Could you please apply below patch to fix the error?
From f6ac7bddfc5969b0982ddf52ab248a1abb0b90a8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] lib/Kconfig.debug: make CONFIG_TEST_VMALLOC depends on
CONFIG_MMU
The vmalloc test driver can not be used on no-MMU systems. Add that
dependency to prevent the driver to be compiled on such systems.
