Speedy join only works when the received packet is either broadcast or an
4addr unicast packet. Thus packets converted from broadcast to unicast via
the gateway handling code have to be converted to 4addr packets to allow
the receiving gateway server to add the sender address as temporary entry
to the translation table.
Not doing it will make the batman-adv gateway server drop the DHCP response
in many situations because it doesn't yet have the TT entry for the
destination of the DHCP response.

free_percpu(rt->rt6i_pcpu) used to always happen in ip6_dst_destroy().
However, after fixing a deadlock bug in
commit 9c7370a166 ("ipv6: Fix a potential deadlock when creating pcpu rt"),
free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL.
It is worth to note that rt6i_pcpu is protected by table->tb6_lock.
kmemleak somehow did not report it. We nailed it down by
observing the pcpu entries in /proc/vmallocinfo (first suggested
by Hannes, thanks!).

There is a lock order issue in acpi_load_tables(). The namespace lock
is held before holding the interpreter lock.
With ACPI_MUTEX_DEBUG enabled in the kernel, this is printed to the
log during boot:
[ 0.885699] ACPI Error: Invalid acquire order: Thread 405884224 owns [ACPI_MTX_Namespace], wants [ACPI_MTX_Interpreter] (20160422/utmutex-263)

[ 0.893846] ACPI Error: Mutex [0x0] is not acquired, cannot release (20160422/utmutex-326)
[ 0.894019] ACPI Error: Could not release AML Interpreter mutex (20160422/exutils-133)
The issue has been introduced by the following commit:
Commit: 2f38b1b16d
ACPICA Commit: bfe03ffcde8ed56a7eae38ea0b188aeb12f9c52e
Subject: ACPICA: Namespace: Fix a regression that MLC support triggers
dead lock in dynamic table loading
Which fixed a deadlock issue for acpi_ns_load_table() in
acpi_ex_add_table() but didn't take care of the lock order in
acpi_ns_load_table() correctly.
Originally (before the above commit), ACPICA used the
namespace/interpreter locks in the following 2 key code
paths:
1. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
2. Object evaluation:
acpi_ns_evaluate
L(Interpreter)
acpi_ps_execute_method
U(Interpreter)
acpi_ns_load_table
L(Namespace)
U(Namespace)
acpi_ev_initialize_region
L(Namespace)
U(Namespace)
address_space.setup
L(Namespace)
U(Namespace)
address_space.handler
L(Namespace)
U(Namespace)
acpi_os_wait_semaphore
acpi_os_acquire_mutex
acpi_os_sleep
L(Interpreter)
U(Interpreter)
During runtime, while acpi_ns_evaluate is called, the lock order is
always Interpreter -> Namespace.
In turn, the problematic commit acquires the locks in the following
order:
3. Table loading:
acpi_ns_load_table
L(Namespace)
acpi_ns_parse_table
L(Interpreter)
acpi_ns_one_complete_parse
U(Interpreter)
U(Namespace)
To fix the lock order issue, move the interpreter lock to
acpi_ns_load_table() to ensure the lock order correctness:
4. Table loading:
acpi_ns_load_table
L(Interpreter)
L(Namespace)
acpi_ns_parse_table
acpi_ns_one_complete_parse
U(Namespace)
U(Interpreter)
However, this doesn't fix the current design issues related to the
namespace lock. For example, we can notice that in acpi_ns_evaluate(),
outside of acpi_ns_load_table(), the namespace objects may be created
by the named object creation control methods. And the creation of
the method-owned namespace objects are not locked by the namespace
lock. This patch doesn't try to fix such kind of existing issues.

Currently, link notifications are not sent by
bond_set_slave_link_state() upon enslavement if
the slave is enslaved when up.
This happens because slave->link default init value
is 0, which is the same as BOND_LINK_UP, resulting
in bond_set_slave_link_state() ignoring this transition.
This patch sets the default value of slave->link to
BOND_LINK_NOCHANGE, assuring it will count as a state
transition and thus trigger notification logic.

during the device probe. Although the probe error path was updated to
disable the clock on probe failure, there is one place after calling
tegra_i2c_init() where the clock will not be disabled on failure. Correct
the error path so that the 'div_clk' is disabled if calling
tegra_i2c_init() fails.

When mapping an interrupt to a VP(E) we must use the identifier for the
VP that the hardware expects, and this does not always match up with the
Linux CPU number. Commit d46812bb0b ("irqchip: mips-gic: Use HW IDs
for VPE_OTHER_ADDR") corrected this for the cases that existed at the
time it was written, but commit 2af70a9620 ("irqchip/mips-gic: Add a
IPI hierarchy domain") added another case before the former patch was
merged. This leads to incorrectly using Linux CPU numbers when mapping
interrupts to VPs, which breaks on certain systems such as those with
multi-core I6400 CPUs. Fix by adding the appropriate call to
mips_cm_vp_id() to retrieve the expected VP identifier.

The replacement of last_bonding_candidate in batadv_orig_node has to be an
atomic operation. Otherwise it is possible that the reference counter of a
batadv_orig_ifinfo is reduced which was no longer the
last_bonding_candidate when the new candidate is added. This can either
lead to an invalid memory access or to reference leaks which make it
impossible to an interface which was added to batman-adv.

The pointer batadv_bla_claim::backbone_gw can be changed at any time.
Therefore, access to it must be protected to ensure that two function
accessing the same backbone_gw are actually accessing the same. This is
especially important when the crc_lock is used or when the backbone_gw of a
claim is exchanged.
Not doing so leads to invalid memory access and/or reference leaks.

Several Lenovo users have reported problems with their Sierra
Wireless EM7455 modem. The driver has loaded successfully and
the MBIM management channel has appeared to work, including
establishing a connection to the mobile network. But no frames
have been received over the data interface.
The problem affects all EM7455 and MC7455, and is assumed to
affect other modems based on the same Qualcomm chipset and
baseband firmware.
Testing narrowed the problem down to what seems to be a
firmware timing bug during initialization. Adding a short sleep
while probing is sufficient to make the problem disappear.
Experiments have shown that 1-2 ms is too little to have any
effect, while 10-20 ms is enough to reliably succeed.

This reverts commit 923b93e451.
Make sure consumers do not overwrite gpio flags for pins that have
already been claimed.
While adding support for gpio drivers to refuse a request using
unsupported flags, the order of when the requested flag was checked and
the new flags were applied was reversed to that consumers could
overwrite flags for already requested gpios.
This not only affects device-tree setups where two drivers could request
the same gpio using conflicting configurations, but also allowed user
space to clear gpio flags for already claimed pins simply by attempting
to export them through the sysfs interface. By for example clearing the
FLAG_ACTIVE_LOW flag this way, user space could effectively change the
polarity of a signal.
Reverting this change obviously prevents gpio drivers from doing sanity
checks on the flags in their request callbacks. Fortunately only one
recently added driver (gpio-tps65218 in v4.6) appears to do this, and a
follow up patch could restore this functionality through a different
interface.

This fixes the issue descirbe in bug 117531
(https://bugzilla.kernel.org/show_bug.cgi?id=117531).
It's a regression introduced in linux 4.5 that causes a Oops at load of
gpio_sch and prevents powering off the computer.
The issue is that sch_gpio_reg_set is called in sch_gpio_probe before
gpio_chip data is initialized with the pointer to the sch_gpio struct. As
sch_gpio_reg_set calls gpiochip_get_data, it returns NULL which causes
the Oops.
The patch follows Mika's advice (https://lkml.org/lkml/2016/5/9/61) and
consists in modifying sch_gpio_reg_get and sch_gpio_reg_set to take a
sch_gpio struct directly instead of a gpio_chip, which avoids the call to
gpiochip_get_data.
Thanks Mika for your patience with me :-)

Right now when a new overlay inode is created, we initialize overlay
inode's ->i_mode from underlying inode ->i_mode but we retain only
file type bits (S_IFMT) and discard permission bits.
This patch changes it and retains permission bits too. This should allow
overlay to do permission checks on overlay inode itself in task context.
[SzM] It also fixes clearing suid/sgid bits on write.
