Hi,

This new version removed the translate_fn() from patch 1 because it
wasn't removing the sign-extension for pentry as we thought it would.
A more detailed explanation is given in the commit msg of patch 1.

We're now retrieving the 'lowaddr' value from load_elf_ram_sym() and
using it when we're running a 32-bit CPU. This worked with 32 bit
'virt' machine booting with the -kernel option.

If this approach doesn't work for the Xvisor use case, IMO  we should
just filter kernel_load_addr bits directly as we were doing a handful of
versions ago.

Patches are based on current riscv-to-apply.next. 

Changes from v9:
- patch 1:
  - removed the translate_fn() callback
  - return 'kernel_low' when running a 32-bit CPU
- v9 link: https://lists.gnu.org/archive/html/qemu-devel/2023-01/msg04509.html
