Pull RISC-V fixes from Palmer Dabbelt:

 - prevent users from enabling the alternatives framework (and thus
   errata handling) on XIP kernels, where runtime code patching does not
   function correctly.

 - properly detect offset overflow for AUIPC-based relocations in
   modules. This may manifest as modules calling arbitrary invalid
   addresses, depending on the address allocated when a module is
   loaded.
