 Modified Files:
 	src/sys/arch/x86/x86: pmap_tlb.c
 
 Log Message:
 Operation pmap_tlb_processpacket() uses x86_ipi(.., LAPIC_DEST_ALLEXCL, ...)
 when cpuset "target" equals "kcpuset_running".  During boot, while some CPUs
 are not running yet, this will result in more IPI interrupts than expected
 and "pmap_tlb_pendcount" related KASSERTs fire.
 
 Compare the cpuset "target" against "kcpuset_attached", as this set represents
 the CPUs LAPIC_DEST_ALLEXCL will notify.
 
 Should fix PR port-amd64/47437
