The 'bcm-phy-lib.c', added as a part of the commit
"net: phy: Add Broadcom phy library for common interfaces"
was missing the module license. This was causing an issue
when the library is built as a module; "module license
'unspecified' taints kernel".
This patch fixes the issue by adding the module license,
author and description to the bcm-phy-lib.c file.

netlink_dump() allocates skb based on the calculated min_dump_alloc or
a per socket max_recvmsg_len.
min_alloc_size is maximum space required for any single netdev
attributes as calculated by rtnl_calcit().
max_recvmsg_len tracks the user provided buffer to netlink_recvmsg.
It is capped at 16KiB.
The intention is to avoid small allocations and to minimize the number
of calls required to obtain dump information for all net devices.
netlink_dump packs as many small messages as could fit within an skb
that was sized for the largest single netdev information. The actual
space available within an skb is larger than what is requested. It could
be much larger and up to near 2x with align to next power of 2 approach.
Allowing netlink_dump to use all the space available within the
allocated skb increases the buffer size a user has to provide to avoid
truncaion (i.e. MSG_TRUNG flag set).
It was observed that with many VLANs configured on at least one netdev,
a larger buffer of near 64KiB was necessary to avoid "Message truncated"
error in "ip link" or "bridge [-c[ompressvlans]] vlan show" when
min_alloc_size was only little over 32KiB.
This patch trims skb to allocated size in order to allow the user to
avoid truncation with more reasonable buffer size.

A dhcp server may provide parameters to a client from a pool of IP
addresses and using a shared rootfs, or provide a specific set of
parameters for a specific client, usually using the MAC address to
identify each client individually. The dhcp protocol also specifies
a client-id field which can be used to determine the correct
parameters to supply when no MAC address is available. There is
currently no way to tell the kernel to supply a specific client-id,
only the userspace dhcp clients support this feature, but this can
not be used when the network is needed before userspace is available
such as when the root filesystem is on NFS.
This patch is to be able to do something like "ip=dhcp,client_id_type,
client_id_value", as a kernel parameter to enable the kernel to
identify itself to the server.

ACPI SSCN/FMCN methods were originally added because then the platform can
provide the most accurate HCNT/LCNT values to the driver. However, this
seems not to be true for Dell Inspiron 7348 where using these causes the
touchpad to fail in boot:
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: i2c_dw_handle_tx_abort: lost arbitration
i2c_hid i2c-DLL0675:00: failed to retrieve report from device.
i2c_designware INT3433:00: controller timed out
The values received from ACPI are (in fast mode):
HCNT: 72
LCNT: 160
this translates to following timings (input clock is 100MHz on Broadwell):
tHIGH: 720 ns (spec min 600 ns)
tLOW: 1600 ns (spec min 1300 ns)
Bus period: 2920 ns (assuming 300 ns tf and tr)
Bus speed: 342.5 kHz
Both tHIGH and tLOW are within the I2C specification.
The calculated values when ACPI parameters are not used are (in fast mode):
HCNT: 87
LCNT: 159
which translates to:
tHIGH: 870 ns (spec min 600 ns)
tLOW: 1590 ns (spec min 1300 ns)
Bus period 3060 ns (assuming 300 ns tf and tr)
Bus speed 326.8 kHz
These values are also within the I2C specification.
Since both ACPI and calculated values meet the I2C specification timing
requirements it is hard to say why the touchpad does not function properly
with the ACPI values except that the bus speed is higher in this case (but
still well below the max 400kHz).
Solve this by adding DMI quirk to the driver that disables using ACPI
parameters on this particulare machine.

Greg reported crashes hitting the following check in __sk_backlog_rcv()
BUG_ON(!sock_flag(sk, SOCK_MEMALLOC));
The pfmemalloc bit is currently checked in sk_filter().
This works correctly for TCP, because sk_filter() is ran in
tcp_v[46]_rcv() before hitting the prequeue or backlog checks.
For UDP or other protocols, this does not work, because the sk_filter()
is ran from sock_queue_rcv_skb(), which might be called _after_ backlog
queuing if socket is owned by user by the time packet is processed by
softirq handler.

The following two locking commits in the DAX code:
commit 843172978bb9 ("dax: fix race between simultaneous faults")
commit 46c043ede471 ("mm: take i_mmap_lock in unmap_mapping_range() for DAX")
introduced a number of deadlocks and other issues which need to be fixed
for the v4.3 kernel. The list of issues in DAX after these commits
(some newly introduced by the commits, some preexisting) can be found
here:
https://lkml.org/lkml/2015/9/25/602 (Subject: "Re: [PATCH] dax: fix deadlock in __dax_fault").
This undoes most of the changes introduced by those two commits,
essentially returning us to the DAX locking scheme that was used in
v4.2.

Commit 3716001bcb7f ("deb-pkg: add source package") added the ability to
create a debian changelog file. This exposed that previously the
builddeb script hasn't cleared debian/files between builds.
As debian/files keeps accumulating entries, the changes file will end up
growing indefinelty. With outdated entries in debian/files, builddeb
script will exit with failure. This regression impacts those who use
"make deb-pkg" target to build kernel into a .deb package and never use
"make mrproper" or other means to clean kernel tree from generated
directories.
To fix the regression, remove debian/files before starting build and in
the generated clean rule.

Commit 6afdb859b710 ("mm: do not ignore mapping_gfp_mask in page cache
allocation paths") has caught some users of hardcoded GFP_KERNEL used in
the page cache allocation paths. This, however, wasn't complete and
there were others which went unnoticed.
Dave Chinner has reported the following deadlock for xfs on loop device:
: With the recent merge of the loop device changes, I'm now seeing
: XFS deadlock on my single CPU, 1GB RAM VM running xfs/073.
:
: The deadlocked is as follows:
:
: kloopd1: loop_queue_read_work
: xfs_file_iter_read
: lock XFS inode XFS_IOLOCK_SHARED (on image file)
: page cache read (GFP_KERNEL)
: radix tree alloc
: memory reclaim
: reclaim XFS inodes
: log force to unpin inodes
: <wait for log IO completion>
:
: xfs-cil/loop1: <does log force IO work>
: xlog_cil_push
: xlog_write
: <loop issuing log writes>
: xlog_state_get_iclog_space()
: <blocks due to all log buffers under write io>
: <waits for IO completion>
:
: kloopd1: loop_queue_write_work
: xfs_file_write_iter
: lock XFS inode XFS_IOLOCK_EXCL (on image file)
: <wait for inode to be unlocked>
:
: i.e. the kloopd, with it's split read and write work queues, has
: introduced a dependency through memory reclaim. i.e. that writes
: need to be able to progress for reads make progress.
:
: The problem, fundamentally, is that mpage_readpages() does a
: GFP_KERNEL allocation, rather than paying attention to the inode's
: mapping gfp mask, which is set to GFP_NOFS.
:
: The didn't used to happen, because the loop device used to issue
: reads through the splice path and that does:
:
: error = add_to_page_cache_lru(page, mapping, index,
: GFP_KERNEL & mapping_gfp_mask(mapping));
This has changed by commit aa4d86163e4 ("block: loop: switch to VFS
ITER_BVEC").
This patch changes mpage_readpage{s} to follow gfp mask set for the
mapping. There are, however, other places which are doing basically the
same.
lustre:ll_dir_filler is doing GFP_KERNEL from the function which
apparently uses GFP_NOFS for other allocations so let's make this
consistent.
cifs:readpages_get_pages is called from cifs_readpages and
__cifs_readpages_from_fscache called from the same path obeys mapping
gfp.
ramfs_nommu_expand_for_mapping is hardcoding GFP_KERNEL as well
regardless it uses mapping_gfp_mask for the page allocation.
ext4_mpage_readpages is the called from the page cache allocation path
same as read_pages and read_cache_pages
As I've noticed in my previous post I cannot say I would be happy about
sprinkling mapping_gfp_mask all over the place and it sounds like we
should drop gfp_mask argument altogether and use it internally in
__add_to_page_cache_locked that would require all the filesystems to use
mapping gfp consistently which I am not sure is the case here. From a
quick glance it seems that some file system use it all the time while
others are selective.

A recent change to the dst_output handling caused a new warning
when the call to NF_HOOK() is the only used of a local variable
passed as 'dev', and CONFIG_NETFILTER is disabled:
net/ipv6/ip6_output.c: In function 'ip6_output':
net/ipv6/ip6_output.c:135:21: warning: unused variable 'dev' [-Wunused-variable]
The reason for this is that the NF_HOOK macro in this case does
not reference the variable at all, and the call to dev_net(dev)
got removed from the ip6_output function. To avoid that warning now
and in the future, this changes the macro into an equivalent
inline function, which tells the compiler that the variable is
passed correctly but still unused.
The dn_forward function apparently had the same problem in
the past and added a local workaround that no longer works
with the inline function. In order to avoid a regression, we
have to also remove the #ifdef from decnet in the same patch.

We don't care if module is being unloaded anymore since hook unregister
handling will destroy queue entries using that hook.

since commit 8405a8fff3f8 ("netfilter: nf_qeueue: Drop queue entries on
nf_unregister_hook") all pending queued entries are discarded.
So we can simply remove all of the owner handling -- when module is
removed it also needs to unregister all its hooks.

This covers only the simplest case - an object size sized write, but
it's still useful in tiering setups when EC is used for the base tier
as writefull op can be proxied, saving an object promotion.
Even though updating ceph_osdc_new_request() to allow writefull should
just be a matter of fixing an assert, I didn't do it because its only
user is cephfs. All other sites were updated.
Reflects ceph.git commit 7bfb7f9025a8ee0d2305f49bf0336d2424da5b5b.

Commit 30e2bc08b2bb ("Revert "block: remove artifical max_hw_sectors
cap"") restored a clamp on max_sectors. It's now 2560 sectors instead
of 1024, but it's not good enough: we set max_hw_sectors to rbd object
size because we don't want object sized I/Os to be split, and the
default object size is 4M.
So, set max_sectors to max_hw_sectors in rbd at queue init time.

====================
mlxsw: Driver update, add initial support for Spectrum ASIC
Purpose of this patchset is to introduce initial support for Mellanox
Spectrum ASIC, including L2 bridge forwarding offload.
The only non-mlxsw patch in this patchset is the first one, introducing
pre-change upper notifier. That is used in last patch to ensure ports of
single ASIC are not bridged into multiple bridges, as that scenario is
currently not supported by driver.

Add support for new generation Mellanox Spectrum ASIC, 10/25/40/50 and
100Gb/s Ethernet Switch.
The initial driver implements bridge forwarding offload including
bridge internal VLAN support, FDB static entries, FDB learning and
HW ageing including their setup.

Since we currently do not support the offloading of 802.1D bridges, we
need to be able to let the device know it should not learn MAC addresses
on specific {Port, VID} pairs.
Add the SPVMLR register, which controls the learning enablement of
{Port, VID} pairs.

In order for a port to support {Port, VID} to FID mapping it needs to be
configured to a virtual port mode (as opposed to VLAN mode).
Add the SVPE register, which enables port virtualization.
