charset="utf-8" The rtc-reset-reinjection QMP command is specific to x86, other boards do n= ot have the ACK tracking functionality that is needed for RTC interrupt reinjection. Therefore the QMP command is only included in x86, but qmp_rtc_reset_reinjection() is implemented by hw/rtc/mc146818rtc.c and requires tracking of all created RTC devices. Move the implementation to hw/i386, so that 1) it is available even if no RTC device exist 2) the only RTC that exists is easily found in x86ms->rtc.
