From 2c579042e3be50bb40a233a6986348b4f40ed026 Mon Sep 17 00:00:00 2001 From: Bharata B Rao Date: Thu, 12 May 2016 09:18:14 +0530 Subject: cpu: Add a sync version of cpu_remove() This sync API will be used by the CPU hotplug code to wait for the CPU to completely get removed before flagging the failure to the device_add command. Sync version of this call is needed to correctly recover from CPU realization failures when ->plug() handler fails.
