riscv: Improve kasan population by using hugepages when possible (2021-02-22 18:54:17 -0800)

----------------------------------------------------------------
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.

---

We have a handful of merge conflicts this round. Here are my resolutions. The
arm64 one was part of the NUMA cleanup, the other two were part of the Kendryte
rename (it's Canaan now, and it's alphabetically sorted).
