9c6ee01ed5 Merge branch 'for-linus' of git://git.armlinux.org.uk/~rmk/linux-arm
Pull ARM updates from Russell King:
 "Lots of little things this time:

   - allow modules to be autoloaded according to the HWCAP feature bits
     (used primarily for crypto modules)

   - split module core and init PLT sections, since the core code and
     init code could be placed far apart, and the PLT sections need to
     be local to the code block.

   - three patches from Chris Brandt to allow Cortex-A9 L2 cache
     optimisations to be disabled where a SoC didn't wire up the out of
     band signals.

   - NoMMU compliance fixes, avoiding corruption of vector table which
     is not being used at this point, and avoiding possible register
     state corruption when switching mode.

   - fixmap memory attribute compliance update.

   - remove unnecessary locking from update_sections_early()

   - ftrace fix for DEBUG_RODATA with !FRAME_POINTER"

70ef8f0d37 for-f2fs-4.12
In this round, we've focused on enhancing performance with regards to block
 allocation, GC, and discard/in-place-update IO controls. There are a bunch
 of clean-ups as well as minor bug fixes.
 
 = Enhancement
 - disable heap-based allocation by default
 - issue small-sized discard commands by default
 - change the policy of data hotness for logging
 - distinguish IOs in terms of size and wbc type
 - start SSR earlier to avoid foreground GC
 - enhance data structures managing discard commands
 - enhance in-place update flow
 - add some more fault injection routines
 - secure one more xattr entry
 
 = Bug fix
 - calculate victim cost for GC correctly
 - remain correct victim segment number for GC
 - race condition in nid allocator and initializer
 - stale pointer produced by atomic_writes
 - fix missing REQ_SYNC for flush commands
 - handle missing errors in more corner cases

Now that kref is using the refcount apis, the _GPL markings are getting
exported to places that it previously wasn't.  Now kref.h is GPLv2
licensed, so any non-GPL code using it better be talking to some
lawyers, but changing api markings isn't considered "nice", so let's fix
this up.

37d69ee308 docs: bump minimal GNU Make version to 3.81
Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:

  $ git describe
  v4.11
  $ make --version | head -1
  GNU Make 3.80
  $ make defconfig
    HOSTCC  scripts/basic/fixdep
  scripts/Makefile.host:135: *** missing separator.  Stop.
  make: *** [defconfig] Error 2
  $ make ARCH=arm64 help

  ./Documentation/Makefile.sphinx:25: Extraneous text after `else' directive
  ./Documentation/Makefile.sphinx:31: *** only one `else' per conditional.  Stop.
  make: *** [help] Error 2

The first breakage was introduced by commit c8589d1e9e ("kbuild:
handle multi-objs dependency appropriately").  Since then (i.e. v3.18),
GNU Make 3.80 has not been able to compile the kernel, but nobody has
ever complained aboutt (or noticed) it.

Even GNU Make 3.81 is more than 10 years old.  It would not hurt to
match the documentation with reality instead of fixing makefiles.

a statement after a label, or you'll get complaints:

  init/initramfs.c: In function 'populate_rootfs':
  init/initramfs.c:644:2: error: label at end of compound statement

That commit moved the subsequent statements to outside the compound
statement, leaving the label without any associated statements.

53ef7d0e20 libnvdimm for 4.12
* Region media error reporting: A libnvdimm region device is the parent
 to one or more namespaces. To date, media errors have been reported via
 the "badblocks" attribute attached to pmem block devices for namespaces
 in "raw" or "memory" mode. Given that namespaces can be in "device-dax"
 or "btt-sector" mode this new interface reports media errors
 generically, i.e. independent of namespace modes or state. This
 subsequently allows userspace tooling to craft "ACPI 6.1 Section
 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and
 submit them via the ioctl path for NVDIMM root bus devices.
 
 * Introduce 'struct dax_device' and 'struct dax_operations': Prompted by
 a request from Linus and feedback from Christoph this allows for dax
 capable drivers to publish their own custom dax operations. This fixes
 the broken assumption that all dax operations are related to a
 persistent memory device, and makes it easier for other architectures
 and platforms to add customized persistent memory support.
 
 * 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
 available for storage appliance applications to manually trigger memory
 controllers to drain write-pending buffers that would otherwise be
 flushed automatically by the platform ADR (asynchronous-DRAM-refresh)
 mechanism at a power loss event. Support for "locked" DIMMs is included
 to prevent namespaces from surfacing when the namespace label data area
 is locked. Finally, fixes for various reported deadlocks and crashes,
 also tagged for -stable.
 
 * ACPI / nfit driver updates: General updates of the nfit driver to add
 DSM command overrides, ACPI 6.1 health state flags support, DSM payload
 debug available by default, and various fixes.

c6a677c6f3 Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1.  And it's a big one,
 adding about 350k new lines of crap^Wcode, mostly all in a big dump of
 media drivers from Intel.  But there's other new drivers in here as
 well, yet-another-wifi driver, new IIO drivers, and a new crypto
 accelerator.  We also deleted a bunch of stuff, mostly in patch
 cleanups, but also the Android ION code has shrunk a lot, and the
 Android low memory killer driver was finally deleted, much to the
 celebration of the -mm developers.
 
 All of these have been in linux-next with a few build issues that will
 show up when you merge to your tree, I'll follow up with fixes for those
 after this gets merged.

1a5fb64fee We've got ten GFS2 patches for this merge window.
1. Andreas Gruenbacher wrote a patch to replace the deprecated
    call to rhashtable_walk_init with rhashtable_walk_enter.
 2. Andreas also wrote a patch to eliminate redundant code in
    two of our debugfs sequence files.
 3. Andreas also cleaned up the rhashtable key ugliness Linus
    pointed out during this cycle, following Linus's suggestions.
 4. Andreas also wrote a patch to take advantage of his new
    function rhashtable_lookup_get_insert_fast. This makes glock
    lookup faster and more bullet-proof.
 5. Andreas also wrote a patch to revert a patch in the evict
    path that caused occasional deadlocks, and is no longer
    needed.
 6. Andrew Price wrote a patch to re-enable fallocate for the
    rindex system file to enable gfs2_grow to grow properly on
    secondary file system grow operations.
 7. I wrote a patch to initialize an inode number field to make
    certain kernel trace points more understandable.
 8. I also wrote a patch that makes GFS2 file system "withdraw"
    work more like it should by ignoring operations after a
    withdraw that would formerly cause a BUG() and kernel panic.
 9. I also reworked the entire truncate/delete algorithm,
    scrapping the old recursive algorithm in favor of a new
    non-recursive algorithm. This was done for performance:
    This way, GFS2 no longer needs to lock multiple resource
    groups while doing truncates and deletes of files that cross
    multiple resource group boundaries, allowing for better
    parallelism. It also solves a problem whereby deleting large
    files would request a large chunk of kernel memory, which
    resulted in a get_page_from_freelist warning.
 10. Due to a regression found during testing, I added a new
     patch to correct "GFS2: Prevent BUG from occurring when
     normal Withdraws occur".

ed17545d01 GFS2: Allow glocks to be unlocked after withdraw
This bug fixes a regression introduced by patch 0d1c7ae9d8.

The intent of the patch was to stop promoting glocks after a
file system is withdrawn due to a variety of errors, because doing
so results in a BUG(). (You should be able to unmount after a
withdraw rather than having the kernel panic.)

Unfortunately, it also stopped demotions, so glocks could not be
unlocked after withdraw, which means the unmount would hang.

This patch allows function do_xmote to demote locks to an
unlocked state after a withdraw, but not promote them.

161f55efba xfs: fix use-after-free in xfs_finish_page_writeback
Commit 28b783e47a ("xfs: bufferhead chains are invalid after
end_page_writeback") fixed one use-after-free issue by
pre-calculating the loop conditionals before calling bh->b_end_io()
in the end_io processing loop, but it assigned 'next' pointer before
checking end offset boundary & breaking the loop, at which point the
bh might be freed already, and caused use-after-free.

This is caught by KASAN when running fstests generic/127 on sub-page
block size XFS.

7246f60068 powerpc updates for 4.12 part 1.
Highlights include:
 
  - Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
    virtual address space, but a process can request access to the full 512TB by
    passing a hint to mmap().
 
  - Support for the new Power9 "XIVE" interrupt controller.
 
  - TLB flushing optimisations for the radix MMU on Power9.
 
  - Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
    Architecture 2.0".
 
  - The ability to configure the mmap randomisation limits at build and runtime.
 
  - Several small fixes and cleanups to the kprobes code, as well as support for
    KPROBES_ON_FTRACE.
 
  - Major improvements to handling of system reset interrupts, correctly treating
    them as NMIs, giving them a dedicated stack and using a new hypervisor call
    to trigger them, all of which should aid debugging and robustness.
 
 Many fixes and other minor enhancements.

92f66f84d9 arm64: Fix the DMA mmap and get_sgtable API with DMA_ATTR_FORCE_CONTIGUOUS
While honouring the DMA_ATTR_FORCE_CONTIGUOUS on arm64 (commit
44176bb38f: "arm64: Add support for DMA_ATTR_FORCE_CONTIGUOUS to
IOMMU"), the existing uses of dma_mmap_attrs() and dma_get_sgtable()
have been broken by passing a physically contiguous vm_struct with an
invalid pages pointer through the common iommu API.

Since the coherent allocation with DMA_ATTR_FORCE_CONTIGUOUS uses CMA,
this patch simply reuses the existing swiotlb logic for mmap and
get_sgtable.

Note that the current implementation of get_sgtable (both swiotlb and
iommu) is broken if dma_declare_coherent_memory() is used since such
memory does not have a corresponding struct page. To be addressed in a
subsequent patch.

17a9be3174 initramfs: Always do fput() and load modules after rootfs populate
In OpenRISC we do not have a bootloader passed initrd, but the built in
initramfs does contain the /init and other binaries, including modules.
The previous commit 0886551480 ("initramfs: finish fput() before
accessing any binary from initramfs") made a change to only call fput()
if the bootloader initrd was available, this caused intermittent crashes
for OpenRISC.

This patch changes the fput() to happen unconditionally if any rootfs is
loaded. Also, I added some comments to make it a bit more clear why we
call unpack_to_rootfs() multiple times.

In commit 658922e57b "libnvdimm, pfn: fix memmap reservation sizing"
we arranged for the capacity to be allocated, but failed to also update
the 'npfns' parameter. This leads to cases where there is enough
capacity reserved to hold all the allocated sections, but
vmemmap_populate_hugepages() still encounters -ENOMEM from
altmap_alloc_block_buf().

This fix is a stop-gap until we can teach the core memory hotplug
implementation to permit sub-section hotplug.

644b4930bf drm/tegra: Changes for v4.12-rc1
This contains various fixes to the host1x driver as well as a plug for a
 leak of kernel pointers to userspace.
 
 A fairly big addition this time around is the Video Image Composer (VIC)
 support that can be used to accelerate some 2D and image compositing
 operations.
 
 Furthermore the driver now supports FB modifiers, so we no longer rely
 on a custom IOCTL to set those.
 
 Finally this contains a few preparatory patches for Tegra186 support
 which unfortunately didn't quite make it this time, but will hopefully
 be ready for v4.13.

drm/tegra: Changes for v4.12-rc1

This contains various fixes to the host1x driver as well as a plug for a
leak of kernel pointers to userspace.

A fairly big addition this time around is the Video Image Composer (VIC)
support that can be used to accelerate some 2D and image compositing
operations.

Furthermore the driver now supports FB modifiers, so we no longer rely
on a custom IOCTL to set those.

Finally this contains a few preparatory patches for Tegra186 support
which unfortunately didn't quite make it this time, but will hopefully
be ready for v4.13.

Very tiny pull request for 4.12-rc1 for the driver core this time
 around.
 
 There are some documentation fixes, an eventpoll.h fixup to make it
 easier for the libc developers to take our header files directly, and
 some very minor driver core fixes and changes.
 
 All have been in linux-next for a very long time with no reported

8f28472a73 USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1.
 
 Lots of good stuff here, after many many many attempts, the kernel
 finally has a working typeC interface, many thanks to the Heikki and
 Guenter and others who have taken the time to get this merged.  It
 wasn't an easy path for them at all.
 
 There's also a staging driver that uses this new api, which is why it's
 coming in through this tree.
 
 Along with that, there's the usual huge number of changes for gadget
 drivers, xhci, and other stuff.  Johan also finally refactored pretty
 much every driver that was looking at USB endpoints to do it in a common
 way, which will help prevent any "badly-formed" devices from causing
 problems in drivers.  That too wasn't a simple task.
 
 All of these have been in linux-next for a while with no reported

9d62ed9651 libnvdimm: handle locked label storage areas
Per the latest version of the "NVDIMM DSM Interface Example" [1], the
label data retrieval routine can report a "locked" status. In this case
all regions associated with that DIMM are disabled until the label area
is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label
data area locking capabilities.

8f078b38dd libnvdimm: convert NDD_ flags to use bitops, introduce NDD_LOCKED
This is a preparation patch for handling locked nvdimm label regions, a
new concept as introduced by the latest DSM document on pmem.io [1]. A
future patch will leverage nvdimm_set_locked() at DIMM probe time to
flag regions that can not be enabled. There should be no functional
difference resulting from this change.

2bd8040174 This is the bulk of GPIO changes for the v4.12 kernel cycle:
Core changes
 
 - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
   This was a much discussed change. It affects use cases where people
   write drivers that might or might not be using GPIO resources.
   I have decided that this is the lesser evil right now.
 
 - Make gpiod_count() behave consistently across different hardware
   descriptions.
 
 - Fix the syntax around open drain/open source to not infer active
   high/low semantics.
 
 New drivers
 
 - A new single-register fixed-direction framework driver for hardware
   that have lines controlled by a single register that just work in
   one direction (out or in), including IRQ support.
 
 - Support the Fintek F71889A GPIO SuperIO controller.
 
 - Support the National NI 169445 MMIO GPIO.
 
 - Support for the X-Gene derivative of the DWC GPIO controller
 
 - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
 
 - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
   and replace both the Gemini and the Moxa ART custom drivers with
   this driver.
 
 Driver improvements
 
 - A whole slew of drivers have their spinlocks chaned to raw spinlocks
   as they provide irqchips, and thus we are progressing on realtime
   compliance.
 
 - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
   resources.
 
 - Support for the embedded PWM controller inside the MVEBU driver.
 
 - Debounce, open source and open drain support for the Aspeed driver.
 
 - Misc smaller fixes like spelling and syntax and whatnot.

Pull x86 platform-drivers update from Darren Hart:
 "This represents a significantly larger and more complex set of changes
  than those of prior merge windows.

  In particular, we had several changes with dependencies on other
  subsystems which we felt were best managed through merges of immutable
  branches, including one each from input, i2c, and leds. Two patches
  for the watchdog subsystem are included after discussion with Wim and
  Guenter following a collision in linux-next (this should be resolved
  and you should only see these two appear in this pull request). These
  are called out in the "External" section below.

  Summary of changes:
   - significant further cleanup of fujitsu-laptop and hp-wmi
   - new model support for ideapad, asus, silead, and xiaomi
   - new hotkeys for thinkpad and models using intel-vbtn
   - dell keyboard backlight improvements
   - build and dependency improvements
   - intel * ipc fixes, cleanups, and api updates

2f713b5c7d orangefs: count directory pieces correctly

Most directories, even very large directories with shorter names, would
be lucky enough to fit in one server response.
