The nested SVM code emulates a #vmexit caused by a request to open the irq window right in the request function. This is a bug because the request function runs with preemption and interrupts disabled but the #vmexit emulation might sleep. This can cause a schedule()-while-atomic bug and is fixed with this patch. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
