Thomas Gleixner 6758034e4d x86/process/64: Make save_fsgs_for_kvm() ready for FSGSBASE ... save_fsgs_for_kvm() is invoked via vcpu_enter_guest() kvm_x86_ops.prepare_guest_switch(vcpu) vmx_prepare_switch_to_guest() save_fsgs_for_kvm() with preemption disabled, but interrupts enabled. The upcoming FSGSBASE based GS safe needs interrupts to be disabled. This could be done in the helper function, but that function is also called from switch_to() which has interrupts disabled already. Disable interrupts inside save_fsgs_for_kvm() and rename the function to current_save_fsgs() so it can be invoked from other places.
