[Xen-devel] [PATCH] some cleanups and fixes to VT-d Interrupt Remapping and x2APICc.

["Cui, Dexuan" <dexuan.cui@xxxxxxxxx>]

001.patch 
        vt-d: replace the gdprintk with dprintk since it isn't in guest context.

002.patch 
        Some cleanups for apic_write, apic_read, apic_wrmsr, apic_rdmsr.

003.patch 
        vt-d: some small fixes to apic_pin_2_ir_idx.

004.patch
        vt-d: don't treat IOAPIC RTE of dest_SMI type specially.

        We also need to create IRTE for it since we enable EIM and clear CFI, 
or else,
        the IOAPIC RTE's interrupt message would be blocked by IR unit.

        In io_apic_read_remap_rte(), we now use 
"apic_pin_2_ir_idx[apic][ioapic_pin]"
        rather than "(remap_rte->index_15 << 15) | remap_rte->index_0_14" to 
avoid the
        "interrupt remapping table out of bound error".

Thanks,
-- Dexuan
