[PATCH v2 00/39] Enable build of full Xen for RISC-V

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

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.

The patch series is based on the following patch series:
- [PATCH v2] xen: remove <asm/delay.h> [1]
- [PATCH v3 00/14] Introduce generic headers [2]
