#     Pull RISC-V fixes from Palmer Dabbelt:
#      "Two fixes this week:
#     
#        - A fix to actually reserve the device tree's memory. Without this
#          the device tree can be overwritten on systems that don't otherwise
#          reserve it. This issue should only manifest on !MMU systems.
#     
#        - A workaround for a BUG() that triggers when the memory that
#          originally contained initdata is freed and later repurposed. This
#          triggers a BUG() on builds that had HARDENED_USERCOPY enabled"
