5ab356626f Pin control bulk changes for the v4.11 kernel cycle:
Core changes:
 
 - Switch the generic pin config argument from 16 to 24 bits,
   only use 8 bits for the configuration type. We might need to
   encode more information about a certain setting than we need
   to encode different generic settings.
 
 - Add a cross-talk API to the pin control GPIO back-end,
   utilizing pinctrl_gpio_set_config() from GPIO drivers that
   want to set up a certain pin configuration in the back-end.
   This also includes the .set_config() refactoring of the
   GPIO chips, so that they pass a generic configuration for
   things like debouncing and single ended (typically open
   drain). This change has also been merged in an immutable
   branch to the GPIO tree.
 
 - Take hogs with a delayed work, so that we finalize probing
   a pin controller before trying to get any hogs.
 
 - For pin controllers putting all group and function definitions
   into the device tree, we now have generic code to deal with
   this and it is used in two drivers so far.
 
 - Simplifications of the pin request conflict check.
 
 - Make dt_free_map() optional.
 
 Updates to drivers:
 
 - pinctrl-single now use the generic helpers to generate dynamic
   group and function tables from the device tree.
 
 - Texas Instruments IOdelay configuration driver add-on to
   pinctrl-single.
 
 - i.MX: use radix trees to store groups and functions, use the new
   generic group and function helpers to manage them.
 
 - Intel: add support for hardware debouncing and 1K pull-down.
   New subdriver for the Gemini Lake SoC.
 
 - Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
   MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
 
 - Aspeed: use syscon cross-dependencies to set up related bits in
   the LPC host controller and display controller.
 
 - Aspeed: finalize G4 and G5 support. Fix mux configuration on
   GPIOs. Add banks Y, Z, AA, AB and AC.
 
 - AMD: support additional GPIO.
 
 - STM32: set this controller to strict muxing mode.
   STM32H743 MCU support.
 
 - Allwinner sunxi: deep simplifications on how to support
   subvariants of SoCs without adding to much SoC-specific data
   for each subvariant, especially for sun5i variants. New driver
   for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
   variants with the new variant framework.
 
 - Mvebu: simplifications to use a MMIO and regmap abstraction.
   New subdrivers for the 98DX3236, 98DX5241 SoCs.
 
 - Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
   SoC driver to access regmaps. Add infrastructure for pin-bank
   retention control. Clean out the pin retention control from
   arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
   in the Samsung pin control driver(s).
 
 - Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
 
 - Qualcomm: use raw spinlock variants: this makes the qualcomm
   driver realtime-safe.

2fa299a917 HID: rmi: fallback to generic/multitouch if hid-rmi is not built
Commit 279967a65b ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
unconditionally switches over handling of all Synaptics touchpads to hid-rmi
(to make use of extended features of the HW); in case CONFIG_HID_RMI is
disabled though this renders the touchpad unusable, as the

	HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)

match doesn't exist and generic/multitouch doesn't bind to it either (due
to hid group mismatch).

Fix this by switching over to hid-rmi only if it has been actually built.

Merge tag 'extable-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux

Pull exception table module split from Paul Gortmaker:
 "Final extable.h related changes.

  This completes the separation of exception table content from the
  module.h header file. This is achieved with the final commit that
  removes the one line back compatible change that sourced extable.h
  into the module.h file.

  The commits are unchanged since January, with the exception of a
  couple Acks that came in for the last two commits a bit later. The
  changes have been in linux-next for quite some time[1] and have got
  widespread arch coverage via toolchains I have and also from
  additional ones the kbuild bot has.

  Maintaners of the various arch were Cc'd during the postings to
  lkml[2] and informed that the intention was to take the remaining arch
  specific changes and lump them together with the final two non-arch
  specific changes and submit for this merge window.

  The ia64 diffstat stands out and probably warrants a mention. In an
  earlier review, Al Viro made a valid comment that the original header
  separation of content left something to be desired, and that it get
  fixed as a part of this change, hence the larger diffstat"

 "The audit changes for v4.11 are relatively small compared to what we
  did for v4.10, both in terms of size and impact.

   - two patches from Steve tweak the formatting for some of the audit

   - three patches from Richard record the name of a module on module
     load, fix the logging of sockaddr information when using
     socketcall() on 32-bit systems, and add the ability to reset
     audit's lost record counter.

   - my lone patch just fixes an annoying style nit that I was reminded
     about by one of Richard's patches.

005c3490e9 Revert "ath10k: Search SMBIOS for OEM board file extension"
This reverts commit f2593cb1b2.

Paul reported that this patch with older board-2.bin ath10k initialisation
fails on Dell XPS 13:

ath10k_pci 0000:3a:00.0: failed to fetch board data for bus=pci,vendor=168c,
device=003e,subsystem-vendor=1a56,subsystem-device=1535,variant=RV_0520 from
ath10k/QCA6174/hw3.0/board-2.bin

The reason is that the older board-2.bin does not have the variant version of
the image name and ath10k does not fallback to the older naming scheme.

7a771ceac7 - Fix dm-raid transient device failure processing and other smaller
tweaks.
 
 - Add journal support to the DM raid target to close the 'write hole' on
   raid 4/5/6.
 
 - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB.
 
 - Add 'metadata2' feature to dm-cache to separate the dirty bitset out
   from other cache metadata.  This improves speed of shutting down
   a large cache device (which implies writing out dirty bits).
 
 - Fix a memory leak during dm-stats data structure destruction.
 
 - Fix a DM multipath round-robin path selector performance regression
   that was caused by less precise balancing across all paths.
 
 - Lastly, introduce a DM core fix for a long-standing DM snapshot
   deadlock that is rooted in the complexity of the device stack used in
   conjunction with block core maintaining bios on current->bio_list to
   manage recursion in generic_make_request().  A more comprehensive fix
   to block core (and its hook in the cpu scheduler) would be wonderful
   but this DM-specific fix is pragmatic considering how difficult it has
   been to make progress on a generic fix.

4c5d7bc637 usercopy: Add tests for all get_user() sizes
The existing test was only exercising native unsigned long size
get_user(). For completeness, we should check all sizes. But we
must skip some 32-bit architectures that don't implement a 64-bit
get_user().

These new tests actually uncovered a bug in ARM's 64-bit get_user()
zeroing.

Merge tag 'for-4.11/linus-merge-signed' of git://git.kernel.dk/linux-block

Pull block layer updates from Jens Axboe:

 - blk-mq scheduling framework from me and Omar, with a port of the
   deadline scheduler for this framework. A port of BFQ from Paolo is in
   the works, and should be ready for 4.12.

 - Various fixups and improvements to the above scheduling framework
   from Omar, Paolo, Bart, me, others.

 - Cleanup of the exported sysfs blk-mq data into debugfs, from Omar.
   This allows us to export more information that helps debug hangs or
   performance issues, without cluttering or abusing the sysfs API.

 - Fixes for the sbitmap code, the scalable bitmap code that was
   migrated from blk-mq, from Omar.

 - Removal of the BLOCK_PC support in struct request, and refactoring of
   carrying SCSI payloads in the block layer. This cleans up the code
   nicely, and enables us to kill the SCSI specific parts of struct
   request, shrinking it down nicely. From Christoph mainly, with help
   from Hannes.

 - Support for ranged discard requests and discard merging, also from
   Christoph.

 - Support for OPAL in the block layer, and for NVMe as well. Mainly
   from Scott Bauer, with fixes/updates from various others folks.

 - Error code fixup for gdrom from Christophe.

 - cciss pci irq allocation cleanup from Christoph.

 - Making the cdrom device operations read only, from Kees Cook.

 - Fixes for duplicate bdi registrations and bdi/queue life time
   problems from Jan and Dan.

 - Set of fixes and updates for lightnvm, from Matias and Javier.

 - A few fixes for nbd from Josef, using idr to name devices and a
   workqueue deadlock fix on receive. Also marks Josef as the current
   maintainer of nbd.

 - Fix from Josef, overwriting queue settings when the number of
   hardware queues is updated for a blk-mq device.

 - NVMe fix from Keith, ensuring that we don't repeatedly mark and IO
   aborted, if we didn't end up aborting it.

 - SG gap merging fix from Ming Lei for block.

 - Loop fix also from Ming, fixing a race and crash between setting loop
   status and IO.

 - Two block race fixes from Tahsin, fixing request list iteration and
   fixing a race between device registration and udev device add
   notifiations.

 - Double free fix from cgroup writeback, from Tejun.

 - Another double free fix in blkcg, from Hou Tao.

 - Partition overflow fix for EFI from Alden Tondettar.

fd4a61e08a sched/core: Fix build paravirt build on arm and arm64
Commit 004172bdad ("sched/core: Remove unnecessary #include headers")
removed the inclusion of asm/paravirt.h which is used to get
declarations of paravirt_steal_rq_enabled and paravirt_steal_clock.

It is implicitly included on x86 but not on arm and arm64 breaking the
build if paravirtualization is used.  Since things from that header are
used directly fix the build by putting the direct inclusion back.

e623a9e9de net: socket: fix recvmmsg not returning error from sock_error
Commit 34b88a68f2 ("net: Fix use after free in the recvmmsg exit path"),
changed the exit path of recvmmsg to always return the datagrams
variable and modified the error paths to set the variable to the error
code returned by recvmsg if necessary.

However in the case sock_error returned an error, the error code was
then ignored, and recvmmsg returned 0.

Change the error path of recvmmsg to correctly return the error code
of sock_error.

The bug was triggered by using recvmmsg on a CAN interface which was
not up. Linux 4.6 and later return 0 in this case while earlier
releases returned -ENETDOWN.

9d876e79df bpf: fix unlocking of jited image when module ronx not set
Eric and Willem reported that they recently saw random crashes when
JIT was in use and bisected this to 74451e66d5 ("bpf: make jited
programs visible in traces"). Issue was that the consolidation part
added bpf_jit_binary_unlock_ro() that would unlock previously made
read-only memory back to read-write. However, DEBUG_SET_MODULE_RONX
cannot be used for this to test for presence of set_memory_*()
functions. We need to use ARCH_HAS_SET_MEMORY instead to fix this;
also add the corresponding bpf_jit_binary_lock_ro() to filter.h.

d2852a2240 arch: add ARCH_HAS_SET_MEMORY config
Currently, there's no good way to test for the presence of
set_memory_ro/rw/x/nx() helpers implemented by archs such as
x86, arm, arm64 and s390.

There's DEBUG_SET_MODULE_RONX and DEBUG_RODATA, however both
don't really reflect that: set_memory_*() are also available
even when DEBUG_SET_MODULE_RONX is turned off, and DEBUG_RODATA
is set by parisc, but doesn't implement above functions. Thus,
add ARCH_HAS_SET_MEMORY that is selected by mentioned archs,
where generic code can test against this.

This also allows later on to move DEBUG_SET_MODULE_RONX out of
the arch specific Kconfig to define it only once depending on
ARCH_HAS_SET_MEMORY.

====================
net: mvpp2: misc improvements and preparation patches

This series contains a number of fixes, misc improvements and
preparation patches for an upcoming series that adds support for the
new PPv2.2 network controller to the mvpp2 driver.

The most significant improvements are:

 - Switching to using build_skb(), which is necessary for the upcoming
   PPv2.2 support, but anyway a good improvement to the current mvpp2
   driver (supporting PPv2.1).

 - Making the driver build on 64-bit platforms.

Changes since v3:

 - Addition of a patch "net: mvpp2: fix DMA address calculation in
   mvpp2_txq_inc_put()", which fixes a bug in the driver in the
   calculation of DMA addresses. This bug was found using
   DMA_API_DEBUG.

 - Modify the "net: mvpp2: switch to build_skb() in the RX path" patch
   to recalculate the fragment size when the MTU is changed in
   mvpp2_bm_update_mtu().

 - Added Acked-by from Russell King on all patches, except:

    * "net: mvpp2: fix DMA address calculation in
      mvpp2_txq_inc_put()", because it's a new patch

    * "net: mvpp2: switch to build_skb() in the RX path" because I
      modified it since the v3.

 - Rebased on top of 4.10.

Changes since v2:

 - Fix remaining 64-bit build warning, reported by David Miller.

 - Adjust how bit mask related definitions are done in "net: mvpp2:
   simplify MVPP2_PRS_RI_* definitions" according to Russell King
   suggestions.

 - Add a patch "net: mvpp2: remove useless arguments in
   mvpp2_rx_{pkts,time}_coal_set", suggested by Russell King.

 - Rework mvpp2_rx_time_coal_set() implementation to avoid overflows
   and rounding errors. I've used the implementation suggested by
   Russell King.

Changes since v1:

 - This series is split as a separate series from the larger patch set
   adding support for PPv2.2 in the mvpp2 driver, as requested by
   David Miller.

 - Rebased on top of v4.10-rc1.

d3158807e8 net: mvpp2: enable building on 64-bit platforms
The mvpp2 is going to be extended to support the Marvell Armada 7K/8K
platform, which is ARM64. As a preparation to this work, this commit
enables building the mvpp2 driver on ARM64, by:

 - Adjusting the Kconfig dependency

 - Fixing the types used in the driver so that they are 32/64-bits
   compliant. We use dma_addr_t for DMA addresses, and unsigned long
   for virtual addresses.

It is worth mentioning that after this commit, the driver is for now
still only used on 32-bits platforms, and will only work on 32-bits
platforms.

0e0372816b net: mvpp2: switch to build_skb() in the RX path
This commit adapts the mvpp2 RX path to use the build_skb() method. Not
only build_skb() is now the recommended mechanism, but it also
simplifies the addition of support for the PPv2.2 variant.

Indeed, without build_skb(), we have to keep track for each RX
descriptor of the physical address of the packet buffer, and the virtual
address of the SKB. However, in PPv2.2 running on 64 bits platform,
there is not enough space in the descriptor to store the virtual address
of the SKB. So having to take care only of the address of the packet
buffer, and building the SKB upon reception helps in supporting PPv2.2.

The implementation is fairly straightforward:

 - mvpp2_skb_alloc() is renamed to mvpp2_buf_alloc() and no longer
   allocates a SKB. Instead, it allocates a buffer using the new
   mvpp2_frag_alloc() function, with enough space for the data and SKB.

 - The initialization of the RX buffers in mvpp2_bm_bufs_add() as well
   as the refill of the RX buffers in mvpp2_rx_refill() is adjusted
   accordingly.

 - Finally, the mvpp2_rx() is modified to use build_skb().

8138affc49 net: mvpp2: simplify MVPP2_PRS_RI_* definitions
Some of the MVPP2_PRS_RI_* definitions use the ~(value) syntax, which
doesn't compile nicely on 64-bit. Moreover, those definitions are in
fact unneeded, since they are always used in combination with a bit
mask that ensures only the appropriate bits are modified.

Therefore, such definitions should just be set to 0x0. In addition, as
suggested by Russell King, we change the _MASK definitions to also use
the BIT() macro so that it is clear they are related to the values
defined afterwards.

For example:

 #define MVPP2_PRS_RI_L2_CAST_MASK              0x600
 #define MVPP2_PRS_RI_L2_UCAST                  ~(BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

becomes

 #define MVPP2_PRS_RI_L2_CAST_MASK              (BIT(9) | BIT(10))
 #define MVPP2_PRS_RI_L2_UCAST                  0x0
 #define MVPP2_PRS_RI_L2_MCAST                  BIT(9)
 #define MVPP2_PRS_RI_L2_BCAST                  BIT(10)

Because the values (MVPP2_PRS_RI_L2_UCAST, MVPP2_PRS_RI_L2_MCAST and
MVPP2_PRS_RI_L2_BCAST) are always applied with
MVPP2_PRS_RI_L2_CAST_MASK, and therefore there is no need for
MVPP2_PRS_RI_L2_UCAST to be defined as ~(BIT(9) | BIT(10)).

It fixes the following warnings when building the driver on a 64-bit
platform (which is not possible as of this commit, but will be enabled
in a follow-up commit):

drivers/net/ethernet/marvell/mvpp2.c: In function ‘mvpp2_prs_mac_promisc_set’:

This commit drops dead code from the mvpp2 driver. The 'in_use' and

               return 0;

However 'is_recycle', passed as argument to mvpp2_rx_refill() is always
false. So in fact, this code is never reached, and the 'is_recycle'
argument is useless. So let's drop this code.

36fb7435b6 net: mvpp2: release reference to txq_cpu[] entry after unmapping
The mvpp2_txq_bufs_free() function is called upon TX completion to DMA
unmap TX buffers, and free the corresponding SKBs. It gets the
references to the SKB to free and the DMA buffer to unmap from a per-CPU
txq_pcpu data structure.

However, the code currently increments the pointer to the next entry
before doing the DMA unmap and freeing the SKB. It does not cause any
visible problem because for a given SKB the TX completion is guaranteed
to take place on the CPU where the TX was started. However, it is much
more logical to increment the pointer to the next entry once the current
entry has been completely unmapped/released.

ab42676af0 net: mvpp2: handle too large value in mvpp2_rx_time_coal_set()
When configuring the MVPP2_ISR_RX_THRESHOLD_REG with the RX coalescing
time threshold, we do not check for the maximum allowed value supported
by the driver, which means we might overflow and use a bogus value. This
commit adds a check for this situation, and if a value higher than what
is supported by the hardware is provided, then we use the maximum value
supported by the hardware.

In order to achieve this in a way that avoids overflow and rounding
errors, we introduce two utility functions mvpp2_usec_to_cycles() and
cycles_to_usec(). Many thanks to Russell King for suggesting this
implementation.

f8b0d5f8cc net: mvpp2: handle too large value handling in mvpp2_rx_pkts_coal_set()
Currently, mvpp2_rx_pkts_coal_set() does the following to avoid setting
a too large value for the RX coalescing by packet number:

  val = (pkts & MVPP2_OCCUPIED_THRESH_MASK);

This means that if you set a value that is slightly higher the the
maximum number of packets, you in fact get a very low value. It makes a
lot more sense to simply check if the value is too high, and if it's too
high, limit it to the maximum possible value.

d63f9e41f9 net: mvpp2: remove useless arguments in mvpp2_rx_{pkts, time}_coal_set
As noticed by Russell King, the last argument of
mvpp2_rx_{pkts,time}_coal_set() is useless, since the packet/time
coalescing value is already stored in the 'struct mvpp2_rx_queue *'
passed as argument to these functions. So passing the packet/time value
as an additional argument, and setting them again in the mvpp2_rx_queue
structure is useles.

This commit therefore gets rid of this additional argument, assuming the
caller has assigned the appropriate value to rxq->pkts_coal or
rxq->time_coal before calling the respective functions.

239a3b6636 net: mvpp2: fix DMA address calculation in mvpp2_txq_inc_put()
When TX descriptors are filled in, the buffer DMA address is split
between the tx_desc->buf_phys_addr field (high-order bits) and
tx_desc->packet_offset field (5 low-order bits).

However, when we re-calculate the DMA address from the TX descriptor in
mvpp2_txq_inc_put(), we do not take tx_desc->packet_offset into
account. This means that when the DMA address is not aligned on a 32
bytes boundary, we end up calling dma_unmap_single() with a DMA address
that was not the one returned by dma_map_single().

This inconsistency is detected by the kernel when DMA_API_DEBUG is
enabled. We fix this problem by properly calculating the DMA address in
mvpp2_txq_inc_put().

MACSec test failed when asynchronous crypto operations is used. It
encounters packet validation failed since macsec_skb_cb(skb)->valid
is always 'false'.

This patch adds missing "macsec_skb_cb(skb)->valid = true" in
macsec_decrypt_done() when "err == 0".

8ccde4c562 net: sock: Use USEC_PER_SEC macro instead of literal 1000000
The USEC_PER_SEC is used once in sock_set_timeout as the max value of
tv_usec. But there are other similar codes which use the literal
1000000 in this file.
It is minor cleanup to keep consitent.
