Pull RCU updates from Ingo Molnar:
"The sole purpose of these changes is to shrink and simplify the RCU
code base, which has suffered from creeping bloat over the past couple
of years. The end result is a net removal of ~2700 lines of code:
79 files changed, 1496 insertions(+), 4211 deletions(-)
Plus there's a marked reduction in the Kconfig space complexity as
well, here's the number of matches on 'grep RCU' in the .config:
before after
x86-defconfig 17 15
x86-allmodconfig 33 20"

Pull objtool updates from Ingo Molnar:
"This is an extensive rewrite of the objdump tool to track all stack
pointer modifications through the machine instructions of disassembled
functions found in kernel .o files.
This re-design removes the prior dependency on CONFIG_FRAME_POINTERS,
with the goal to prepare the tool to generate kernel debuginfo data in
the future. There's also an increase in checking/tracking robustness
as a side effect as well.
No (intended) changes to existing functionality"

Pull core block/IO updates from Jens Axboe:
"This is the main pull request for the block layer for 4.13. Not a huge
round in terms of features, but there's a lot of churn related to some
core cleanups.
Note this depends on the UUID tree pull request, that Christoph
already sent out.
This pull request contains:
- A series from Christoph, unifying the error/stats codes in the
block layer. We now use blk_status_t everywhere, instead of using
different schemes for different places.
- Also from Christoph, some cleanups around request allocation and IO
scheduler interactions in blk-mq.
- And yet another series from Christoph, cleaning up how we handle
and do bounce buffering in the block layer.
- A blk-mq debugfs series from Bart, further improving on the support
we have for exporting internal information to aid debugging IO
hangs or stalls.
- Also from Bart, a series that cleans up the request initialization
differences across types of devices.
- A series from Goldwyn Rodrigues, allowing the block layer to return
failure if we will block and the user asked for non-blocking.
- Patch from Hannes for supporting setting loop devices block size to
that of the underlying device.
- Two series of patches from Javier, fixing various issues with
lightnvm, particular around pblk.
- A series from me, adding support for write hints. This comes with
NVMe support as well, so applications can help guide data placement
on flash to improve performance, latencies, and write
amplification.
- A series from Ming, improving and hardening blk-mq support for
stopping/starting and quiescing hardware queues.
- Two pull requests for NVMe updates. Nothing major on the feature
side, but lots of cleanups and bug fixes. From the usual crew.
- A series from Neil Brown, greatly improving the bio rescue set
support. Most notably, this kills the bio rescue work queues, if we
don't really need them.
- Lots of other little bug fixes that are all over the place"

Pull uuid subsystem from Christoph Hellwig:
"This is the new uuid subsystem, in which Amir, Andy and I have started
consolidating our uuid/guid helpers and improving the types used for
them. Note that various other subsystems have pulled in this tree, so
I'd like it to go in early.
UUID/GUID summary:
- introduce the new uuid_t/guid_t types that are going to replace the
somewhat confusing uuid_be/uuid_le types and make the terminology
fit the various specs, as well as the userspace libuuid library.
(me, based on a previous version from Amir)
- consolidated generic uuid/guid helper functions lifted from XFS and
libnvdimm (Amir and me)
- conversions to the new types and helpers (Amir, Andy and me)"

DMA_ERROR_CODE for DMA API calls, if device isn't capable of DMA

Contrary to popular belief, PPIs connected to a GICv3 to not have
an affinity field similar to that of GICv2. That is consistent
with the fact that GICv3 is designed to accomodate thousands of
CPUs, and fitting them as a bitmap in a byte is... difficult.

Major changes:
iwlwifi
* some important fixes for 9000 HW
* support for version 30 of the FW API for 8000 and 9000 series
* a few new PCI IDs for 9000 series
* reorganization of common files
brcmfmac
* support 4-way handshake offloading for WPA/WPA2-PSK and 802.1X

commit 9256645af098 ("net/core: relax BUILD_BUG_ON in
netdev_stats_to_stats64") made an attempt to read beyond
the size of the source a possibility.
Fix to only copy src size to dest. As dest might be bigger than src.

It's not a good idea to add the same hlist_node to two different hash lists.
This leads to various hard to debug memory corruptions.

If mlx5 is set to be built-in and mlxfw as a module, we
get a link error:
drivers/built-in.o: In function `mlx5_firmware_flash':
(.text+0x5aed72): undefined reference to `mlxfw_firmware_flash'
Since we don't want to mandate selecting mlxfw for mlx5 users, we
use the IS_REACHABLE macro to make sure that a stub is exposed
to the caller.
