Removing couple of duplicate includes, found by "make includecheck".
That leaves 1 duplicate include in arch/s390/kernel/entry.S, which is
there for a reason (it includes generated asm/syscall_table.h twice).

sclp_early_printk could be used before .bss section is zeroed
(i.e. from als.c during the decompressor phase), therefore values used
by sclp_early_printk should be located in the .data section.
Another reason for that is to avoid potential initrd corruption, if some
code in future would use sclp_early_printk before initrd is moved from
possibly overlapping with .bss section region to a safe location.

Pull SCSI fixes from James Bottomley:
"This is a set of minor (and safe changes) that didn't make the initial
pull request plus some bug fixes.
The status handling code is actually a running regression from the
previous merge window which had an incomplete fix (now reverted) and
most of the remaining bug fixes are for problems older than the
current merge window"
[ Side note: this merge also takes the base kernel git repository to 6+
million objects for the first time. Technically we hit it a couple of
merges ago already if you count all the tag objects, but now it
reaches 6M+ objects reachable from HEAD.
I was joking around that that's when I should switch to 5.0, because
3.0 happened at the 2M mark, and 4.0 happened at 4M objects. But
probably not, even if numerology is about as good a reason as any.

A misconfigured system (e.g. with all interrupts affinitised to all CPUs)
may produce a storm of ARFS steering events. With the existing sfc ARFS
implementation, that could create a backlog of workitems that grinds the
system to a halt. To prevent this, limit the number of workitems that
may be in flight for a given SFC device to 8 (EFX_RPS_MAX_IN_FLIGHT), and
return EBUSY from our ndo_rx_flow_steer method if the limit is reached.
Given this limit, also store the workitems in an array of slots within the
struct efx_nic, rather than dynamically allocating for each request.
The limit should not negatively impact performance, because it is only
likely to be hit in cases where ARFS will be ineffective anyway.

When we inserted an ARFS filter for ndo_rx_flow_steer(), we didn't know
what the filter ID would be, so we just returned 0. Thus, we must also
pass 0 as the filter ID when calling rps_may_expire_flow() for it, and
rely on the flow_id to identify what we're talking about.

Until the primary_crng is fully initialized, don't initialize the NUMA
crng nodes. Otherwise users of /dev/urandom on NUMA systems before
the CRNG is fully initialized can get very bad quality randomness. Of
course everyone should move to getrandom(2) where this won't be an
issue, but there's a lot of legacy code out there. This related to
CVE-2018-1108.

add_device_randomness() use of crng_fast_load() was highly
problematic. Some callers of add_device_randomness() can pass in a
large amount of static information. This would immediately promote
the crng_init state from 0 to 1, without really doing much to
initialize the primary_crng's internal state with something even
vaguely unpredictable.
Since we don't have the speed constraints of add_interrupt_randomness(),
we can do a better job mixing in the what unpredictability a device
driver or architecture maintainer might see fit to give us, and do it
in a way which does not bump the crng_init_cnt variable.
Also, since add_device_randomness() doesn't bump any entropy
accounting in crng_init state 0, mix the device randomness into the
input_pool entropy pool as well. This is related to CVE-2018-1108.

The crng_init variable has three states:
0: The CRNG is not initialized at all
1: The CRNG has a small amount of entropy, hopefully good enough for
early-boot, non-cryptographical use cases
2: The CRNG is fully initialized and we are sure it is safe for
cryptographic use cases.
The crng_ready() function should only return true once we are in the
last state. This addresses CVE-2018-1108.

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"The large diff this time around is from the addition of a new clk
driver for the TI Davinci family of SoCs. So far those clks have been
supported with a custom implementation of the clk API in the arch port
instead of in the CCF. With this driver merged we're one step closer
to having a single clk API implementation.
The other large diff is from the Amlogic clk driver that underwent
some major surgery to use regmap. Beyond that, the biggest hitter is
Samsung which needed some reworks to properly handle clk provider
power domains and a bunch of PLL rate updates.
The core framework was fairly quiet this round, just getting some
cleanups and small fixes for some of the more esoteric features. And
the usual set of driver non-critical fixes, cleanups, and minor
additions are here as well.
Core:
- Rejig clk_ops::init() to be a little earlier for phase/accuracy ops
- debugfs ops macroized to shave some lines of boilerplate code
- Always calculate the phase instead of caching it in clk_get_phase()
- More __must_check on bulk clk APIs
New Drivers:
- TI's Davinci family of SoCs
- Intel's Stratix10 SoC
- stm32mp157 SoC
- Allwinner H6 CCU
- Silicon Labs SI544 clock generator chip
- Renesas R-Car M3-N and V3H SoCs
- i.MX6SLL SoCs
Removed Drivers:
- ST-Ericsson AB8540/9540
Updates:
- Mediatek MT2701 and MT7622 audsys support and MT2712 updates
- STM32F469 DSI and STM32F769 sdmmc2 support
- GPIO clks can sleep now
- Spreadtrum SC9860 RTC clks
- Nvidia Tegra MBIST workarounds and various minor fixes
- Rockchip phase handling fixes and a memory leak plugged
- Renesas drivers switch to readl/writel from clk_readl/clk_writel
- Renesas gained CPU (Z/Z2) and watchdog support
- Rockchip rk3328 display clks and rk3399 1.6GHz PLL support
- Qualcomm PM8921 PMIC XO buffers

The test which ensures that the DMI type 1 structure is long enough

The DSA stack passes received PTP frames to this driver via
mv88e6xxx_port_rxtstamp() for deferred delivery. The driver then
queues the frame and kicks the worker thread. The work callback reads
out the latched receive time stamp and then works through the queue,
delivering any non-matching frames without a time stamp.
If a new frame arrives after the worker thread has read out the time
stamp register but enters the queue before the worker finishes
processing the queue, that frame will be delivered without a time
stamp.
This patch fixes the race by moving the queue onto a list on the stack
before reading out the latched time stamp value.

Introduce a second skb list for handling control messages and limit the
number of allowed messages. Some control messages are considered more
crucial than others, resulting in the need for a second skb list. By
splitting the list into a separate high and low priority list we can
ensure that messages on the high list get added to the head of the list
that gets processed, this however has no functional impact. Previously
there was no limit on the number of messages allowed on the queue, this
could result in the queue growing boundlessly and eventually the host
running out of memory.

We currently allow signals to interrupt the wait for management FW
commands. Exiting the wait should not cause trouble, the FW will
just finish executing the command in the background and new commands
will wait for the old one to finish.
However, this may not be what users expect (Ctrl-C not actually stopping
the command). Moreover some systems routinely request link information
with signals pending (Ubuntu 14.04 runs a landscape-sysinfo python tool
from MOTD) worrying users with errors like these:
nfp 0000:04:00.0: nfp_nsp: Error -512 waiting for code 0x0007 to start
nfp 0000:04:00.0: nfp: reading port table failed -512
Make the wait for management FW responses non-interruptible.

There is a bug in handling the possible return codes from sending the
login CRQ. The current code treats any non-success return value,
minus failure to send the crq and a timeout waiting for a login response,
as a need to re-send the login CRQ. This can put the drive in an
infinite loop of trying to login when getting return values other
that a partial success such as a return code of aborted. For these
scenarios the login will not ever succeed at this point and the
driver would need to be reset again.
To resolve this loop trying to login is updated to only retry the
login if the driver gets a return code of a partial success. Other
return codes are treated as an error and the driver returns an error
from ibmvnic_login().
To avoid infinite looping in the partial success return cases, the
number of retries is capped at the maximum number of supported
queues. This value was chosen because the driver does a renegotiation
of capabilities which sets the number of queues possible and allows
the driver to attempt a login for possible value for the number
of queues supported.

The "name" field of struct vnic_login_client_data is a char array of

it's a single character). This was noticed while trying to tighten the

Hardware understands the regamma LUT as a piecewise linear function,
with points spaced exponentially along the range. We previously
programmed the LUT for range [2^-10, 2^0). This causes (normalized)
color values of 1 (=2^0) to miss the programmed LUT, and fall onto the
end region.
For DCE, the end region is extrapolated using a single (base, slope)
pair, using the max y-value from the last point in the curve as base.
This presents a problem, since this value affects all three color
channels. Scaling down the intensity of say - the blue regamma curve -
will not affect it's end region. This is especially noticiable when
using RedShift. It scales down the blue and green channels, but leaves
full-intensity colors unshifted.
Therefore, extend the range to cover [2^-10, 2^1) by programming another
hardware segment, containing only one point. That way, we won't be
hitting the end region.
Note that things are a bit different for DCN, since the end region can
be set per-channel.
