Option iommu=1 causes hypervisor to start debugger
Hi,
In changeset 19130:c8962b24fb50, when using iommu=1, it goes into the
hypervisor debugger. Why is this so? Thanks.
-Alex

[PATCH 2/3] xen: make direct versions of irq_enable/disable/save/restore to common code
Now that x86-64 has directly accessible percpu variables, it can also
implement the direct versions of these operations, which operate on a
vcpu_info structure directly embedded in the percpu area.
In fact, the 64-bit versions are more or less identical, and so can be
shared. The only two differences are:
1. xen_restore_fl_direct takes its argument in eax on 32-bit, and rdi on 64-bit.
