[PATCH v2] powerpc: Add POWER9 architected mode to cputable

From: Russell Currey <hidden>
Date: 2017-02-17 02:01:47
Subsystem: linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

PVR value of 0x0F000005 means we are arch v3.00 compliant (i.e. POWER9).
