Re: [patch] x86_64, irq: check remote IRR bit before migrating level triggered irq

[Yinghai Lu]

Eric,

ioapic_level irq is limited, So if we keep vector number not changed
when imgration to other cpus.  It that could help.

it will need modify a little with assign_irq_vector and
irq_complete_move/smp_irq_move_cleanup_interrupt. because it assume
vector must be changed.
