These functions are not exported nor used anywhere, so there is no
reason to put them in public headers.
Also drop unused bcma_chipco_(suspend|resume).

It doesn't operate on PCI core, but PCI host device, so there is no
point of passing core related struct.

Bringing PCIe hosted bus up requires operating on host-related core.
Since we plan to support PCIe Gen 2 devices we should provide a helper
picking the correct one (PCIE or PCIE2).

Add two new ndo ops for IPv4 fib offload support, add and del. Add uses
modifiy semantics if fib entry already offloaded. Drivers implementing the new
ndo ops will return err<0 if programming device fails, for example if device's
tables are full.

This extends the design in commit 958501163ddd ("bridge: Add support for
IEEE 802.11 Proxy ARP") with optional set of rules that are needed to
meet the IEEE 802.11 and Hotspot 2.0 requirements for ProxyARP. The
previously added BR_PROXYARP behavior is left as-is and a new
BR_PROXYARP_WIFI alternative is added so that this behavior can be
configured from user space when required.
In addition, this enables proxyarp functionality for unicast ARP
requests for both BR_PROXYARP and BR_PROXYARP_WIFI since it is possible
to use unicast as well as broadcast for these frames.
The key differences in functionality:
BR_PROXYARP:
- uses the flag on the bridge port on which the request frame was
received to determine whether to reply
- block bridge port flooding completely on ports that enable proxy ARP
BR_PROXYARP_WIFI:
- uses the flag on the bridge port to which the target device of the
request belongs
- block bridge port flooding selectively based on whether the proxyarp
functionality replied

This change adds a new Kconfig option MPLS_ROUTING.
The core of this change is the code to look at an mpls packet received
from another machine. Look that packet up in a routing table and
forward the packet on.
Support of MPLS over ATM is not considered or attempted here. This
implemntation follows RFC3032 and implements the MPLS shim header that
can pass over essentially any network.
What RFC3021 refers to as the as the Incoming Label Map (ILM) I call
net->mpls.platform_label[]. What RFC3031 refers to as the Next Label
Hop Forwarding Entry (NHLFE) I call mpls_route. Though calling it the
label fordwarding information base (lfib) might also be valid.
Further the implemntation forwards packets as described in RFC3032.
There is no need and given the original motivation for MPLS a strong
discincentive to have a flexible label forwarding path. In essence
the logic is the topmost label is read, looked up, removed, and
replaced by 0 or more new lables and the sent out the specified
interface to it's next hop.
Quite a few optional features are not implemented here. Among them
are generation of ICMP errors when the TTL is exceeded or the packet
is larger than the next hop MTU (those conditions are detected and the
packets are dropped instead of generating an icmp error). The traffic
class field is always set to 0. The implementation focuses on IP over
MPLS and does not handle egress of other kinds of protocols.
Instead of implementing coordination with the neighbour table and
sorting out how to input next hops in a different address family (for
which there is value). I was lazy and implemented a next hop mac
address instead. The code is simpler and there are flavor of MPLS
such as MPLS-TP where neither an IPv4 nor an IPv6 next hop is
appropriate so a next hop by mac address would need to be implemented
at some point.
Two new definitions AF_MPLS and PF_MPLS are exposed to userspace.
Decoding the mpls header must be done by first byeswapping a 32bit bit
endian word into the local cpu endian and then bit shifting to extract
the pieces. There is no C bit-field that can represent a wire format
mpls header on a little endian machine as the low bits of the 20bit
label wind up in the wrong half of third byte. Therefore internally
everything is deal with in cpu native byte order except when writing
to and reading from a packet.
For management simplicity if a label is configured to forward out
an interface that is down the packet is dropped early. Similarly
if an network interface is removed rt_dev is updated to NULL
(so no reference is preserved) and any packets for that label
are dropped. Keeping the label entries in the kernel allows
the kernel label table to function as the definitive source
of which labels are allocated and which are not.

Currently, all real users of rhashtable default their grow and shrink
decision functions to rht_grow_above_75() and rht_shrink_below_30(),
so that there's currently no need to have this explicitly selectable.
It can/should be generic and private inside rhashtable until a real
use case pops up. Since we can make this private, we'll save us this
additional indirection layer and can improve insertion/deletion time
as well.

skb_gro_remcsum_init() initializes the gro_remcsum.delta member only,
leading to compiler warnings about a possibly uninitialized
gro_remcsum.offset member:
drivers/net/vxlan.c: In function ‘vxlan_gro_receive’:
drivers/net/vxlan.c:602: warning: ‘grc.offset’ may be used uninitialized in this function
net/ipv4/fou.c: In function ‘gue_gro_receive’:
net/ipv4/fou.c:262: warning: ‘grc.offset’ may be used uninitialized in this function
While these are harmless for now:
- skb_gro_remcsum_process() sets offset before changing delta,
- skb_gro_remcsum_cleanup() checks if delta is non-zero before
accessing offset,
it's safer to let the initialization function initialize all members.

When CONFIG_THERMAL is not enabled, it is better to introduce
equivalent dummy functions in the exported header than to
introduce #ifdeffery in drivers using the function.
This will prevent issues such as that reported in:
http://www.spinics.net/lists/linux-next/msg31573.html
While at it switch over to IS_ENABLED for thermal macros
to allow for thermal framework to be built as framework
and relevant APIs be usable by relevant drivers as a result.

Split DCACHE_FILE_TYPE into DCACHE_REGULAR_TYPE (dentries representing regular
files) and DCACHE_SPECIAL_TYPE (representing blockdev, chardev, FIFO and
socket files).
d_is_reg() and d_is_special() are added to detect these subtypes and
d_is_file() is left as the union of the two.
This allows a number of places that use S_ISREG(dentry->d_inode->i_mode) to
use d_is_reg(dentry) instead.

Add a DCACHE_FALLTHRU flag to indicate that, in a layered filesystem, this is
a virtual dentry that covers another one in a lower layer that should be used
instead. This may be recorded on medium if directory integration is stored
there.
The flag can be set with d_set_fallthru() and tested with d_is_fallthru().

Introduce some function for getting the inode (and also the dentry) in an
environment where layered/unioned filesystems are in operation.
The problem is that we have places where we need *both* the union dentry and
the lower source or workspace inode or dentry available, but we can only have
a handle on one of them. Therefore we need to derive the handle to the other
from that.
The idea is to introduce an extra field in struct dentry that allows the union
dentry to refer to and pin the lower dentry.

Pull MIPS updates from Ralf Baechle:
"This is the main pull request for MIPS:
- a number of fixes that didn't make the 3.19 release.
- a number of cleanups.
- preliminary support for Cavium's Octeon 3 SOCs which feature up to
48 MIPS64 R3 cores with FPU and hardware virtualization.
- support for MIPS R6 processors.
Revision 6 of the MIPS architecture is a major revision of the MIPS
architecture which does away with many of original sins of the
architecture such as branch delay slots. This and other changes in
R6 require major changes throughout the entire MIPS core
architecture code and make up for the lion share of this pull
request.
- finally some preparatory work for eXtendend Physical Address
support, which allows support of up to 40 bit of physical address
space on 32 bit processors"

The cevt-r4k driver used to call into the GIC driver to find whether the
timer was pending, but only with External Interrupt Controller (EIC)
mode, where the Cause.IP bits can't be used as they encode the interrupt
priority level (Cause.RIPL) instead.
However commit e9de688dac65 ("irqchip: mips-gic: Support local
interrupts") changed the condition from cpu_has_veic to gic_present.
This fails on cores such as P5600 which have a GIC but the local
interrupts aren't routable by the GIC, causing c0_compare_int_usable()
to consider the interrupt unusable so r4k_clockevent_init() fails.
The previous behaviour, added in commit 98b67c37db33 ("MIPS: Add EIC
support for GIC."), wasn't really correct either as far as I can tell,
since P5600 apparently supports EIC mode too, and in any case the use of
Cause.TI with r2 should have been sufficient anyway since commit
010c108d7af7 ("MIPS: PowerTV: Fix support for timer interrupts with > 64
external IRQs").
Therefore drop the call into the gic driver altogether, and add a
comment in c0_compare_int_pending() to clarify that Cause.TI does get
checked since MIPS r2.

The driver has to end unreturned commands at some point even if the
controller has not provided a completion. The driver tried to be safe by
deleting IO queues prior to ending all unreturned commands. That should
cause the controller to internally abort inflight commands, but IO queue
deletion request does not have to be successful, so all bets are off. We
still have to make progress, so to be extra safe, this patch doesn't
clear a queue to release the dma mapping for a command until after the
pci device has been disabled.
This patch removes the special handling during device initialization
so controller recovery can be done all the time. This is possible since
initialization is not inlined with pci probe anymore.

This creates a new class type for nvme devices to register their
management character devices with. This is so we do not rely on miscdev
to provide enough minors for as many nvme devices some people plan to
use. The previous limit was approximately 60 NVMe controllers, depending
on the platform and kernel. Now the limit is 1M, which ought to be enough
for anybody.
Since we have a new device class, it makes sense to attach the block
devices under this as well, so part of this patch moves the management
handle initialization prior to the namespaces discovery.

The original translation created collisions on Inquiry VPD 83 for many
existing devices. Newer specifications provide other ways to translate
based on the device's version can be used to create unique identifiers.
Version 1.1 provides an EUI64 field that uniquely identifies each
namespace, and 1.2 added the longer NGUID field for the same reason.
Both follow the IEEE EUI format and readily translate to the SCSI device
identification EUI designator type 2h. For devices implementing either,
the translation will use this type, defaulting to the EUI64 8-byte type if
implemented then NGUID's 16 byte version if not. If neither are provided,
the 1.0 translation is used, and is updated to use the SCSI String format
to guarantee a unique identifier.
Knowing when to use the new fields depends on the nvme controller's
revision. The NVME_VS macro was not decoding this correctly, so that is
fixed in this patch and moved to a more appropriate place.
Since the Identify Namespace structure required an update for the NGUID
field, this patch adds the remaining new 1.2 fields to the structure.

Adds support for NVMe metadata formats and exposes block devices for
all namespaces regardless of their format. Namespace formats that are
unusable will have disk capacity set to 0, but a handle to the block
device is created to simplify device management. A namespace is not
usable when the format requires host interleave block and metadata in
single buffer, has no provisioned storage, or has better data but failed
to register with blk integrity.
The namespace has to be scanned in two phases to support separate
metadata formats. The first establishes the sector size and capacity
prior to invoking add_disk. If metadata is required, the capacity will
be temporarilly set to 0 until it can be revalidated and registered with
the integrity extenstions after add_disk completes.
The driver relies on the integrity extensions to provide the metadata
buffer. NVMe requires this be a single physically contiguous region,
so only one integrity segment is allowed per command. If the metadata
is used for T10 PI, the driver provides mappings to save and restore
the reftag physical block translation. The driver provides no-op
functions for generate and verify if metadata is not used for protection
information. This way the setup is always provided by the block layer.
If a request does not supply a required metadata buffer, the command
is failed with bad address. This could only happen if a user manually
disables verify/generate on such a disk. The only exception to where
this is okay is if the controller is capable of stripping/generating
the metadata, which is possible on some types of formats.
The metadata scatter gather list now occupies the spot in the nvme_iod
that used to be used to link retryable IOD's, but we don't do that
anymore, so the field was unused.

Newer Blackfin boards use pinctrl API to manage pins and the legacy
peripherial lists are not useful on them. Let's move pin lists into
platform data so older boards can still use them and newer boards can use
the modern API.

There haven't been any I2C driver that use the legacy suspend/resume
callbacks for a while now and new drivers are supposed to use PM ops. So
remove support for legacy suspend/resume for I2C drivers.
Since there aren't any special bus specific things to do during
suspend/resume and since the PM core will automatically fallback directly to
using the device's PM ops if no bus PM ops are specified there is no need to
have any I2C bus PM ops.

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

After the clk API change to return a per-user clock instance, both the
struct clk_core and struct clk pointers from the hw clock needs to be
assigned to clock that share the same state.
In the future the struct clk_core will be removed and this is going to
change again so to avoid having to change the assignments twice in all
the drivers, add a helper function to have an indirection level.
