[ Upstream commit a6c3ea1ec96307dbfbb2f16d96c674c5cc80f445 ]
Remove the unused cif_stack argument and add a protype in oplib_64.h Commit ef3e035c3a9b ("sparc64: Fix register corruption in top-most kernel stack frame during boot.") removed the cif_stack argument to prom_cif init in the declaration at the caller site and the usage of it within prom_cif_init, but not in the function signature of the function itself.
This also fixes the following warning: arch/sparc/prom/p1275.c:52:6: warning: no previous prototype for ‘prom_cif_init’
