The Cyrix CPU specific MTRR function cyrix_set_all() will never be
called, as the struct mtrr_ops set_all() callback will only be called
in the use_intel() case, which would require the use_intel_if member
of struct mtrr_ops to be set, which isn't the case for Cyrix.
Note that this patch has already been applied to tip.git.
