[PATCH] x86_64: x86_86 msi miss one entry handler

Browse Source 
In x86_64 architecture, if device driver with msi function
gets 0xee vector by assign_irq_vector() function, system will
crash if this interrupt happens. It is because 0xee interrupt
entry is empty. This patch modifies this. This patch is based
on 2.6.17-rc6.
