  RISC-V: Use SBI SRST extension when available (2022-01-11 10:25:43 -0800)

----------------------------------------------------------------
RISC-V Patches for the 5.17 Merge Window, Part 1

* Support for the DA9063 as used on the HiFive Unmatched.
* Support for relative extables, which puts us in line with other
  architectures and save some space in vmlinux.
* A handful of kexec fixes/improvements, including the ability to run
  crash kernels from PCI-addressable memory on the HiFive Unmatched.
* Support for the SBI SRST extension, which allows systems that do not
  have an explicit driver in Linux to reboot.
* A handful of fixes and cleanups, including to the defconfigs and
  device trees.

This time I do expect to have a part 2, as there's still some smaller
patches on the list.  I was hoping to get through more of that over the
weekend, but I got distracted with the ABI issues.  Figured it's better
to send this sooner rather than waiting.

Included are my merge resolutions against a master from this morning, if
that helps any:
