Pull x86 fixes from Thomas Gleixner:
"A small set of changes:
- a fixup for kexec related to 5-level paging mode. That covers most
of the cases except kexec from a 5-level kernel to a 4-level
kernel. The latter needs more work and is going to come in 4.17
- two trivial fixes for build warnings triggered by LTO and gcc-8"

Pull irq fixes from Thomas Gleixner:
"Two small changes:
- a fix for a interrupt regression caused by the vector management
changes in 4.15 affecting museum pieces which rely on interrupt
probing for legacy (e.g. parallel port) devices.
One of the startup calls in the autoprobe code was not changed to
the new activate_and_startup() function resulting in a warning and
as a consequence failing to discover the device interrupt.
- a trivial update to the copyright/license header of the STM32 irq
chip driver"

Pull more block updates from Jens Axboe:
"Most of this is fixes and not new code/features:
- skd fix from Arnd, fixing a build error dependent on sla allocator
type.
- blk-mq scheduler discard merging fixes, one from me and one from
Keith. This fixes a segment miscalculation for blk-mq-sched, where
we mistakenly think two segments are physically contigious even
though the request isn't carrying real data. Also fixes a bio-to-rq
merge case.
- Don't re-set a bit on the buffer_head flags, if it's already set.
This can cause scalability concerns on bigger machines and
workloads. From Kemi Wang.
- Add BLK_STS_DEV_RESOURCE return value to blk-mq, allowing us to
distuingish between a local (device related) resource starvation
and a global one. The latter might happen without IO being in
flight, so it has to be handled a bit differently. From Ming"

Update the binding documentation for APCS to mention that the APCS
hardware block also expose a clock controller functionality.
The APCS clock controller is a mux and half-integer divider. It has the
main CPU PLL as an input and provides the clock for the application CPU.

git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardened usercopy whitelisting from Kees Cook:
"Currently, hardened usercopy performs dynamic bounds checking on slab
cache objects. This is good, but still leaves a lot of kernel memory
available to be copied to/from userspace in the face of bugs.
To further restrict what memory is available for copying, this creates
a way to whitelist specific areas of a given slab cache object for
copying to/from userspace, allowing much finer granularity of access
control.
Slab caches that are never exposed to userspace can declare no
whitelist for their objects, thereby keeping them unavailable to
userspace via dynamic copy operations. (Note, an implicit form of
whitelisting is the use of constant sizes in usercopy operations and
get_user()/put_user(); these bypass all hardened usercopy checks since
these sizes cannot change at runtime.)
This new check is WARN-by-default, so any mistakes can be found over
the next several releases without breaking anyone's system.
The series has roughly the following sections:
- remove %p and improve reporting with offset
- prepare infrastructure and whitelist kmalloc
- update VFS subsystem with whitelists
- update SCSI subsystem with whitelists
- update network subsystem with whitelists
- update process memory with whitelists

When pulling the recent pinctrl merge, I was surprised by how a
pinctrl-only pull request ended up rebuilding basically the whole
kernel.
The reason for that ended up being that <linux/device.h> included
<linux/pinctrl/devinfo.h>, so any change to that file ended up causing
pretty much every driver out there to be rebuilt.
The reason for that was because 'struct device' has this in it:
#ifdef CONFIG_PINCTRL
struct dev_pin_info *pins;
#endif
but we already avoid header includes for these kinds of things in that
header file, preferring to just use a forward-declaration of the
structure instead. Exactly to avoid this kind of header dependency.
Since some drivers seem to expect that <linux/pinctrl/devinfo.h> header
to come in automatically, move the include to <linux/pinctrl/pinctrl.h>
instead. It might be better to just make the includes more targeted,
but I'm not going to review every driver.
It would definitely be good to have a tool for finding and minimizing
header dependencies automatically - or at least help with them. Right
now we almost certainly end up having way too many of these things, and
it's hard to test every single configuration.
FWIW, you can get a sense of the "hotness" of a header file with something
like this after doing a full build:
find . -name '.*.o.cmd' -print0 |
xargs -0 tail --lines=+2 |
grep -v 'wildcard ' |
tr ' \\' '\n' |
sort | uniq -c | sort -n | less -S
which isn't exact (there are other things in those '*.o.cmd' than just
the dependencies, and the "--lines=+2" only removes the header), but
might a useful approximation.
With this patch, <linux/pinctrl/devinfo.h> drops to "only" having 833
users in the current x86-64 allmodconfig. In contrast, <linux/device.h>
has 14857 build files including it directly or indirectly.
Of course, the headers that absolutely _everybody_ includes (things like
<linux/types.h> etc) get a score of 23000+.

Currently, when booting a kernel with DMI support on a platform that has
no DMI tables, the following output is emitted into the kernel log:
[ 0.128818] DMI not present or invalid.
...
[ 1.306659] dmi: Firmware registration failed.
...
[ 2.908681] dmi-sysfs: dmi entry is absent.
The first one is a pr_info(), but the subsequent ones are pr_err()s that
complain about a condition that is not really an error to begin with.
So let's clean this up, and give up silently if dma_available is not set.

The handling of empty DMI strings looks quite broken to me:
* Strings from 1 to 7 spaces are not considered empty.
* True empty DMI strings (string index set to 0) are not considered
empty, and result in allocating a 0-char string.
* Strings with invalid index also result in allocating a 0-char
string.
* Strings starting with 8 spaces are all considered empty, even if
non-space characters follow (sounds like a weird thing to do, but
I have actually seen occurrences of this in DMI tables before.)
* Strings which are considered empty are reported as 8 spaces,
instead of being actually empty.
Some of these issues are the result of an off-by-one error in memcmp,
the rest is incorrect by design.
So let's get it square: missing strings and strings made of only
spaces, regardless of their length, should be treated as empty and
no memory should be allocated for them. All other strings are
non-empty and should be allocated.

I don't think it makes sense to check for a possible bad
initialization order at run time on every system when it is all
decided at build time.
A more efficient way to make sure developers do not introduce new
calls to dmi_check_system() too early in the initialization sequence
is to simply document the expected call order. That way, developers
have a chance to get it right immediately, without having to
test-boot their kernel, wonder why it does not work, and parse the
kernel logs for a warning message. And we get rid of the run-time
performance penalty as a nice side effect.

Function dmi_matches can me made a bit faster:
* The documented purpose of dmi_initialized is to catch too early
calls to dmi_check_system(). I'm not fully convinced it justifies
slowing down the initialization of all systems out there, but at
least the check should not have been moved from dmi_check_system()
to dmi_matches(). dmi_matches() is being called for every entry of
the table passed to dmi_check_system(), causing the same redundant
check to be performed again and again. So move it back to
dmi_check_system(), reverting this specific portion of commit
d7b1956fed33 ("DMI: Introduce dmi_first_match to make the interface
more flexible").
* Don't check for the exact_match flag again when we already know its
value.

This patch effectively reverts commit 9f1c2674b328 ("net: memcontrol:
defer call to mem_cgroup_sk_alloc()").
Moving mem_cgroup_sk_alloc() to the inet_csk_accept() completely breaks
memcg socket memory accounting, as packets received before memcg
pointer initialization are not accounted and are causing refcounting
underflow on socket release.
Actually the free-after-use problem was fixed by
commit c0576e397508 ("net: call cgroup_sk_alloc() earlier in
sk_clone_lock()") for the cgroup pointer.
So, let's revert it and call mem_cgroup_sk_alloc() just before
cgroup_sk_alloc(). This is safe, as we hold a reference to the socket
we're cloning, and it holds a reference to the memcg.
Also, let's drop BUG_ON(mem_cgroup_is_root()) check from
mem_cgroup_sk_alloc(). I see no reasons why bumping the root
memcg counter is a good reason to panic, and there are no realistic
ways to hit it.

Without this fix, not only a WARN_ONCE() was issued, but we were also
leaking memory.

gcc-8 points out that the skb_copy_to_linear_data() argument points to
the skb itself, which makes it run into a problem with overlapping
memcpy arguments:
In file included from include/linux/ip.h:20,
from drivers/net/ethernet/qlogic/qlge/qlge_main.c:26:
drivers/net/ethernet/qlogic/qlge/qlge_main.c: In function 'ql_realign_skb':
include/linux/skbuff.h:3378:2: error: 'memcpy' source argument is the same as destination [-Werror=restrict]
memcpy(skb->data, from, len);
It's unclear to me what the best solution is, maybe it ought to use a
different helper that adjusts the skb data in a safe way. Simply using
memmove() here seems like the easiest workaround.

passing the strlen() of the source string as the destination
length is pointless, and gcc-8 now warns about it:

include/linux/string.h:253: error: 'strncpy' specified bound depends on the length of the source argument [-Werror=stringop-overflow=]
This changes qed_grc_dump_big_ram() to instead uses the length of
the destination buffer, and use strscpy() to guarantee nul-termination.

Building with link-time-optimizations revealed that the cxgb4 driver does
a fixed-size memcpy() from a variable-length constant string into the
network interface name:
In function 'memcpy',
inlined from 'cfg_queues_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:335:2,
inlined from 'cxgb4_register_uld.constprop' at drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:719:9:
include/linux/string.h:350:3: error: call to '__read_overflow2' declared with attribute error: detected read beyond size of object passed as 2nd parameter
__read_overflow2();
^
I can see two equally workable solutions: either we use a strncpy() instead
of the memcpy() to stop at the end of the input, or we make the source buffer
fixed length as well. This implements the latter.

The device could only check the checksum of TCP and UDP packets. Therefore,

The declaration for swsusp_arch_resume marks it as 'asmlinkage', but the
definition in x86-32 does not, and it fails to include the header with the
declaration. This leads to a warning when building with

kernel/power/power.h:108:23: error: type of 'swsusp_arch_resume' does not match original declaration [-Werror=lto-type-mismatch]

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v4.16 kernel cycle.
Like with GPIO it is actually a bit calm this time.
Core changes:
- After lengthy discussions and partly due to my ignorance, we have
merged a patch making pinctrl_force_default() and
pinctrl_force_sleep() reprogram the states into the hardware of any
hogged pins, even if they are already in the desired state.
This only apply to hogged pins since groups of pins owned by
drivers need to be managed by each driver, lest they could not do
things like runtime PM and put pins to sleeping state even if the
system as a whole is not in sleep.
New drivers:
- New driver for the Microsemi Ocelot SoC. This is used in ethernet
switches.
- The X-Powers AXP209 GPIO driver was extended to also deal with pin
control and moved over from the GPIO subsystem. This circuit is a
mixed-mode integrated circuit which is part of AllWinner designs.
- New subdriver for the Qualcomm MSM8998 SoC, core of a high end
mobile devices (phones) chipset.
- New subdriver for the ST Microelectronics STM32MP157 MPU and
STM32F769 MCU from the STM32 family.
- New subdriver for the MediaTek MT7622 SoC. This is used for
routers, repeater, gateways and such network infrastructure.
- New subdriver for the NXP (former Freescale) i.MX 6ULL. This SoC
has multimedia features and target "smart devices", I guess in-car
entertainment, in-flight entertainment, industrial control panels
etc.
General improvements:
- Incremental improvements on the SH-PFC subdrivers for things like
the CAN bus.
- Enable the glitch filter on Baytrail GPIOs used for interrupts.
- Proper handling of pins to GPIO ranges on the Semtec SX150X
- An IRQ setup ordering fix on MCP23S08.
- A good set of janitorial coding style fixes"

It's expensive to set buffer flags that are already set, because that
causes a costly cache line transition.
A common case is setting the "verified" flag during ext4 writes.
This patch checks for the flag being set first.
With the AIM7/creat-clo benchmark testing on a 48G ramdisk based-on ext4
file system, we see 3.3%(15431->15936) improvement of aim7.jobs-per-min on
a 2-sockets broadwell platform.
What the benchmark does is: it forks 3000 processes, and each process do
the following:
a) open a new file
b) close the file
c) delete the file
until loop=100*1000 times.
The original patch is contributed by Andi Kleen.

Pull clk updates from Stephen Boyd:
"The core framework has a handful of patches this time around, mostly
due to the clk rate protection support added by Jerome Brunet.
This feature will allow consumers to lock in a certain rate on the
output of a clk so that things like audio playback don't hear pops
when the clk frequency changes due to shared parent clks changing
rates. Currently the clk API doesn't guarantee the rate of a clk stays
at the rate you request after clk_set_rate() is called, so this new
API will allow drivers to express that requirement.
Beyond this, the core got some debugfs pretty printing patches and a
couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h
file causes small one-liners in all the architecture Kbuild files.
Overall, the driver diff seems to be the normal stuff that comes all
the time to fix little problems here and there and to support new
hardware.
Summary:
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs"
