[PATCH] Add missing __KERNEL__ (or other) protections

As of 2.6.10-rc3, the following is needed to allow various userland
packages (sysvinit, dhcp, ppp, libcap, libpcap, lilo) to compile as parts
that userland needs (e.g.  for ioctls) is in files with stuff userland
isn't allowed to see.

This adds __KERNEL__ around <linux/ata.h> and some defines (<linux/ata.h>
isn't needed by userland, and is unhappy right now).  sysvinit and some
other packages need <linux/hdreg.h> for HDIO_DRIVE_CMD and other IOCTL
things.  In <linux/types.h> we were unsafely typedef'ing __le64/__be64 as
__u64 only exists when __GNUC__ && !__STRICT_ANSI__ (causing libcap to
fail, for example).  Finally, <asm/atomic.h> provides routines userland
simply cannot use on all arches, but <linux/filter.h> is needed by iputils
for example.  While not all arches put __KERNEL__ around their header, on
MIPS including this header currently blows up the build.
