    ixgbe: phy: fix uninitialized status in ixgbe_setup_phy_link_tnx
    
    Status variable is never initialized, can carry an arbitrary value
    on the stack and thus may let the function fail.

    mwifiex: simplify ad hoc join capability info
    
    While preparing an ad-hoc start command, the capability info bitmap is
    needlessly set from the command, and then the ESS bit cleared.
    
    Change to set the bitmap directly without reference to the command.

    wlcore: make wlcore_cmd_send_failsafe() static
    
    The wlcore_cmd_send_failsafe() function is only called in the cmd.c
    file, where it is definde.  Make it static.
    
    Additionally, move the EXPORT_SYMBOL macro for wl1271_cmd_send() to
    the right place.

    wlcore: check minimum buffer size in some cmd_send functions
    
    Check for the minimum required buffer length in wlcore_cmd_send() and
    wlcore_cmd_configure_failsafe.  This ensures that we will never try to
    use a buffer that is smaller than the required header.

    mwifiex: fix out of memory issue observed for USB chipsets
    
    On some platforms, system goes out of memory during heavy
    Rx traffic with our USB chipsets.
    
    In case of SDIO/PCIe, after receiving 50 packets in Rx queue
    we stop processing interrupts till packets pending fall below
    low threshold i.e 20. We don't have similar logic for USB,
    so if host platform is slow, we would hit a case where firmware
    keeps on pushing packets at high speed than driver/kernel can
    process.
    
    We will stop submitting URBs for Rx data when pending packet
    count reaches high threshold and restart them when enough
    packets are consumed to solve the problem.

    PM / Domains: Fix initial default state of the need_restore flag
    
    The initial state of the device's need_restore flag should'nt depend on
    the current state of the PM domain. For example it should be perfectly
    valid to attach an inactive device to a powered PM domain.
    
    The pm_genpd_dev_need_restore() API allow us to update the need_restore
    flag to somewhat cope with such scenarios. Typically that should have
    been done from drivers/buses ->probe() since it's those that put the
    requirements on the value of the need_restore flag.
    
    Until recently, the Exynos SOCs were the only user of the
    pm_genpd_dev_need_restore() API, though invoking it from a centralized
    location while adding devices to their PM domains.
    
    Due to that Exynos now have swithed to the generic OF-based PM domain
    look-up, it's no longer possible to invoke the API from a centralized
    location. The reason is because devices are now added to their PM
    domains during the probe sequence.
    
    Commit "ARM: exynos: Move to generic PM domain DT bindings"
    did the switch for Exynos to the generic OF-based PM domain look-up,
    but it also removed the call to pm_genpd_dev_need_restore(). This
    caused a regression for some of the Exynos drivers.
    
    To handle things more properly in the generic PM domain, let's change
    the default initial value of the need_restore flag to reflect that the
    state is unknown. As soon as some of the runtime PM callbacks gets
    invoked, update the initial value accordingly.
    
    Moreover, since the generic PM domain is verifying that all devices
    are both runtime PM enabled and suspended, using pm_runtime_suspended()
    while pm_genpd_poweroff() is invoked from the scheduled work, we can be
    sure of that the PM domain won't be powering off while having active
    devices.
    
    Do note that, the generic PM domain can still only know about active
    devices which has been activated through invoking its runtime PM resume
    callback. In other words, buses/drivers using pm_runtime_set_active()
    during ->probe() will still suffer from a race condition, potentially
    probing a device without having its PM domain being powered. That issue
    will have to be solved using a different approach.
    
    This a log from the boot regression for Exynos5, which is being fixed in
    this patch.

    ath9k: Fix RTC_DERIVED_CLK usage
    
    Based on the reference clock, which could be 25MHz or 40MHz,
    AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
    But, when a chip reset is done, processing the initvals
    sets the register back to the default value.
    
    Fix this by moving the code in ath9k_hw_init_pll() to
    ar9003_hw_override_ini(). Also, do this override for AR9531.

    When advertised capabilities are changed with mii-tool, such as:

    the existing handler has two errors.
    
    - An actual PHY register value is provided by mii-tool, and this
      must be mapped to internal state with mii_adv_to_ethtool_adv_t().
    - The PHY state machine needs to be told that autonegotiation has

    rt2x00: do not align payload on modern H/W
    
    RT2800 and newer hardware require padding between header and payload if
    header length is not multiple of 4.
    
    For historical reasons we also align payload to to 4 bytes boundary, but
    such alignment is not needed on modern H/W.
    
    Patch fixes skb_under_panic problems reported from time to time:
    
    https://bugzilla.kernel.org/show_bug.cgi?id=84911
    https://bugzilla.kernel.org/show_bug.cgi?id=72471
    http://marc.info/?l=linux-wireless&m=139108549530402&w=2
    https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591
    
    Panic happened because we eat 4 bytes of skb headroom on each
    (re)transmission when sending frame without the payload and the header
    length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
    case because paylad_aling=2 is bigger than header_align=0 we increase
    header_align by 4 bytes. To prevent that we could change the check to:
    
    	if (payload_length && payload_align > header_align)
    		header_align += 4;
    
    but not aligning payload at all is more effective and alignment is not
    really needed by H/W (that has been tested on OpenWrt project for few
    years now).

    net: sctp: fix memory leak in auth key management
    
    A very minimal and simple user space application allocating an SCTP
    socket, setting SCTP_AUTH_KEY setsockopt(2) on it and then closing
    the socket again will leak the memory containing the authentication
    key from user space:
    
    unreferenced object 0xffff8800837047c0 (size 16):
      comm "a.out", pid 2789, jiffies 4296954322 (age 192.258s)

        01 00 00 00 04 00 00 00 00 00 00 00 00 00 00 00  ................

    This is bad because of two things, we can bring down a machine from
    user space when auth_enable=1, but also we would leave security sensitive
    keying material in memory without clearing it after use. The issue is
    that sctp_auth_create_key() already sets the refcount to 1, but after
    allocation sctp_auth_set_key() does an additional refcount on it, and
    thus leaving it around when we free the socket.

    net: sctp: fix NULL pointer dereference in af->from_addr_param on malformed packet
    
    An SCTP server doing ASCONF will panic on malformed INIT ping-of-death
    in the form of:
    
      ------------ INIT[PARAM: SET_PRIMARY_IP] ------------>
    
    While the INIT chunk parameter verification dissects through many things
    in order to detect malformed input, it misses to actually check parameters
    inside of parameters. E.g. RFC5061, section 4.2.4 proposes a 'set primary
    IP address' parameter in ASCONF, which has as a subparameter an address
    parameter.
    
    So an attacker may send a parameter type other than SCTP_PARAM_IPV4_ADDRESS
    or SCTP_PARAM_IPV6_ADDRESS, param_type2af() will subsequently return 0
    and thus sctp_get_af_specific() returns NULL, too, which we then happily
    dereference unconditionally through af->from_addr_param().
    
    The trace for the log:

    A minimal way to address this is to check for NULL as we do on all

    possibly return with NULL.

    In ppp_ioctl(), bpf_prog_create() is called inside ppp_lock, which

    works around the problem by moving the allocation outside the lock.
    
    The bug was revealed by the recent change in net/core/filter.c, as it
    allocates via vmalloc() instead of kmalloc() now.

    (etc)
    
    This is due to the fact that as we turned on multiplatform
    for the Integrator, this enabled a lot of non-applicable
    CPU's to be selected for its multiplatform images, due to
    a lot of "depends on ARCH_INTEGRATOR" restrictions in
    arch/arm/mm/Kconfig for the different ARM CPU types.
    
    Fix this by restricting the CPU selections to respective
    multiplatform config, which now becomes a subset of the
    possible Integrator configurations, or alternatively the
    non-multiplatform config plus ARCH_INTEGRATOR, i.e.:
    
    if (!ARCH_MULTIPLATFORM || ARCH_MULTI_Vx) &&
       (ARCH_INTEGRATOR || ARCH_FOO ...)
    
    Since the Integrator has been converted to multiplatform,
    this will often take the short form:
    
    if (ARCH_MULTI_Vx && ARCH_INTEGRATOR)
    
    If no other non-multiplatform platforms are elegible.

    net: Convert LIMIT_NETDEBUG to net_dbg_ratelimited
    
    Use the more common dynamic_debug capable net_dbg_ratelimited
    and remove the LIMIT_NETDEBUG macro.
    
    All messages are still ratelimited.
    
    Some KERN_<LEVEL> uses are changed to KERN_DEBUG.
    
    This may have some negative impact on messages that were
    emitted at KERN_INFO that are not not enabled at all unless
    DEBUG is defined or dynamic_debug is enabled.  Even so,
    these messages are now _not_ emitted by default.
    
    This also eliminates the use of the net_msg_warn sysctl
    "/proc/sys/net/core/warnings".  For backward compatibility,
    the sysctl is not removed, but it has no function.  The extern
    declaration of net_msg_warn is removed from sock.h and made
    static in net/core/sysctl_net_core.c
    
    Miscellanea:
    
    o Update the sysctl documentation
    o Remove the embedded uses of pr_fmt
    o Coalesce format fragments
    o Realign arguments

    hwmon: (ibmpowernv) Quieten when probing finds no device
    
    Because we build kernels with drivers built in for many platforms, it's
    normal for the ibmpowernv driver to be loaded on systems that don't have
    the appropriate hardware.
    
    Currently the driver spams the log with:
    
      ibmpowernv ibmpowernv.0: Opal node 'sensors' not found
      ibmpowernv: Platfrom driver probe failed
    
    But there is no error, this machine is not a powernv and doesn't have
    the hardware. So change the sensors message to dev_dbg(), and only print
    an error about the probe failing if it's not ENODEV.
    
    Also fix the spelling of "Platfrom" and print the actual error value.

    When processing received traffic, pass CHECKSUM_COMPLETE status to the

    Although the stack expects checksum which doesn't include the pseudo

    header checksum from the checksum value provided by the HW.
    
    In the IPv6 case, we also compute/add the IP header checksum which
    is not added by the HW for such packets.

    blk-mq: use get_cpu/put_cpu instead of preempt_disable/preempt_enable
    
    blk-mq is using preempt_disable/enable in order to ensure that the
    queue runners are placed on the right CPU.  This does not work with
    the RT patches, because __blk_mq_run_hw_queue takes a non-raw
    spinlock with the preemption-disabled region.  If there is contention
    on the lock, this violates the rules for preemption-disabled regions.
    
    While this should be easily fixable within the RT patches just by doing
    migrate_disable/enable, we can do better and document _why_ this
    particular region runs with disabled preemption.  After the previous
    patch, it is trivial to switch it to get/put_cpu; the RT patches then
    can change it to get_cpu_light, which lets virtio-blk run under RT
    kernels.

    spi: spidev: Don't mangle max_speed_hz in underlying spi device
    
    Currently spidev allows callers to set the default speed by overriding the
    max_speed_hz in the underlying device. This achieves the immediate goal but
    is not what devices expect and can easily lead to userspace trying to set
    unsupported speeds and succeeding, apart from anything else drivers can't
    set a limit on the speed using max_speed_hz as they'd expect and any other
    devices on the bus will be affected.
    
    Instead store the default speed in the spidev struct and fill this in on
    each transfer.

    net: introduce SO_INCOMING_CPU
    
    Alternative to RPS/RFS is to use hardware support for multiple
    queues.
    
    Then split a set of million of sockets into worker threads, each
    one using epoll() to manage events on its own socket pool.
    
    Ideally, we want one thread per RX/TX queue/cpu, but we have no way to
    know after accept() or connect() on which queue/cpu a socket is managed.
    
    We normally use one cpu per RX queue (IRQ smp_affinity being properly
    set), so remembering on socket structure which cpu delivered last packet
    is enough to solve the problem.
    
    After accept(), connect(), or even file descriptor passing around
    processes, applications can use :
    
     int cpu;
     socklen_t len = sizeof(cpu);
    
     getsockopt(fd, SOL_SOCKET, SO_INCOMING_CPU, &cpu, &len);
    
    And use this information to put the socket into the right silo
    for optimal performance, as all networking stack should run
    on the appropriate cpu, without need to send IPI (RPS/RFS).

    tcp: move sk_mark_napi_id() at the right place
    
    sk_mark_napi_id() is used to record for a flow napi id of incoming

    We should do this only on established flows, not on listeners.
    
    This was 'working' by virtue of the socket cloning, but doing
    this on SYN packets in unecessary cache line dirtying.
    
    Even if we move sk_napi_id in the same cache line than sk_lock,
    we are working to make SYN processing lockless, so it is desirable
    to set sk_napi_id only for established flows.

    tracing: Kill tracing_{start,stop}_sched_switch_record() and tracing_sched_switch_assign_trace()
    
    tracing_{start,stop}_sched_switch_record() have no callers since
    87d80de2800d "tracing: Remove obsolete sched_switch tracer".
    
    The last caller of tracing_sched_switch_assign_trace() was removed
    by 30dbb20e68e6 "tracing: Remove boot tracer".

    ftrace: Add more information to ftrace_bug() output
    
    With the introduction of the dynamic trampolines, it is useful that if
    things go wrong that ftrace_bug() produces more information about what
    the current state is. This can help debug issues that may arise.
    
    Ftrace has lots of checks to make sure that the state of the system it
    touchs is exactly what it expects it to be. When it detects an abnormality
    it calls ftrace_bug() and disables itself to prevent any further damage.
    It is crucial that ftrace_bug() produces sufficient information that
    can be used to debug the situation.

    ftrace/x86: Allow !CONFIG_PREEMPT dynamic ops to use allocated trampolines
    
    When the static ftrace_ops (like function tracer) enables tracing, and it
    is the only callback that is referencing a function, a trampoline is
    dynamically allocated to the function that calls the callback directly
    instead of calling a loop function that iterates over all the registered
    ftrace ops (if more than one ops is registered).
    
    But when it comes to dynamically allocated ftrace_ops, where they may be
    freed, on a CONFIG_PREEMPT kernel there's no way to know when it is safe
    to free the trampoline. If a task was preempted while executing on the
    trampoline, there's currently no way to know when it will be off that
    trampoline.
    
    But this is not true when it comes to !CONFIG_PREEMPT. The current method
    of calling schedule_on_each_cpu() will force tasks off the trampoline,
    becaues they can not schedule while on it (kernel preemption is not
    configured). That means it is safe to free a dynamically allocated
    ftrace ops trampoline when CONFIG_PREEMPT is not configured.

    EDAC, pci_sysfs: remove unneccessary ifdef around entire file
    
    The file edac_pci_sysfs.c is dependent on CONFIG_PCI. This is already
    modelled in the Makefile, but edac_pci_sysfs.o is still contained in
    the list of files compiled even without CONFIG_PCI.
    
    This change removes edac_pci_sysfs.o from the list of built objects
    when not having CONFIG_PCI enabled and removes the then-unnecessary
    ifdef from the source file.

    dm thin: suspend/resume active thin devices when reloading thin-pool
    
    Before this change it was expected that userspace would first suspend
    all active thin devices, reload/resize the thin-pool target, then resume
    all active thin devices.  Now the thin-pool suspend/resume will trigger
    the suspend/resume of all active thins via appropriate calls to
    dm_internal_suspend and dm_internal_resume.
    
    Store the mapped_device for each thin device in struct thin_c to make
    these calls possible.

    ghes_edac: Use snprintf() to silence a static checker warning
    
    My static checker complains because the "e->location" has up to 256
    characters but we are copying it into the "pvt->detail_location" which
    only has space for 240 characters.  That's not counting the surrounding
    text and the "e->other_detail" string which can be over 80 characters
    long.
    
    I am not familiar with this code but presumably it normally works.
    Let's add a limit though for safety.

    dm: enhance internal suspend and resume interface
    
    Rename dm_internal_{suspend,resume} to dm_internal_{suspend,resume}_fast
    -- dm-stats will continue using these methods to avoid all the extra
    suspend/resume logic that is not needed in order to quickly flush IO.
    
    Introduce dm_internal_suspend_noflush() variant that actually calls the
    mapped_device's target callbacks -- otherwise target-specific hooks are
    avoided (e.g. dm-thin's thin_presuspend and thin_postsuspend).  Common
    code between dm_internal_{suspend_noflush,resume} and
    dm_{suspend,resume} was factored out as __dm_{suspend,resume}.
    
    Update dm_internal_{suspend_noflush,resume} to always take and release
    the mapped_device's suspend_lock.  Also update dm_{suspend,resume} to be
    aware of potential for DM_INTERNAL_SUSPEND_FLAG to be set and respond
    accordingly by interruptibly waiting for the DM_INTERNAL_SUSPEND_FLAG to
    be cleared.  Add lockdep annotation to dm_suspend() and dm_resume().
    
    Also add DM_INTERNAL_SUSPEND_FLAG to status report.  This new
    DM_INTERNAL_SUSPEND_FLAG state is being tracked/reported to assist with
    debugging (e.g. 'dmsetup info' will report an internally suspended
    device accordingly).
    
    The existing DM_SUSPEND_FLAG remains unchanged.
    DM_INTERNAL_SUSPEND_FLAG is set by dm_internal_suspend_noflush() and
    cleared by dm_internal_resume().
    
    Both DM_SUSPEND_FLAG and DM_INTERNAL_SUSPEND_FLAG may be set if a device
    was already suspended when dm_internal_suspend_noflush() was called --
    this can be thought of as a "nested suspend".  A "nested suspend" can
    with legacy userspace dm-thin code that might suspend all active thin
    volumes before suspending the pool for resize.
    
    But otherwise, in the normal dm-thin-pool suspend case moving forward:
    the thin-pool will have DM_SUSPEND_FLAG set and all active thins from
    that thin-pool will have DM_INTERNAL_SUSPEND_FLAG set.

Chapter 20: Conditional Compilation

Wherever possible, don't use preprocessor conditionals (#if, #ifdef) in .c
files; doing so makes code harder to read and logic harder to follow. Instead,
use such conditionals in a header file defining functions for use in those .c
files, providing no-op stub versions in the #else case, and then call those
functions unconditionally from .c files. The compiler will avoid generating
any code for the stub calls, producing identical results, but the logic will
remain easy to follow.

Prefer to compile out entire functions, rather than portions of functions or
portions of expressions. Rather than putting an ifdef in an expression, factor
out part or all of the expression into a separate helper function and apply the
conditional to that function.

If you have a function or variable which may potentially go unused in a
particular configuration, and the compiler would warn about its definition
going unused, mark the definition as __maybe_unused rather than wrapping it in
a preprocessor conditional. (However, if a function or variable *always* goes
unused, delete it.)

Within code, where possible, use the IS_ENABLED macro to convert a Kconfig
symbol into a C boolean expression, and use it in a normal C conditional:

if (IS_ENABLED(CONFIG_SOMETHING)) {
...
}

The compiler will constant-fold the conditional away, and include or exclude
the block of code just as with an #ifdef, so this will not add any runtime
overhead. However, this approach still allows the C compiler to see the code
inside the block, and check it for correctness (syntax, types, symbol
references, etc). Thus, you still have to use an #ifdef if the code inside the
block references symbols that will not exist if the condition is not met.

At the end of any non-trivial #if or #ifdef block (more than a few lines),
place a comment after the #endif on the same line, noting the conditional
expression used. For instance:

#ifdef CONFIG_SOMETHING
...
#endif /* CONFIG_SOMETHING */
