From 06210b42f33ea1c29a90f4db2d88be91c511154b Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Sat, 1 Aug 2015 16:08:05 -0700 Subject: Drivers: hv: vmbus: remove hv_synic_free_cpu() call from hv_synic_cleanup() We already have hv_synic_free() which frees all per-cpu pages for all CPUs, let's remove the hv_synic_free_cpu() call from hv_synic_cleanup() so it will be possible to do separate cleanup (writing to MSRs) and final freeing. This is going to be used to assist kexec. Signed-off-by: Vitaly Kuznetsov Signed-off-by: K. Y.
