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]

Changes in V2:
  - Drop the following patches as they are the part of [2]:
      [PATCH v1 06/57] xen/riscv: introduce paging.h

      [PATCH v1 10/57] xen/riscv: introduce asm/grant_table.h
      [PATCH v1 12/57] xen/riscv: introduce asm/hypercall.h
      [PATCH v1 13/57] xen/riscv: introduce asm/iocap.h
      [PATCH v1 15/57] xen/riscv: introduce asm/mem_access.h
      [PATCH v1 18/57] xen/riscv: introduce asm/random.h
      [PATCH v1 21/57] xen/riscv: introduce asm/xenoprof.h
      [PATCH v1 24/57] xen/riscv: introduce asm/percpu.h
      [PATCH v1 29/57] xen/riscv: introduce asm/hardirq.h

      [PATCH v1 39/57] xen/riscv: introduce asm/numa.h
      [PATCH v1 42/57] xen/riscv: introduce asm/softirq.h
  - xen/lib.h in most of the cases were changed to xen/bug.h as
    mostly functionilty of bug.h is used.
  - align arch-riscv.h with Arm's version of it.
  - change the Author of commit with introduction of asm/atomic.h.
  - update some definition from spinlock.h.
  - code style changes.

Throughout here, would you please try to be consistent about (not) using asm/
prefixes?

Sure. I'll skip asm, there is no any sense to use it as it is mentioned
xen/riscv...
