copy_mc_fragile_handle_tail() is only called from assembler,
but 'make W=1' complains about a missing prototype:

arch/x86/lib/copy_mc.c:26:1: warning: no previous prototype for ‘copy_mc_fragile_handle_tail’ [-Wmissing-prototypes]
   26 | copy_mc_fragile_handle_tail(char *to, char *from, unsigned len)

Add the prototype to avoid the warning.
