Enable generic earlycon support for nios2. This e.g. allows to use a
8250/16650 UART as earlycon.

In order to get the earlycon, we just need to call parse_early_param()
in early_init_devtree() as soon as the device tree is initially scanned.
By adding an stdout-path property to the dts (done in this patch for
10m50_devboard), the earlycon can be used.

In order to provide early printk support, we need to provide a dummy
implementation of early_console_write(), so that
arch/nios2/kernel/early_printk.c can still be compiled if neither
SERIAL_ALTERA_JTAGUART_CONSOLE nor SERIAL_ALTERA_UART_CONSOLE is
selected. As soon as the altera_uart and altera_jtaguart support
earlycon, the entire file can be removed.

Since 2014, you can't successfully build kernels with GNU Make version
3.80. Example errors:

  $ git describe

  $ make --version | head -1
  GNU Make 3.80
  $ make defconfig

  scripts/Makefile.host:135: *** missing separator.  Stop.

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

The first breakage was introduced by commit c8589d1e ("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.

Pull libnvdimm updates from Dan Williams:
 "The bulk of this has been in multiple -next releases. There were a few
  late breaking fixes and small features that got added in the last
  couple days, but the whole set has received a build success
  notification from the kbuild robot.

  Change summary:

   - 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.

Pull GFS2 updates from Bob Peterson:
 "We've got ten GFS2 patches for this merge window.

   - Andreas Gruenbacher wrote a patch to replace the deprecated call to
     rhashtable_walk_init with rhashtable_walk_enter.

   - Andreas also wrote a patch to eliminate redundant code in two of
     our debugfs sequence files.

   - Andreas also cleaned up the rhashtable key ugliness Linus pointed
     out during this cycle, following Linus's suggestions.

   - 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.

   - Andreas also wrote a patch to revert a patch in the evict path that
     caused occasional deadlocks, and is no longer needed.

   - 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.

   - I wrote a patch to initialize an inode number field to make certain
     kernel trace points more understandable.

   - 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.

   - 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.

   - Due to a regression found during testing, I added a new patch to
     correct 'GFS2: Prevent BUG from occurring when normal Withdraws
     occur'."

  Bug fixes:

   - do not check possibly stale size on truncate
   - ensure the userspace component is unmounted if mount fails
   - total reimplementation of dir.c

  New feature:

   - implement statx

  The new implementation of dir.c is kind of a big deal, all new code.
  It has been posted to fs-devel during the previous rc period, we
  didn't get much review or feedback from there, but it has been
  reviewed very heavily here, so much so that we have two entire
  versions of the reimplementation.

  Not only does the new implementation fix some xfstests, but it passes
  all the new tests we made here that involve seeking and rewinding and
  giant directories and long file names. The new dir code has three
  patches itself:

   - skip forward to the next directory entry if seek is short
   - invalidate stored directory on seek
   - count directory pieces correctly"

  suggested submitting directly to you.

* tag 'initramfs-fix-4.12-rc1' of git://github.com/stffrdhrn/linux:
  initramfs: Always do fput() and load modules after rootfs populate

This bug fixes a regression introduced by patch 0d1c7ae9.

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.

Commit 28b783e4 ("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.

While honouring the DMA_ATTR_FORCE_CONTIGUOUS on arm64 (commit
44176bb3: "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.

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 08865514 ("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.

Besides formalizing things a bit more I don't think this changes
anything for us, we've already peer-enforced respectful and
