It was a stupid workaround for the "static inline" vs. "extern inline" issues of long ago, and it is what causes schedule() to be inlined like crazy into kernel/sched.c when -Os is specified. MIPS and S390 should probably do the same. Now CC_OPTIMIZE_FOR_SIZE can be safely used on sparc64 once more. Signed-off-by: David S. Miller <davem@davemloft.net>
