<<
The corenet64 patch fixes a regression introduced in 3.13-rc1 (commit
ef1313deafb7baa6d3382044e962d5ad5e8c8dd6, "powerpc: Add VMX optimised xor
for RAID5").

The 8xx patch fixes a regression introduced in 3.12 (commit
beb2dc0a7a84be003ce54e98b95d65cc66e6e536, "powerpc: Convert some
mftb/mftbu into mfspr").

The other two patches are fixes for minor, long standing bugs.
