    x86/cpu/intel: Remove not needed paravirt_enabled() use for F00F work around · fa392794
    Luis R. Rodriguez 提交于
    The X86_BUG_F00F work around is responsible for fixing up the error
    generated on attempted F00F exploitation from an OOPS to a SIGILL.
    
    There is no reason why this code should not be allowed to run on
    PV guest on a F00F-affected CPU -- it would simply never trigger.
    The pv_enabled() check was there only to avoid printing the f00f
    workaround, so removing the check is purely a cosmetic change.
