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)

Convert byte order of constant instead of variable it will be done at
compile time vs run time. Remove unused le32_and_cpu.

Writes to a region marked as unwritten might result in a record split or
merge. We can support splits by making minor changes to the existing insert
code. Merges require left rotations which mostly re-use right rotation
support functions.
