[PATCH 2/3] x86/smpboot: Allow making an INIT IPI conditional

2021-01-15 Thread Andrew Cooper
A subsequent change is going to introduce SKINIT support, wherein the APs will be already be in the wait-for-SIPI state, and an INIT must not be sent. Introduce a send_INIT boolean, so we can control sending an INIT IPI separately from sending SIPIs. No functional change. Signed-off-by: Andrew C
