Linus Torvalds 8b83369ddc RISC-V Patches for the 5.12 Merge Window
I have 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.
