From 469b8ad283d748648960e2260a4a3c415b1b3956 Mon Sep 17 00:00:00 2001 From: Tang Chen Date: Wed, 28 Jan 2015 15:45:38 +0800 Subject: [PATCH] acpi, ich9: Add hotunplug request cb for ich9. Memory and CPU hot unplug are both asynchronous procedures. They both need unplug request cb when the unplug operation happens. This patch adds hotunplug request cb for ich9, and memory and CPU hot unplug will share it. Reviewed-by: Igor Mammedov Signed-off-by: Tang Chen Signed-off-by: Zhu Guihua Reviewed-by: Michael S.
