Remove the switch block in l2tp_nl_cmd_session_create() that
checks pseudowire-specific parameters since just L2TP_PWTYPE_ETH and
L2TP_PWTYPE_PPP are currently supported and no actual checks are
performed. Moreover the L2TP_PWTYPE_IP/default case presents a harmless
issue in error handling (break instead of goto out_tunnel)

l2tp: set l2specific_len based on l2specific_type
Do not rely on l2specific_len value provided by userspace but set sublayer
length according to l2specific_type.
Mark L2TP_ATTR_L2SPEC_LEN attribute as not used
Changes since v2:
- drop the patch related to a fix in the switch default case in
l2tp_nl_cmd_session_create()
- use L2SPECTYPE_NONE as default case in l2tp_get_l2specific_len()
Changes since v1:
- remove l2specific_len parameter
- add sanity check on l2specific_type provided by userspace

Remove l2specific_len dependency while building l2tpv3 header or
parsing the received frame since default L2-Specific Sublayer is
always four bytes long and we don't need to rely on a user supplied
value.
Moreover in l2tp netlink code there are no sanity checks to
enforce the relation between l2specific_len and l2specific_type,
so sending a malformed netlink message is possible to set
l2specific_type to L2TP_L2SPECTYPE_DEFAULT (or even
L2TP_L2SPECTYPE_NONE) and set l2specific_len to a value greater than
4 leaking memory on the wire and sending corrupted frames.

We have various small DT fixes, and one important regression fix:
The recent device tree bugfixes that were intended to address issues that
'dtc' started warning about in 4.15 fixed various USB PHY device nodes,
but it turns out that we had code that depended on those nodes being
incorrect and the probe failing with a particular error code. With the
workaround we can also deal with correct device nodes.
The DT fixes include:
- Allwinner A10 and A20 had the display pipeline set up incorrectly
(introduced in v4.15)
- The Altera PMU lacked an interrupt-parent (never worked)
- Pin muxing on the Openblocks A7 (never worked)
- Clocks might get set up wrong on Armada 7K/8K (4.15 regression)
We now have additional device tree patches to address all the remaining
warnings introduced in 4.15, but decided to queue them for 4.16 instead,
to avoid risking another regression like the USB PHY thing mentioned
above.

doesn't actually prevent CPU hotplug as it suggests, so remove it.
Two updates to the recently merged RFI flush code. Wire up the generic sysfs
file to report the status, and add a debugfs file to allow enabling/disabling it
at runtime.
Two updates to xmon, one to add the RFI flush related fields to the paca dump,

And one minor fix to add a missing include of linux/types.h in asm/hvcall.h, not
seen to break the build in upstream, but correct anyway.

There are a couple of problems with the decodecode script and arm64:
1. AArch64 objdump refuses to disassemble .4byte directives as instructions,
insisting that they are data values and displaying them as:
a94153f3 .word 0xa94153f3 <-- trapping instruction
This is resolved by using the .inst directive instead.
2. Disassembly of branch instructions attempts to provide the target as
an offset from a symbol, e.g.:
0: 34000082 cbz w2, 10 <.text+0x10>
however this falls foul of the grep -v, which matches lines containing
".text" and ends up removing all branch instructions from the dump.
This patch resolves both issues by using the .inst directive for 4-byte
quantities on arm64 and stripping the resulting binaries (as is done on
arm already) to remove the mapping symbols.

James reported a bug in swap paging-in from his testing. It is that
do_swap_page doesn't release locked page so system hang-up happens due
to a deadlock on PG_locked.
It was introduced by 0bcac06f27d7 ("mm, swap: skip swapcache for swapin
of synchronous device") because I missed swap cache hit places to update
swapcache variable to work well with other logics against swapcache in
do_swap_page.
This patch fixes it.

Several reasons for this:
* Several modules maintain internal version numbers, that they print at
boot/module load time, that are not exposed to userspace, as a
primitive mechanism to make revision number control from the earlier
days of Netfilter.
* IPset shows the protocol version at boot/module load time, instead
display this via module description, as Jozsef suggested.
* Remove copyright notice at boot/module load time in two spots, the
Netfilter codebase is a collective development effort, if we would
have to display copyrights for each contributor at boot/module load
time for each extensions we have, we would probably fill up logs with
lots of useless information - from a technical standpoint.
So let's be consistent and remove them all.

Stefan Wahren reports a problem with a warning fix that was merged
for v4.15: we had lots of device nodes with a 'phys' property pointing
to a device node that is not compliant with the binding documented in
Documentation/devicetree/bindings/phy/phy-bindings.txt
This generally works because USB HCD drivers that support both the generic
phy subsystem and the older usb-phy subsystem ignore most errors from
phy_get() and related calls and then use the usb-phy driver instead.
However, it turns out that making the usb-nop-xceiv device compatible with
the generic-phy binding changes the phy_get() return code from -EINVAL to
-EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns
-EPROBE_DEFER from its probe function rather than ignoring the failure,
breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is
enabled. The same code is used in the dwc3 driver and the usb_add_hcd()
function, so a reasonable assumption would be that many other platforms
are affected as well.
I have reviewed all the related patches and concluded that "usb-nop-xceiv"
is the only USB phy that is affected by the change, and since it is by far
the most commonly referenced phy, all the other USB phy drivers appear
to be used in ways that are are either safe in DT (they don't use the
'phys' property), or in the driver (they already ignore -EPROBE_DEFER
from generic-phy when usb-phy is available).
To work around the problem, this adds a special case to _of_phy_get()
so we ignore any PHY node that is compatible with "usb-nop-xceiv",
as we know that this can never load no matter how much we defer. In the
future, we might implement a generic-phy driver for "usb-nop-xceiv"
and then remove this workaround.
Since we generally want older kernels to also want to work with the
fixed devicetree files, it would be good to backport the patch into
stable kernels as well (3.13+ are possibly affected), even though they
don't contain any of the patches that may have caused regressions.

The DRM driver most notably, but also out of tree drivers (for now) like
the VPU or GPU drivers, are quite big consumers of large, contiguous memory
buffers. However, the sunxi_defconfig doesn't enable CMA in order to
mitigate that, which makes them almost unusable.
Enable it to make sure it somewhat works.

/proc has been ignoring struct file_operations::owner field for 10 years.
Specifically, it started with commit 786d7e1612f0b0adb6046f19b906609e4fe8b1ba
("Fix rmmod/read/write races in /proc entries"). Notice the chunk where
inode->i_fop is initialized with proxy struct file_operations for
regular files:
- if (de->proc_fops)
- inode->i_fop = de->proc_fops;
+ if (de->proc_fops) {
+ if (S_ISREG(inode->i_mode))
+ inode->i_fop = &proc_reg_file_ops;
+ else
+ inode->i_fop = de->proc_fops;
+ }
VFS stopped pinning module at this point.

The basic SNMP ALG parse snmp ASN.1 payload
however, since 2012 linux kernel provide ASN.1 decoder library.
If we use ASN.1 decoder in the /lib/asn1_decoder.c, we can remove
about 1000 line of ASN.1 parsing routine.
To use asn1_decoder.c, we should write mib file(nf_nat_snmp_basic.asn1)
then /script/asn1_compiler.c makes *-asn1.c and *-asn1.h file
at the compiletime.(nf_nat_snmp_basic-asn1.c, nf_nat_snmp_basic-asn1.h)
The nf_nat_snmp_basic.asn1 is made by RFC1155, RFC1157, RFC1902, RFC1905,
RFC2578, RFC3416. of course that mib file supports only the basic SNMP ALG.
Previous SNMP ALG mangles only first octet of IPv4 address.
but after this patch, the SNMP ALG mangles whole IPv4 Address.
And SNMPv3 is not supported.
I tested with snmp commands such ans snmpd, snmpwalk, snmptrap.
