Re: Re: [Bug 350] New: i386 context switch very slow compared to 2.4 due to wrmsr (performance)

BTW, why is sysenter supposed to be disabled while in vm86? And if it should be disabled (as now in sys_vm86), the next context switch back to the vm86 process re-enables it, in load_esp0, right? So what's the gain?
