[PATCH] x86_64: Rename the extended cpuid level field
It was confusingly named. Signed-off-by: Andi Kleen <ak@suse.de> DESC x86_64: Switch SMP bootup over to new CPU hotplug state machine EDESC From: "Andi Kleen" <ak@suse.de> This will allow hotplug CPU in the future and in general cleans up a lot of crufty code. It also should plug some races that the old hackish way introduces. Remove one old race workaround in NMI watchdog setup that is not needed anymore. I removed the old total sum of bogomips reporting code. The brag value of BogoMips has been greatly devalued in the last years on the open market. Real CPU hotplug will need some more work, but the infrastructure for it is there now. One drawback: the new TSC sync algorithm is less accurate than before. The old way of zeroing TSCs is too intrusive to do later. Instead the TSC of the BP is duplicated now, which is less accurate.
