Subject: ARM: 8648/2: nommu: display vectors base
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58c16709f9cad7e6daabeaa5c94ac4dcb260aedd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: 8648/2: nommu: display vectors base

VECTORS_BASE displays the exception base address. Now on no-MMU as
the exception base address is dynamically estimated, define
VECTORS_BASE to the variable holding it.

As it is the case, limit VECTORS_BASE constant definition to MMU.
