Sometimes simple attributes might need to return an error, e.g. for
acquiring a mutex interruptibly.  In fact we have that situation in
spufs already which is the original user of the simple attributes.  This
patch merged the temporarily forked attributes in spufs back into the
main ones and allows to return errors.

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)

An AoE target provides an estimate of the number of outstanding commands that
the AoE initiator can send before getting a response.  The aoe_maxout
parameter provides a way to set an even lower limit.  It will not allow a user
to use more outstanding commands than the target permits.  If a user discovers
a problem with a large setting, this parameter provides a way for us to work
with them to debug the problem.  We expect to improve the dynamic window
sizing algorithm and drop this parameter.  For the time being, it is a
debugging aid.
