...so given that, what we want on the QEMU side is:
 * in a migration preload function:
   /* if the sre_el1 subsection is not transferred this
    * means SRE_EL1 is 0x7 (which might not be the same as
    * our reset value).
    */
   cs->icc_sre_el1 = 0x7;

 * the reg_needed function should be
   return cs->icc_sre_el1 != 0x7;

and the rest of this patch is OK I think.

thanks
