This patch series is against the powerpc next branch. It takes advantage of the fact that there are only a few CPU feature bits that are meaningful on both 32-bit and 64-bit platforms. At the moment, many of the 64 bits of the CPU feature mask on 64-bit platforms are taken up with bits which are only relevant to 32-bit platforms. This series rearranges things so that we can use those bits for new features that are relevant only to 64-bit platforms. With this, there are now 20 bits available for new 64-bit features.
To make things simpler, we use the bottom 12 bits of the CPU feature word for features that are relevant to both 32-bit and 64-bit platforms. The remaining 20 or 52 bits are then available for features specific to 32-bit or 64-bit platforms.
