[RFC PATCH V2] x86: call smp vmxoff in smp stop

2017-01-04 Thread Xishi Qiu
From: f00186668 We need to disable VMX on all CPUs before stop cpu when OS panic, otherwisewe risk hanging up the machine, because the CPU ignore INIT signals when VMX is enabled. In kernel mainline this issue existence. Signed-off-by: f00186668 --- arch/x86/kernel/smp.c | 3 +++ 1 file change
