From 8ab4a7de12a2fc776822c82cc4233a37b35c40f3 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Mon, 28 May 2012 18:31:39 -0400 Subject: [PATCH] Set noinline on kbd.c interface functions that take stack variable pointers. Some versions of gcc have been found to inline these funcions and then cause the calling functions to use very large stack usage. Since these functions are called from 16bit mode, their stack space usage is very sensitive.
