  "message": "powerpc: Make sure we copy all cpu_spec features except PMC related ones\n\nWhen identify_cpu() is called a second time with a logical PVR, it\nonly copies a subset of the cpu_spec fields so as to avoid overwriting\nthe performance monitor fields that were initialized based on the\nreal PVR.\n\nHowever some of the other, non performance monitor related fields are\nalso not copied:\n * pvr_mask\n * pvr_value\n * mmu_features\n * machine_check\n\nThe fact that pvr_mask is not copied can result in show_cpuinfo()\nshowing the cpu as \"unknown\", if we override an unknown PVR with a\nlogical one - as reported by Shaggy.\n\nSo change the logic to copy all fields, and then put back the PMC\nrelated ones in the case that we\u0027re overwriting a real PVR with a\nlogical one.\n\nSigned-off-by: Michael Ellerman \u003cmichael@ellerman.id.au\u003e\nAcked-by: Dave Kleikamp \u003cshaggy@linux.vnet.ibm.com\u003e\nSigned-off-by: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\n",
