[PATCH] x86-64: Use safe_apic_wait_icr_idle in __send_IPI_dest_field - x86_64
Use safe_apic_wait_icr_idle to check ICR idle bit if the vector is NMI_VECTOR to avoid potential hangups in the event of crash when kdump tries to stop the other CPUs. Signed-off-by: NFernando Luis Vazquez Cao <fernando@oss.ntt.co.jp> Signed-off-by: NAndi Kleen <ak@suse.de>
