Hi,
So here we go, trying to catch up on the PCI passthrough patch revision
number, here's v5 of the struct vcpu_info patch.
In the end I decided to merge the contents of struct vcpu_info directly
into CPU_COMMON as it was silly to create new files just to remove them
in the next patch again.
This boots for me on ia64 and builds on x86_64, obviously it is 100%
perfect <tm>!
Comments, bug reports, or upstream merge, welcome :-)
Cheers,
Jes
Merge vcpu_info into CPUState.
Move contents of struct vcpu_info directly into CPU_COMMON. Rename
struct qemu_kvm_work_item to qemu_work_item as it really isn't KVM
specific.
This eliminates the ugly static sized array of struct vcpu_info.
