Fix up the contents of <linux/byteorder/> so that it doesn't export a
content-free generic.h to user space. This involves:
* Removing the __KERNEL__ tests from generic.h and dropping it from
Kbuild.
* Wrapping the inclusions of generic.h in both big_endian.h and
little_endian.h in __KERNEL__ tests.
* Shifting big_endian.h and little_endian.h from header-y to
unifdef-y in Kbuild.

This patchset moves le*_add_cpu and be*_add_cpu functions from OCFS2 to core
header (1st), converts ext3 filesystem to this API (2nd) and replaces XFS
different named functions with new ones (3rd).
There are many places where these functions will be useful. Just look at:
grep -r 'cpu_to_[ble12346]*([ble12346]*_to_cpu.*[-+]' linux-src/ Patch for
ext3 is an example how conversions will probably look like.
This patch:
- move inline functions which add native byte order variable to
little/big endian variable to core header
* le16_add_cpu(__le16 *var, u16 val)
* le32_add_cpu(__le32 *var, u32 val)
* le64_add_cpu(__le64 *var, u64 val)
* be32_add_cpu(__be32 *var, u32 val)
- add for completeness:
* be16_add_cpu(__be16 *var, u16 val)
* be64_add_cpu(__be64 *var, u64 val)

It is sometimes useful to compile individual drivers with optimization
disabled for easier debugging. Currently drivers which use htonl() and
similar functions don't compile with -O0. This patch fixes it. It also
removes obsolete and misleading comments. This header is not for
userspace, so we don't have to care about strange programs these comments
mention.
(akpm: -O0 probably isn't a good idea, but this code looks pretty crufty and
unuseful)

This patch comments the fact that although passing le64_to_cpup et
al. is within the intended use of the byteorder macros, using
get_unaligned is the recommended way to go.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
