From 2654ace151c07bd6519a7b71ab98d763137302eb Mon Sep 17 00:00:00 2001 From: Tom Lendacky Date: Mon, 16 Nov 2020 11:02:20 -0600 Subject: kvm/i386: Set proper nested state format for SVM Currently, the nested state format is hardcoded to VMX. This will result in kvm_put_nested_state() returning an error because the KVM SVM support checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a result, kvm_arch_put_registers() errors out early. Update the setting of the format based on the virtualization feature: VMX - KVM_STATE_NESTED_FORMAT_VMX SVM - KVM_STATE_NESTED_FORMAT_SVM Also, fix the code formatting while at it.
