smp, metag: kill SMP single function call interrupt
Commit 9a46ad6d6d
"smp: make smp_call_function_many() use logic
similar to smp_call_function_single()" has unified the way to handle
single and multiple cross-CPU function calls. Now only one interrupt is
needed for architecture specific code to support generic SMP function
call interfaces, so kill the redundant single function call interrupt.
