[PATCH 0/5] fix bugs of x2apic/intr-remap

[Weidong Han]

interupt remapping was decoupled from x2apic already, but there are still
some issues, such as doesn't ack remapped interrupts correctly, and doesn't
remap ioapic interrupt when x2apic is not enabled.

This patchset fixes the ack for remapped interrupts, and alwasys enables
interrupt remapping before ioapic setup to guarantee ioapic interrupts are
remapped, adjusts the dependency of x2apic and interrupt remapping in
lapic_resume. In addition, add option "nointremap" to disable interrupt
remapping.

The patchset can be applied on linux head. Thanks.
