Subject: when CONFIG_CC_OPTIMIZE_FOR_SIZE, allow gcc4 to control inlining From: Ingo Molnar <mingo@elte.hu>
if optimizing for size (CONFIG_CC_OPTIMIZE_FOR_SIZE), allow gcc4 compilers to decide what to inline and what not - instead of the kernel forcing gcc to inline all the time. This requires several places that require to be inlined to be marked as such, previous patches in this series do that. This is probably the most flame-worthy patch of the series.
