The Kconfigs for in-tree floating point emulation do not allow building as modules. That leaves the Acorn FPEmulator module. I found two public releases of this as a binary module for 2.1 and 2.2 kernels, optimized for ARMV4.[1] If there is a resurgence of interest in this, the symbols can always be re-exported. This allows the EXPORT_SYMBOL_ALIAS() hack to be removed. The ulterior motive here is that EXPORT_SYMBOL_ALIAS() makes it harder to sort the resulting kernel symbol tables. Sorted symbol tables will allow faster symbol resolution during module loading. Note that fp_send_sigs() and fp_printk() are simply aliases for existing exports and add no obvious value. Similarly fp_enter could easily be renamed to kern_fp_enter at the point of definition. Therefore removing EXPORT_SYMBOL_ALIAS will not serve as a material obstacle to re-adding the exports should they be desired in future. Build tested only.
