From 735c4fb916e9f83a9350aeb2680d77d01ea75094 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Tue, 4 Mar 2008 14:28:40 -0800 Subject: add noinline_for_stack People are adding `noinline' in various places to prevent excess stack consumption due to gcc inlining. But once this is done, it is quite unobvious why the `noinline' is present in the code. We can comment each and every site, or we can use noinline_for_stack.
