Pull devicetree fixes from Rob Herring:

 - Fix fw_devlink failure with ".*,nr-gpios" properties

 - Doc link reference fixes from Mauro

 - Fixes for unaligned FDT handling found on OpenRisc. First, avoid
   crash with better error handling when unflattening an unaligned FDT.
   Second, fix memory allocations for FDTs to ensure alignment.

The iio-bindings.txt was converted into two files and merged
at the dt-schema git tree at:

	https://github.com/devicetree-org/dt-schema

Yet, some documents still refer to the old file. Fix their
references, in order to point to the right URL.

As documents have been renamed and moved around, their
references will break, but this will be unnoticed, as the
script which checks for it won't handle "../" references.

So, replace them by the full patch.

Pull RISC-V updates from Palmer Dabbelt:
 "A handful of new RISC-V related patches for this merge window:

   - A check to ensure drivers are properly using uaccess. This isn't
     manifesting with any of the drivers I'm currently using, but may
     catch errors in new drivers.

   - Some preliminary support for the FU740, along with the HiFive
     Unleashed it will appear on.

   - NUMA support for RISC-V, which involves making the arm64 code
     generic.

   - Support for kasan on the vmalloc region.

   - A handful of new drivers for the Kendryte K210, along with the DT
     plumbing required to boot on a handful of K210-based boards.

   - Support for allocating ASIDs.

   - Preliminary support for kernels larger than 128MiB.

   - Various other improvements to our KASAN support, including the
     utilization of huge pages when allocating the KASAN regions.

  We may have already found a bug with the KASAN_VMALLOC code, but it's
  passing my tests. There's a fix in the works, but that will probably
  miss the merge window.
