Subject: [PATCH] m32r: mm: fix build warning
While building we are getting warnings:
arch/m32r/mm/init.c:63:17: warning: unused variable 'low'
arch/m32r/mm/init.c:62:17: warning: unused variable 'max_dma'
max_dma and low are only used if CONFIG_MMU is defined. Lets declare the
variables inside the #ifdef.
