compiler-gcc4: conditionalize #error on __KERNEL__
Impact: Fix for exported headers We only want to error out on specific gcc versions if we are actually building the kernel, so conditionalize the #if...#error on __KERNEL__. Based on a patchset by Arnd Bergmann <arnd@arndb.de>. Cc: Arnd Bergmann <arnd@arndb.de> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
