The current annotation is wrong as it says that we're only called
under spinlock. In fact it should be marked as under either
spinlock or RCU read lock.

Dan Carpenter reported a use before NULL check bug in the function
bucket_table_free. In fact we don't need the NULL check at all as
no caller can provide a NULL argument. So this patch fixes this by
simply removing it.

nla_memdup_cookie was overwriting err value, declared at function
scope and earlier initialized with result of ->init(). At success
nla_memdup_cookie() returns 0, and thus module refcnt decremented,
although the action was installed.

Calls made through the in-kernel interface can end up getting stuck because
of a missed variable update in a loop in rxrpc_recvmsg_data(). The problem
is like this:
(1) A new packet comes in and doesn't cause a notification to be given to
the client as there's still another packet in the ring - the
assumption being that if the client will keep drawing off data until
the ring is empty.
(2) The client is in rxrpc_recvmsg_data(), inside the big while loop that
iterates through the packets. This copies the window pointers into
variables rather than using the information in the call struct
because:
(a) MSG_PEEK might be in effect;
(b) we need a barrier after reading call->rx_top to pair with the
barrier in the softirq routine that loads the buffer.
(3) The reading of call->rx_top is done outside of the loop, and top is
never updated whilst we're in the loop. This means that even through
there's a new packet available, we don't see it and may return -EFAULT
to the caller - who will happily return to the scheduler and await the
next notification.
(4) No further notifications are forthcoming until there's an abort as the
ring isn't empty.
The fix is to move the read of call->rx_top inside the loop - but it needs
to be done before the condition is checked.

When tc actions are loaded as a module and no actions have been installed,
flushing them would result in actions removed from the memory, but modules
reference count not being decremented, so that the modules would not be
unloaded.

Commit 5e1859fbcc3c ("ipv4: ipmr: various fixes and cleanups") fixed
the issue for ipv4 ipmr:
ip_mroute_setsockopt() & ip_mroute_getsockopt() should not
access/set raw_sk(sk)->ipmr_table before making sure the socket
is a raw socket, and protocol is IGMP
The same fix should be done for ipv6 ipmr as well.
This patch can fix the panic caused by overwriting the same offset
as ipmr_table as in raw_sk(sk) when accessing other type's socket
by ip_mroute_setsockopt().

Commit b8607805dd15 ("sctp: not copying duplicate addrs to the assoc's
bind address list") tried to check for duplicate address before copying
to asoc's bind_addr list from global addr list.
But all the addrs' sin_ports in global addr list are 0 while the addrs'
sin_ports are bp->port in asoc's bind_addr list. It means even if it's
a duplicate address, af->cmp_addr will still return 0 as the their
sin_ports are different.
This patch is to fix it by setting the sin_port for addr param with
bp->port before comparing the addrs.

The cited commit makes a great job of finding optimal shift/multiplier
values assuming a 10 seconds wrap around, but forgot to change the
overflow_period computation.
It overflows in cyclecounter_cyc2ns(), and the final result is 804 ms,
which is silly.
Lets simply use 5 seconds, no need to recompute this, given how it is
supposed to work.
Later, we will use a timer instead of a work queue, since the new RX
allocation schem will no longer need mlx4_en_recover_from_oom() and the
service_task firing every 250 ms.

Bart Van Assche noted that the ib DMA mapping code was significantly

This resulted in a nice set of cleanups, but touched the entire tree

fs/ocfs2/alloc.o: warning: objtool: ocfs2_mv_path()+0x0: frame pointer state mismatch
It turns out that, for older versions of GCC, if a function has multiple
BUG() incantations, GCC will sometimes merge the corresponding
annotate_unreachable() inline asm statements into a single block. That
has the undesirable effect of removing one of the entries in the
__unreachable section, confusing objtool greatly.
A workaround for this issue is to ensure that each instance of the
inline asm statement uses a different label, so that GCC sees the
statements are unique and leaves them alone. The inline asm ‘%=’ token
could be used for that, but unfortunately older versions of GCC don't
support it. So I implemented a poor man's version of it with the
__LINE__ macro.

The Kconfig currently controlling compilation of this code is:
drivers/platform/x86/Kconfig:config INTEL_TURBO_MAX_3
drivers/platform/x86/Kconfig: bool "Intel Turbo Boost Max Technology 3.0 enumeration driver"
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.
We do uncover some implicit includes during build coverage that
were hidden behind the module.h which pulls in a lot of dependants.

There is no need to set the led_classdev's brightness value from
its set_brightness callback, this is taken care of by the led-core and
thinkpad_acpi really should not be mucking with it.

thinpad_acpi specific sysfs interface for the led, so we cannot

Some LEDs may have their brightness level changed autonomously
(outside of kernel control) by hardware / firmware. This commit
adds support for an optional brightness_hw_changed attribute to
signal such changes to userspace (if a driver can detect them):
What: /sys/class/leds/<led>/brightness_hw_changed
Date: January 2017
KernelVersion: 4.11
Description:
Last hardware set brightness level for this LED. Some LEDs
may be changed autonomously by hardware/firmware. Only LEDs
where this happens and the driver can detect this, will
have this file.
This file supports poll() to detect when the hardware
changes the brightness.
Reading this file will return the last brightness level set
by the hardware, this may be different from the current
brightness.
Drivers which want to support this, simply add LED_BRIGHT_HW_CHANGED to
their flags field and call led_classdev_notify_brightness_hw_changed()
with the hardware set brightness when they detect a hardware / firmware
triggered brightness change.

The same method to activate LM(Launch Manager) can also be used to
activate the RF Button driver with different bit toggled in the same
lm_status. To express that many functions this byte field can achieve,
rename the lm_status to app_status. And also the app_mask is the bit
mask which specifically indicate which bits are going to be changed.
This solves a problem where the AR9565 wifi included in the
Acer Aspire ES1-421 is permanently hard blocked according to the rfkill
GPIO read by ath9k.

Some Asus machines use 0x4/0x5 as their LED on/off values, while others
use 0x0/0x1, as shown in the DSDT excerpts below. Luckily it seems this
behavior is tied to different HIDs, after looking at 44 DSDTs from
different Asus models.
Another small difference is that a few of them call GWBL instead of
OWGS, and SWBL instead of OWGD. That does not seem to make a difference
for asus-wireless, and is additional reasoning to not try to call these
methods directly.

This patch adds the PCI Device id for Power Management Controller on Intel
Apollo Lake platforms.
Intel PMC IPC Driver loads as a platform driver on Apollo Lake platforms
since Intel BIOS hides the PCI Configuration space for 0:13:1 and
re-enumerates it as ACPI device (INT34D2). The correct PCI Device ID should
be added if some platform firmware choses to enumerate the device via PCI
space.

This patch adds a new API to indicate S0ix residency in usec. It utilizes
the PMC Global Control Registers (GCR) to read deep and shallow
S0ix residency.
PMC MMIO resources:
o Lower 4kB: IPC1 (PMC inter-processor communication) interface
o Upper 4kB: GCR (Global Control Registers)
This enables the power management framework to take corrective actions when
the platform fails to enter S0ix after kernel freeze as part of the suspend
to idle flow. (echo freeze > /sys/power/state).
This is expected to be used with a S0ix failsafe framework such as:

But the second check can be reduced to ".+else\s*{" and it therefore
never checked if the beginning of a line contains any other character
(like the relevant "}"). This check would also return true for "} else
{" and create warnings like
CHECK: Unbalanced braces around else statement
#391: FILE: ./net/batman-adv/tvlv.c:391:

The check can be changed to check the whole line for the missing "}" to
