CONFIG_ARM_MODULE_PLTS: Use PLTs to allow module memory to spill over into vmalloc area

General informations

The Linux kernel configuration item CONFIG_ARM_MODULE_PLTS:

Help text

Allocate PLTs when loading modules so that jumps and calls whose targets are too far away for their relative offsets to be encoded in the instructions themselves can be bounced via veneers in the module's PLT. This allows modules to be allocated in the generic vmalloc area after the dedicated module memory area has been exhausted. The modules will use slightly more memory, but after rounding up to page size, the actual memory footprint is usually the same.

Disabling this is usually safe for small single-platform configurations. If unsure, say y.
