There's a rather hefty pull request of PowerPC architecture updates pending for the Linux 4.5 kernel.

Some of the PowerPC updates for Linux 4.5 include the ground support for a new Power9 MMU, optimized FP/VMX/VSX context switch, improved self tests, support for Nvlink NPUs, support for kexec on 476fpe, various other POWER9 updates, and a handful of other PowerPC updates.

Those interested in PowerPC on Linux can find all of the v4.5 details via this pull request that was sent in this morning by subsystem maintainer Michael Ellerman.
