[patch] ia64 vcpu_reset() do not call kmalloc() with irqs disabled

[Jes Sorensen <jes@xxxxxxx>]

Hi,

Here we go again, another case where we were calling kmalloc() through
vcpu_reset() while local interrupts were disabled.

Cheers,
Jes

Restore local irq enabled state before calling kvm_arch_vcpu_init(),
which calls kmalloc(GFP_KERNEL).
