The patch series introduces the following things:
1. Functionality to build the page tables for Xen that map the
   following:
     * The physical location of Xen (where the bootloader loaded it)
     * The link-time location of Xen (where the linker expected Xen's
       addresses to be.
2. Load the built page table into the SATP
3. Enables MMU.
4. Updates smoke test to grep message which should be printed after
   MMU is enabled.

Oleksii Kurochko (3):
  xen/riscv: introduce setup_initial_pages
  xen/riscv: setup initial pagetables
  automation: update RISC-V smoke test

I forgot to mention in cover letter that the patch series is based on
top of 'introduce generic implementation of macros from bug.h' and
'RISCV basic exception handling implementation' patch series.
