[PATCH v1 00/57] Enable build of full Xen for RISC-V

[Oleksii Kurochko <oleksii.kurochko@gmail.com>]

This patch series performs all of the additions necessary to drop the
build overrides for RISCV and enable the full Xen build. Except in cases
where compatibile implementations already exist (e.g. atomic.h and
bitops.h), the newly added definitions are simple.

Also the patch series has open question described in the patch 57

Patch 56 is only needed for test purposes and will be removed.
