 config X86_X2APIC
         bool "Support x2apic"
-        depends on X86_LOCAL_APIC && X86_64
-        select INTR_REMAP

         ---help---
           This enables x2apic support on CPUs that have this feature.
 
           This allows 32-bit apic IDs (so it can support very large systems),
           and accesses the local apic via MSRs not via mmio.
 
-          ( On certain CPU models you may need to enable INTR_REMAP too,
-            to get functional x2apic mode. )
-
           If you don't know what to do here, say N.
