The following moves all includes <linux/fs.h> (except <linux/ioctl.h>
and <linux/config.h> down to below the existing __KERNEL__ test. None
of these includes are needed by the user-visible portions of the header,
and in some cases can cause userland apps to break. For example, LTP
and sash with an empty <linux/autoconf.h> will fail thusly:
cc -Wall -I../../include -g -Wall -I../../../../include -Wall setrlimit02.c -L../../../../lib -lltp -o setrlimit02
In file included from /usr/include/asm/atomic.h:6,
from /usr/include/linux/fs.h:20,
from setrlimit02.c:46:
/usr/include/asm/processor.h:68: error: `CONFIG_X86_L1_CACHE_SHIFT' undeclared here (not in a function)
/usr/include/asm/processor.h:68: error: requested alignment is not a constant
Build/run tested with a glibc rebuild as well.

Move limits.h include back above __KERNEL__ to quiet things back down.
