commit b9c220b589daaf140f5b8ebe502c98745b94e65c upstream.

Selecting CONFIG_RANDOMIZE_BASE=y and CONFIG_MODULES=n fails to build the module PLTs support:

CC arch/arm64/kernel/module-plts.o
/work/Linux/linux-2.6-aarch64/arch/arm64/kernel/module-plts.c: In function ‘module_emit_plt_entry’:
/work/Linux/linux-2.6-aarch64/arch/arm64/kernel/module-plts.c:32:49: error: dereferencing pointer to incomplete type ‘struct module’

This patch selects ARM64_MODULE_PLTS conditionally only if MODULES is enabled.
