Especially
tw sockets will lead to panics later-on in the stack.
This was observed with TPROXY assigning a tw socket and broken
policy routing (misconfigured). As a result frame enters
forwarding path instead of input. We cannot solve this in

smp: don't use 16-bit words for atomic accesses
Yes, it should work, but it's a bad idea. Not only did ARM64 not have
the 16-bit access code (there's a separate patch to add it), it's just
not a good atomic type. Some architectures fundamentally don't do
atomic accesses in them (alpha), and it's not like it saves any space
here anyway because of structure packing issues.
We normally should aim for flags to be "unsigned int" or "unsigned
long". And if space is at a premium, use a single byte (although that
causes problems on alpha again). There might be very special cases
where a 16-byte entity is really wanted, but this is not one of them.
