Cavium CNN55XX: fix broken default Kconfig entry
Every developer always thinks that _their_ code is so special and
magical that it should be enabled by default.
And most of them are completely and utterly wrong. That's definitely
the case when you write a specialty driver for a very unsual "security
processor". It does *not* get to mark itself as "default m".
If you solve world hunger, and make a driver that cures people of
cancer, by all means enable it by default. But afaik, the Cavium
CNN55XX does neither.

parisc: ->mapping_error
DMA_ERROR_CODE already went away in linux-next, but parisc unfortunately
added a new instance of it without any review as far as I can tell.

GFS2: constify attribute_group structures.
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

gfs2: gfs2_create_inode: Keep glock across iput
On failure, keep the inode glock across the final iput of the new inode
so that gfs2_evict_inode doesn't have to re-acquire the glock. That
way, gfs2_evict_inode won't need to revalidate the block type.

gfs2: Get rid of flush_delayed_work in gfs2_evict_inode
So far, gfs2_evict_inode clears gl->gl_object and then flushes the glock
work queue to make sure that inode glops which dereference gl->gl_object
have finished running before the inode is destroyed. However, flushing
the work queue may do more work than needed, and in particular, it may
call into DLM, which we want to avoid here. Use a bit lock
(GIF_GLOP_PENDING) to synchronize between the inode glops and
gfs2_evict_inode instead to get rid of the flushing.
In addition, flush the work queues of existing glocks before reusing
them for new inodes to get those glocks into a known state: the glock
state engine currently doesn't handle glock re-appropriation correctly.
(We may be able to fix the glock state engine instead later.)

net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017,
advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not
supported (see note below Table 5 (4-Level Strap Pins)).
There are some boards which have the pin strapped this way and need
software workaround suggested by the data manual. Bit[7] of
Configuration Register 4 (address 0x0031) must be cleared to 0. This
ensures proper operation of the PHY.
Implement driver support for device-tree property meant to advertise
the wrong strapping.

advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not

It further advises that if a board has this pin strapped in mode 1 and
mode 2, then to ensure proper operation of the PHY, a software workaround
must be implemented.
Since it is not possible to detect in software if RX_DV/RX_CTRL pin is
incorrectly strapped, add a device-tree property for the board to
advertise this and allow corrective action in software.

nfp: default to chained metadata prepend format
ABI 4.x introduced the chained metadata format and made it the
only one possible. There are cases, however, where the old
format is preferred - mostly to make interoperation with VFs
using ABI 3.x easier for the datapath. In ABI 5.x we allowed
for more flexibility by selecting the metadata format based
on capabilities. The default was left to non-chained.
In case of fallback traffic, there is no capability telling the
driver there may be chained metadata. With a very stripped-
-down FW the default old metadata format would be selected
making the driver drop all fallback traffic.
This patch changes the default selection in the driver. It
should not hurt with old firmwares, because if they don't
advertise RSS they will not produce metadata anyway. New
firmwares advertising ABI 5.x, however, can depend on the
driver defaulting to chained format.

nfp: improve order of interfaces in breakout mode
For historical reasons we enumerate the vNICs in order. This means
that if user configures breakout on a multiport card, the first
interface of the second port will have its MAC address changed.
What's worse, when moved from static information (HWInfo) to using
management FW (NSP), more features started depending on the port ids.
Right now in case of breakout first subport of the second port and
second subport of the first port will have their link info swapped.
Revise the ordering scheme so that first subport maintains its address.
Side effect of this change is that we will use base lane ids in
devlink (i.e. 40G ports will be 4 ids apart), e.g.:
pci/0000:04:00.0/0: type eth netdev p6p1
pci/0000:04:00.0/4: type eth netdev p6p2
Note that behaviour of phys_port_id is not changed since there is
a separate id number for the subport there.

bpf: fix return in load_bpf_file
The function load_bpf_file ignores the return value of
load_and_attach(), so even if load_and_attach() returns an error,
load_bpf_file() will return 0.
Now, load_bpf_file() can call load_and_attach() multiple times and some
can succeed and some could fail. I think the correct behavor is to
return error on the first failed load_and_attach().

mpls: route get support
This patch adds RTM_GETROUTE doit handler for mpls routes.
Input:
RTA_DST - input label
RTA_NEWDST - labels in packet for multipath selection
By default the getroute handler returns matched
nexthop label, via and oif
With RTM_F_FIB_MATCH flag, full matched route is
returned.

Cause is a call to dma_coerce_mask_and_coherenet in parport_pc_probe_port,
which PARISC DMA API doesn't handle very nicely. This commit gives back
DMA_ERROR_CODE for DMA API calls, if device isn't capable of DMA
transaction.

ARM64: dts: marvell: armada37xx: Fix timer interrupt specifiers
Contrary to popular belief, PPIs connected to a GICv3 to not have
an affinity field similar to that of GICv2. That is consistent
with the fact that GICv3 is designed to accomodate thousands of
CPUs, and fitting them as a bitmap in a byte is... difficult.
