net: timeout fixes for GENET and SYSTEMPORT
This patch series fixes occasional transmit timeout around the time
the system goes into suspend. GENET and SYSTEMPORT have nearly the same
logic in that regard and were both affected in the same way.
Please queue up for stable, thanks!

A timing hazard exists when the network interface is stopped that
allows a watchdog timeout to be processed by a separate core in
parallel. This creates the potential for the timeout handler to
wake the queues while the driver is shutting down, or access
registers after their clocks have been removed.
The more common case is that the watchdog timeout will produce a
warning message which doesn't lead to a crash. The chances of this
are greatly increased by the fact that bcm_sysport_netif_stop stops
the transmit queues which can easily precipitate a watchdog time-
out because of stale trans_start data in the queues.
This commit corrects the behavior by ensuring that the watchdog
timeout is disabled before enterring bcm_sysport_netif_stop. There
are currently only two users of the bcm_sysport_netif_stop function:
close and suspend.
The close case already handles the issue by exiting the RUNNING
state before invoking the driver close service.
The suspend case now performs the netif_device_detach to exit the
PRESENT state before the call to bcm_sysport_netif_stop rather than
after it.
These behaviors prevent any future scheduling of the driver timeout
service during the window. The netif_tx_stop_all_queues function
in bcm_sysport_netif_stop is replaced with netif_tx_disable to ensure
synchronization with any transmit or timeout threads that may
already be executing on other cores.
For symmetry, the netif_device_attach call upon resume is moved to
after the call to bcm_sysport_netif_start. Since it wakes the transmit
queues it is not necessary to invoke netif_tx_start_all_queues from
bcm_sysport_netif_start so it is moved into the driver open service.

If the network becomes (partially) unavailable, say by disabling IPv6, the
background ACK transmission routine can get itself into a tizzy by
proposing immediate ACK retransmission. Since we're in the call event
processor, that happens immediately without returning to the workqueue
manager.
The condition should clear after a while when either the network comes back
or the call times out.
Fix this by:
(1) When re-proposing an ACK on failed Tx, don't schedule it immediately.
This will allow a certain amount of time to elapse before we try
again.
(2) Enforce a return to the workqueue manager after a certain number of
iterations of the call processing loop.
(3) Add a backoff delay that increases the delay on deferred ACKs by a
jiffy per failed transmission to a limit of HZ. The backoff delay is
cleared on a successful return from kernel_sendmsg().
(4) Cancel calls immediately if the opening sendmsg fails. The layer
above can arrange retransmission or rotate to another server.

icmp6_send() function is expensive on systems with a large number of
interfaces. Every time it’s called, it has to verify that the source
address does not correspond to an existing anycast address by looping
through every device and every anycast address on the device. This can
result in significant delays for a CPU when there are a large number of
neighbors and ND timers are frequently timing out and calling
neigh_invalidate().
Add anycast addresses to a global hashtable to allow quick searching for
matching anycast addresses. This is based on inet6_addr_lst in addrconf.c.

There is a null check on dst_file->private data which suggests
it can be potentially null. However, before this check, pointer
smb_file_target is derived from dst_file->private and dereferenced
in the call to tlink_tcon, hence there is a potential null pointer
deference.
Fix this by assigning smb_file_target and target_tcon after the

"This series contains a number of improvements to existing drivers,

for more SoC generations. To round things off this fixes an issue with
the sysfs interface"

pwm: tegra: Remove gratuituous blank line
The Keystone QMSS driver is pretty damaged, in the sense that it
does things like this:
irq_set_affinity_hint(irq, to_cpumask(&cpu_map));
where cpu_map is a local variable. As we leave the function, this
will point to nowhere-land, and things will end-up badly.
Instead, let's use a proper cpumask that gets allocated, giving
the driver a chance to actually work with things like irqbalance
as well as have a hypothetical 64bit future.

After 'a66649dab350 arm64: fix vdso-offsets.h dependency' if
one will try to build .i file in case of external kernel module,
build fails complaining that prepare0 target is missing. This
issue came up with SystemTap when it tries to build variety
of .i files for its own generated kernel modules trying to
figure given kernel features/capabilities.
The issue is that prepare0 is defined in top level Makefile
only if KBUILD_EXTMOD is not defined. .i file rule depends
on prepare and in case KBUILD_EXTMOD defined top level Makefile
contains empty rule for prepare. But after mentioned commit
arch/arm64/Makefile would introduce dependency on prepare0
through its own prepare target.
Fix it to put proper ifdef KBUILD_EXTMOD around code introduced
by mentioned commit. It matches what top level Makefile does.

Rework the vfs_clone_file_range and vfs_dedupe_file_range infrastructure to use
a common .remap_file_range method and supply generic bounds and sanity checking
functions that are shared with the data write path. The current VFS
infrastructure has problems with rlimit, LFS file sizes, file time stamps,
maximum filesystem file sizes, stripping setuid bits, etc and so they are
addressed in these commits.
We also introduce the ability for the ->remap_file_range methods to return short
clones so that clones for vfs_copy_file_range() don't get rejected if the entire
range can't be cloned. It also allows filesystems to sliently skip deduplication
of partial EOF blocks if they are not capable of doing so without requiring
errors to be thrown to userspace.
All existing filesystems are converted to user the new .remap_file_range method,
and both XFS and ocfs2 are modified to make use of the new generic checking
infrastructure.
