For irq associated with hierarchy irqdomains, there will be multiple
irq_datas for one irq_desc. So enhance irq_data_to_desc() to support
hierarchy irqdomain. Also export irq_data_to_desc() as an inline

This get_info handler will simply dispatch to the appropriate
existing inet protocol handler.
This patch also includes a new netlink attribute
(INET_DIAG_PROTOCOL). This attribute is currently only used
for multicast messages. Without this attribute, there is no
way of knowing the IP protocol used by the socket information
being broadcast. This attribute is not necessary in the 'dump'
variant of this protocol (though it could easily be added)
because dump requests are issued for specific family/protocol
pairs.

Netfilter updates for net-next
This a bit large (and late) patchset that contains Netfilter updates for
net-next. Most relevantly br_netfilter fixes, ipset RCU support, removal of
x_tables percpu ruleset copy and rework of the nf_tables netdev support. More
specifically, they are:
1) Warn the user when there is a better protocol conntracker available, from
Marcelo Ricardo Leitner.
2) Fix forwarding of IPv6 fragmented traffic in br_netfilter, from Bernhard
Thaler. This comes with several patches to prepare the change in first place.
3) Get rid of special mtu handling of PPPoE/VLAN frames for br_netfilter. This
is not needed anymore since now we use the largest fragment size to
refragment, from Florian Westphal.
4) Restore vlan tag when refragmenting in br_netfilter, also from Florian.
5) Get rid of the percpu ruleset copy in x_tables, from Florian. Plus another
follow up patch to refine it from Eric Dumazet.
6) Several ipset cleanups, fixes and finally RCU support, from Jozsef Kadlecsik.
7) Get rid of parens in Netfilter Kconfig files.
8) Attach the net_device to the basechain as opposed to the initial per table
approach in the nf_tables netdev family.
9) Subscribe to netdev events to detect the removal and registration of a
device that is referenced by a basechain.

In case the net_device is gone, we have to unregister the hooks and put back
the reference on the net_device object. Once it comes back, register them
again. This also covers the device rename case.
This patch also adds a new flag to indicate that the basechain is disabled, so
their hooks are not registered. This flag is used by the netdev family to
handle the case where the net_device object is gone. Currently this flag is not
exposed to userspace.

The device is part of the hook configuration, so instead of a global

If updating journal superblock fails after journal data has been
flushed, the error is omitted and this will mislead the caller as a
normal case. In ocfs2, the checkpoint will be treated successfully
and the other node can get the lock to update. Since the sb_start is
still pointing to the old log block, it will rewrite the journal data
during journal recovery by the other node. Thus the new updates will
be overwritten and ocfs2 corrupts. So in above case we have to return
the error, and ocfs2_commit_cache will take care of the error and
prevent the other node to do update first. And only after recovering
journal it can do the new updates.

After Florian patches, there is no need for XT_TABLE_INFO_SZ anymore :
Only one copy of table is kept, instead of one copy per cpu.
We also can avoid a dereference if we put table data right after
xt_table_info. It reduces register pressure and helps compiler.
Then, we attempt a kmalloc() if total size is under order-3 allocation,
to reduce TLB pressure, as in many cases, rules fit in 32 KB.

Commit 1b84f2a4cd ("mfd: cros_ec: Use fixed size arrays to transfer
data with the EC") modified the struct cros_ec_command fields to not
use pointers for the input and output buffers and use fixed length
arrays instead.
This change was made because the cros_ec ioctl API uses that struct
cros_ec_command to allow user-space to send commands to the EC and
to get data from the EC. So using pointers made the API not 64-bit
safe. Unfortunately this approach was not flexible enough for all
the use-cases since there may be a need to send larger commands
on newer versions of the EC command protocol.
So to avoid to choose a constant length that it may be too big for
most commands and thus wasting memory and CPU cycles on copy from
and to user-space or having a size that is too small for some big
commands, use a zero-length array that is both 64-bit safe and
flexible. The same buffer is used for both output and input data
so the maximum of these values should be used to allocate it.

Move the contents of the include/linux/nx842.h header file into the
drivers/crypto/nx/nx-842.h header file. Remove the nx842.h header
file and its entry in the MAINTAINERS file.
The include/linux/nx842.h header originally was there because the
crypto/842.c driver needed it to communicate with the nx-842 hw
driver. However, that crypto compression driver was moved into
the drivers/crypto/nx/ directory, and now can directly include the
nx-842.h header. Nothing else needs the public include/linux/nx842.h
header file, as all use of the nx-842 hardware driver will be through
the "842-nx" crypto compression driver, since the direct nx-842 api is
very limited in the buffer alignments and sizes that it will accept,
and the crypto compression interface handles those limitations and
allows any alignment and size buffers.

Merge tag 'sound-4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound fixes from Takashi Iwai:
"Most of commits are regression fixes for HD-audio: a few corner case
fixes for regmap transition, and i915 binding issues.
In addition, a quirk for another USB-audio device supporting DSD"
* tag 'sound-4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound:
ALSA: hda - Abort the probe without i915 binding for HSW/BDW
ALSA: hda - Re-add the lost fake mute support
ALSA: hda - Continue probing even if i915 binding fails
ALSA: hda - Don't actually write registers for caps overwrites
ALSA: hda - fix number of devices query on hotplug
ALSA: usb-audio: add native DSD support for JLsounds I2SoverUSB
->auto_asconf_splist is per namespace and mangled by functions like
sctp_setsockopt_auto_asconf() which doesn't guarantee any serialization.
Also, the call to inet_sk_copy_descendant() was backuping
->auto_asconf_list through the copy but was not honoring
->do_auto_asconf, which could lead to list corruption if it was
different between both sockets.
This commit thus fixes the list handling by using ->addr_wq_lock
spinlock to protect the list. A special handling is done upon socket
creation and destruction for that. Error handlig on sctp_init_sock()
will never return an error after having initialized asconf, so
sctp_destroy_sock() can be called without addrq_wq_lock. The lock now
will be take on sctp_close_sock(), before locking the socket, so we
don't do it in inverse order compared to sctp_addr_wq_timeout_handler().
Instead of taking the lock on sctp_sock_migrate() for copying and
restoring the list values, it's preferred to avoid rewritting it by
implementing sctp_copy_descendant().
Issue was found with a test application that kept flipping sysctl
default_auto_asconf on and off, but one could trigger it by issuing
simultaneous setsockopt() calls on multiple sockets or by
creating/destroying sockets fast enough. This is only triggerable
locally.

Replace rwlock_t with spinlock_t in "struct ip_set" and change the locking
accordingly. Convert the comment extension into an rcu-avare object. Also,
simplify the timeout routines.

When elements added to a hash:* type of set and resizing triggered,
parallel listing could start to list the original set (before resizing)
and "continue" with listing the new set. Fix it by references and
using the original hash table for listing. Therefore the destroying of
the original hash table may happen from the resizing or listing functions.

Commit "Simplify cidr handling for hash:*net* types" broke the cidr
handling for the hash:*net* types when the sets were used by the SET
target: entries with invalid cidr values were added to the sets.
Reported by Jonathan Johnson.
Testsuite entry is added to verify the fix.

__skb_header_pointer() returns a pointer that must be checked.
Fixes infinite loop reported by Alexei, and add __must_check to
catch these errors earlier.

This patch just redefine the unique id of supported external connectors without
'enum extcon' type. Because unique id would be used on devictree file(*.dts) to
indicate the specific external connectors like key number of input framework.
So, I have the plan to move this definitions to following header file which
includes the unique id of supported external connectors.
- include/dt-bindings/extcon/extcon.h
Fixes: 2a9de9c0f0 ("extcon: Use the unique id for external connector instead of string")
