740 * When building the kernel with -O2 on the i386 architecture, gcc
741 * seems to want to inline this function into ieee80211_ioctl()
742 * (which is the only routine that calls it). When this happens,
743 * ieee80211_ioctl() ends up consuming an additional 2K of stack
744 * space. (Exactly why it needs so much is unclear.) The problem
745 * is that it's possible for ieee80211_ioctl() to invoke other
746 * routines (including driver init functions) which could then find
747 * themselves perilously close to exhausting the stack.
748 *
749 * To avoid this, we deliberately prevent gcc from inlining this
750 * routine. Another way to avoid this is to use less agressive
751 * optimization when compiling this file (i.e. -O instead of -O2)
752 * but special-casing the compilation of this one module in the
753 * build system would be awkward.
