    i386: Allow KVM on i386 nonpae · 2d9ce177

    Currently, CONFIG_X86_CMPXCHG64 both enables boot-time checking of
    the cmpxchg64b feature and enables compilation of the set_64bit() family.
    Since the option is dependent on PAE, and since KVM depends on set_64bit(),
    this effectively disables KVM on i386 nopae.
    
    Simplify by removing the config option altogether: the boot check is made
    dependent on CONFIG_X86_PAE directly, and the set_64bit() family is exposed
    without constraints.  It is up to users to check for the feature flag (KVM
    does not as virtualiation extensions imply its existence).
