stmmac_probe_config_dt does a kzalloc dma_cfg.
pci glue layer does kzalloc dma_cfg explicitly, so all current

devicetree binding for stmmac states:
- compatible: Should be "snps,dwmac-<ip_version>", "snps,dwmac"
For backwards compatibility: "st,spear600-gmac" is also supported.
Previously, when specifying "snps,dwmac-4.10a", "snps,dwmac" as your
compatible string, plat_stmmacenet_data would have both has_gmac and
has_gmac4 set.
This would lead to stmmac_hw_init calling dwmac1000_setup rather than
dwmac4_setup, resulting in a non-functional driver.
This happened since the check for has_gmac is done before the check for
has_gmac4. However, the order should not matter, so it does not make sense
to have both set.
If something is valid for both, you should do as the stmmac_interrupt does:
if (priv->plat->has_gmac || priv->plat->has_gmac4) ...
The places where it was obvious that the author actually meant
if (has_gmac || has_gmac4) rather than if (has_gmac) has been updated.

For backwards compatibility: "st,spear600-gmac" is also supported.
Since dwmac-generic.c calls stmmac_probe_config_dt explicitly,
another alternative would have been to remove all compatible strings
other than "snps,dwmac" and "st,spear600-gmac" from dwmac-generic.c.
However, that would probably do more good than harm, since when trying
to figure out what hardware a certain driver supports, you usually look
at the compatible strings in the struct of_device_id, and not in some
function defined in a completely different file.

This function sets req->r_locked_dir which is supposed to indicate to
ceph_fill_trace that the parent's i_rwsem is locked for write.
Unfortunately, there is no guarantee that the dir will be locked when
d_revalidate is called, so we really don't want ceph_fill_trace to do
any dcache manipulation from this context. Clear req->r_locked_dir since
it's clearly not safe to do that.
What we really want to know with d_revalidate is whether the dentry
still points to the same inode. ceph_fill_trace installs a pointer to
the inode in req->r_target_inode, so we can just compare that to
d_inode(dentry) to see if it's the same one after the lookup.
Also, since we aren't generally interested in the parent here, we can
switch to using a GETATTR to hint that to the MDS, which also means that
we only need to reserve one cap.
Finally, just remove the d_unhashed check. That's really outside the
purview of a filesystem's d_revalidate. If the thing became unhashed
while we're checking it, then that's up to the VFS to handle anyway.

Netfilter/IPVS updates for net-next
The following patchset contains a large Netfilter update for net-next,
to summarise:
1) Add support for stateful objects. This series provides a nf_tables
native alternative to the extended accounting infrastructure for
nf_tables. Two initial stateful objects are supported: counters and
quotas. Objects are identified by a user-defined name, you can fetch
and reset them anytime. You can also use a maps to allow fast lookups
using any arbitrary key combination. More info at:
http://marc.info/?l=netfilter-devel&m=148029128323837&w=2
2) On-demand registration of nf_conntrack and defrag hooks per netns.
Register nf_conntrack hooks if we have a stateful ruleset, ie.
state-based filtering or NAT. The new nf_conntrack_default_on sysctl
enables this from newly created netnamespaces. Default behaviour is not
modified. Patches from Florian Westphal.
3) Allocate 4k chunks and then use these for x_tables counter allocation
requests, this improves ruleset load time and also datapath ruleset
evaluation, patches from Florian Westphal.
4) Add support for ebpf to the existing x_tables bpf extension.
From Willem de Bruijn.
5) Update layer 4 checksum if any of the pseudoheader fields is updated.
This provides a limited form of 1:1 stateless NAT that make sense in
specific scenario, eg. load balancing.
6) Add support to flush sets in nf_tables. This series comes with a new
set->ops->deactivate_one() indirection given that we have to walk
over the list of set elements, then deactivate them one by one.
The existing set->ops->deactivate() performs an element lookup that
we don't need.
7) Two patches to avoid cloning packets, thus speed up packet forwarding
via nft_fwd from ingress. From Florian Westphal.
8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
prevent infinite loops, patch from Dwip Banerjee. And one minor
refactoring from Gao feng.
9) Revisit recent log support for nf_tables netdev families: One patch
to ensure that we correctly handle non-ethernet packets. Another
patch to add missing logger definition for netdev. Patches from
Liping Zhang.
10) Three patches for nft_fib, one to address insufficient register
initialization and another to solve incorrect (although harmless)
byteswap operation. Moreover update xt_rpfilter and nft_fib to match
lbcast packets with zeronet as source, eg. DHCP Discover packets
(0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.
11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
been broken in many-cast mode for some little time, let's give them a
chance by placing them at the same level as other existing protocols.
Thus, users don't explicitly have to modprobe support for this and
NAT rules work for them. Some people point to the lack of support in
SOHO Linux-based routers that make deployment of new protocols harder.
I guess other middleboxes outthere on the Internet are also to blame.
Anyway, let's see if this has any impact in the midrun.
12) Skip software SCTP software checksum calculation if the NIC comes
with SCTP checksum offload support. From Davide Caratti.
13) Initial core factoring to prepare conversion to hook array. Three
patches from Aaron Conole.
14) Gao Feng made a wrong conversion to switch in the xt_multiport
extension in a patch coming in the previous batch. Fix it in this
batch.
15) Get vmalloc call in sync with kmalloc flags to avoid a warning
and likely OOM killer intervention from x_tables. From Marcelo
Ricardo Leitner.
16) Update Arturo Borrero's email address in all source code headers.

(UDP) on the XL710 MAC, since there was a product decision to defeature
it. Fixed a previous refactor of active filters which caused issues in
the accounting of active_filters. Remaining work was done in the VLAN
filters to improve readability and simplify code as much as possible
to reduce inconsistencies.
Alex fixes foul budget accounting in core code by returning actual
work done, capped to budget-1.

SCT Write Same support had been introduced with
commit 7b20309428 ("libata: Add support for SCT Write Same")
Some problems, namely excessive userspace segfaults, had been reported at
http://lkml.kernel.org/r/20160908192736.GA4356@gmail.com
This lead to commit 0ce1b18c42 ("libata: Some drives failing on
SCT Write Same") which strived to disable SCT Write Same on !ZAC devices.
Due to the way this was done and to the logic in sd_config_write_same(),
this didn't work for those devices that have
->max_ws_blocks > SD_MAX_WS10_BLOCKS: for these, ->no_write_same and
->max_write_same_sectors would still be non-zero,
but ->ws10 == ->ws16 == 0. This would cause sd_setup_write_same_cmnd() to
demultiplex REQ_OP_WRITE_SAME requests to WRITE_SAME, and these in turn
aren't supported by libata-scsi:
EXT4-fs (dm-1): Delayed block allocation failed for inode 2625094 at
logical offset 2032 with max blocks 2 with error 121
EXT4-fs (dm-1): This should not happen!! Data will be lost
121 == EREMOTEIO is what scsi_io_completion() asserts in case of
invalid opcodes.
Back to the original problem of userspace segfaults: this can be tracked
down to ata_format_sct_write_same() overwriting the input page. Sometimes,
this page is ZERO_PAGE(0) which ceases to be filled with zeros from that
point on. Since ZERO_PAGE(0) is used for userspace .bss mappings, code of
the following is doomed:
static char *a = NULL; /* .bss */
...
if (a)
*a = 'a';
This problem is not solved by disabling SCT Write Same for !ZAC devices
only.
It can certainly be fixed, but the final release is quite close -- so
disable SCT Write Same for all ATA devices rather than introducing some
SCT key buffer allocation schemes at this point.

The eLCDIF IP of the i.MX 7 SoC knows multiple clocks and lists them
separately:
Clock Clock Root Description
apb_clk MAIN_AXI_CLK_ROOT AXI clock
pix_clk LCDIF_PIXEL_CLK_ROOT Pixel clock
ipg_clk_s MAIN_AXI_CLK_ROOT Peripheral access clock
All of them are switched by a single gate, which is part of the
IMX7D_LCDIF_PIXEL_ROOT_CLK clock. Hence using that clock also for
the AXI bus clock (clock-name "axi") makes sure the gate gets
enabled when accessing registers.
There seem to be no separate AXI display clock, and the clock is
optional. Hence remove the dummy clock.

After commit 61e84623ac ("net: centralize net_device min/max MTU checking"),
the mtu range for dummy device becomes [68, 1500].
This patch extends it to [0, 65535].

Since commit 61e84623ac ("net: centralize net_device min/max MTU checking"),
mtu range is checked at dev_set_mtu().
This patch adds min_mtu for nlmon device and remove unnecessary
ndo_change_mtu() function.

Commit 3e3aaf6494 ("phy: fix mdiobus module safety") fixed the way we
dealt with MDIO bus module reference count, but sort of introduced a
regression in that, if an Ethernet driver registers its own MDIO bus
driver, as is common, we will end up with the Ethernet driver's
module->refnct set to 1, thus preventing this driver from any removal.
Fix this by comparing the network device's device driver owner against
the MDIO bus driver owner, and only if they are different, increment the
MDIO bus module refcount.

When free macvlan_port in macvlan_port_destroy, it is safe to free
directly because netdev_rx_handler_unregister could enforce one
grace period.
So it is unnecessary to use kfree_rcu for macvlan_port.

There are two functions which would free the ipvl_port now. The first
is ipvlan_port_create. It frees the ipvl_port in the error handler,
so it could kfree it directly. The second is ipvlan_port_destroy. It
invokes netdev_rx_handler_unregister which enforces one grace period
by synchronize_net firstly, so it also could kfree the ipvl_port
directly and safely.
So it is unnecessary to use kfree_rcu to free ipvl_port.
