8336bf68b5 mmc: mxcmmc: Include interrupt.h in the platform data header
The mxcmmc platform data header depends on interrupt.h. Don't rely on the
public mmc header host.h to include it, bud instead make that dependency
explicit.

0f21c58c63 mmc: dw_mmc: Remove the public dw_mmc header file
There are currently no external users of the public dw_mmc header file,
except the dw_mmc driver itself. Therefore let's move the definitions from
the public dw_mmc header file into the existing private dw_mmc header file
and then remove the public one.

dba4bb484e mmc: sh_mmcif: Remove unused clk_ctrl2_present from the platform data
There are currently no users of the clk_ctrl2_present member from the
platform data, so let's remove it.

Note, as some of the sh_mmcif variants may support clk_ctrl2, let's keep
the current code in the driver, which deals with this. For future support,
we should invent a DT binding instead, but let's leave that until it's
needed.

====================
Netfilter updates for net-next

The following patchset contains Netfilter updates for your net-next
tree, most relevantly they are:

1) Extend nft_exthdr to allow to match TCP options bitfields, from
   Manuel Messner.

2) Allow to check if IPv6 extension header is present in nf_tables,
   from Phil Sutter.

3) Allow to set and match conntrack zone in nf_tables, patches from
   Florian Westphal.

4) Several patches for the nf_tables set infrastructure, this includes
   cleanup and preparatory patches to add the new bitmap set type.

5) Add optional ruleset generation ID check to nf_tables and allow to
   delete rules that got no public handle yet via NFTA_RULE_ID. These
   patches add the missing kernel infrastructure to support rule
   deletion by description from userspace.

6) Missing NFT_SET_OBJECT flag to select the right backend when sets
   stores an object map.

7) A couple of cleanups for the expectation and SIP helper, from Gao
   feng.

7f67763337 bpf: introduce BPF_F_ALLOW_OVERRIDE flag
If BPF_F_ALLOW_OVERRIDE flag is used in BPF_PROG_ATTACH command
to the given cgroup the descendent cgroup will be able to override
effective bpf program that was inherited from this cgroup.
By default it's not passed, therefore override is disallowed.

Examples:
1.
prog X attached to /A with default
prog Y fails to attach to /A/B and /A/B/C
Everything under /A runs prog X

2.
prog X attached to /A with allow_override.
prog Y fails to attach to /A/B with default (non-override)
prog M attached to /A/B with allow_override.
Everything under /A/B runs prog M only.

3.
prog X attached to /A with allow_override.
prog Y fails to attach to /A with default.
The user has to detach first to switch the mode.

In the future this behavior may be extended with a chain of
non-overridable programs.

Also fix the bug where detach from cgroup where nothing is attached
was not throwing error. Return ENOENT in such case.

Add several testcases and adjust libbpf.

8c4d4e8b56 netfilter: nfnetlink: allow to check for generation ID
This patch allows userspace to specify the generation ID that has been
used to build an incremental batch update.

If userspace specifies the generation ID in the batch message as
attribute, then nfnetlink compares it to the current generation ID so
you make sure that you work against the right baseline. Otherwise, bail
out with ERESTART so userspace knows that its changeset is stale and
needs to respin. Userspace can do this transparently at the cost of
taking slightly more time to refresh caches and rework the changeset.

This check is optional, if there is no NFNL_BATCH_GENID attribute in the
batch begin message, then no check is performed.

baa6d39663 fpga: Add scatterlist based programming
Requiring contiguous kernel memory is not a good idea, this is a limited

This introduces a .write_sg op that supporting drivers can provide
to DMA directly from dis-contiguous memory and a new entry point
fpga_mgr_buf_load_sg that users can call to directly provide page
lists.

The full matrix of compatibility is provided, either the linear or sg
interface can be used by the user with a driver supporting either
interface.

A notable change for drivers is that the .write op can now be called

902cc69a08 mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address op codes
This patch renames the SPINOR_OP_* macros of the 4-byte address
instruction set so the new names all share a common pattern: the 4-byte
address name is built from the 3-byte address name appending the "_4B"
suffix.

The patch also introduces new op codes to support other SPI protocols such
as SPI 1-4-4 and SPI 1-2-2.

This is a transitional patch and will help a later patch of spi-nor.c
to automate the translation from the 3-byte address op codes into their
4-byte address version.

e99ca98f1d mtd: spi-nor: Add support for S3AN spi-nor devices
Xilinx Spartan-3AN FPGAs contain an In-System Flash where they keep
their configuration data and (optionally) some user data.

The protocol of this flash follows most of the spi-nor standard. With
the following differences:

- Page size might not be a power of two.
- The address calculation (default addressing mode).
- The spi nor commands used.

Protocol is described on Xilinx User Guide UG333

39ab9555c2 iommu: Add sysfs bindings for struct iommu_device
There is currently support for iommu sysfs bindings, but
those need to be implemented in the IOMMU drivers. Add a
more generic version of this by adding a struct device to
struct iommu_device and use that for the sysfs bindings.

Also convert the AMD and Intel IOMMU driver to make use of
it.

b0119e8708 iommu: Introduce new 'struct iommu_device'
This struct represents one hardware iommu in the iommu core
code. For now it only has the iommu-ops associated with it,
but that will be extended soon.

The register/unregister interface is also added, as well as
making use of it in the Intel and AMD IOMMU drivers.

dfb4357da6 time: Remove CONFIG_TIMER_STATS
Currently CONFIG_TIMER_STATS exposes process information across namespaces:

kernel/time/timer_list.c print_timer():

        SEQ_printf(m, ", %s/%d", tmp, timer->start_pid);

/proc/timer_list:

 #11: <0000000000000000>, hrtimer_wakeup, S:01, do_nanosleep, cron/2570

Given that the tracer can give the same information, this patch entirely
removes CONFIG_TIMER_STATS.

6ce77bfd6c perf/core: Allow kernel filters on CPU events
While supporting file-based address filters for CPU events requires some
extra context switch handling, kernel address filters are easy, since the
kernel mapping is preserved across address spaces. It is also useful as
it permits tracing scheduling paths of the kernel.

This patch allows setting up kernel filters for CPU events.
