Subsystem:
kernel virtual machine for powerpc (kvm/powerpc), linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

From: Hollis Blanchard <redacted> Match only the first part of cur_cpu_spec->platform. 440GP (the first 440 processor) is identified by the string "ppc440gp", while all later 440 processors use simply "ppc440".
