   - [PATCH v2 5/8] xen/riscv: introduce asm/pmap.h header
   - [PATCH v3 6/9] xen/riscv: introduce functionality to work with cpu info
   - [PATCH v3 7/9] xen/riscv: introduce and init SBI RFENCE extension
 - All other changes are patch specific so please look at the patch.
---
Changes in v8:

 - Introduce and initialize pcpu_info[] and __cpuid_to_hartid_map[] and functionality
   to work with this arrays.
 - Make page table handling arch specific instead of trying to make it generic.
