[PATCH] riscv: Fix 32b kernel build with CONFIG_DEBUG_VIRTUAL=y

From: Alexandre Ghiti
Date: Wed Apr 28 2021 - 06:02:31 EST


Declare kernel_virt_addr for 32b kernel since it is used in
__phys_addr_symbol defined when CONFIG_DEBUG_VIRTUAL is set.

Fixes: 2bfc6cd81bd17 ("riscv: Move kernel mapping outside of linear
mapping")
