x86, intel-iommu: fix X2APIC && !ACPI build failure
This build failure: | drivers/pci/dmar.c:47: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘dmar_tbl_size’ | drivers/pci/dmar.c:62: warning: ‘struct acpi_dmar_device_scope’ declared inside parameter list | drivers/pci/dmar.c:62: warning: its scope is only this definition or declaration, which is probably not what you want Triggers due to this commit: d0b03bd: x2apic/intr-remap: decouple interrupt remapping from x2apic Which exposed a pre-existing but dormant fragility of the 'select X86_X2APIC' it moved around and turned that fragility into a build failure. Replace it with a proper 'depends on' construct.

---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.
