[PATCH 5.17 596/772] RISC-V: Fix the XIP build

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 17:31:51 EST


From: Palmer Dabbelt <palmer@xxxxxxxxxxxx>

[ Upstream commit d9e418d0ca1c464fe361468b772d4aa870d54e63 ]

A handful of functions unused functions were enabled during XIP builds,
which themselves didn't build correctly. This just disables the
functions entirely.

Fixes: e8a62cc26ddf ("riscv: Implement sv48 support")
