[Qemu-devel] [PATCH v5 00/14] xics: reworks and in-kernel support

[Alexey Kardashevskiy]

Yet another try with XICS and XICS-KVM.

v4->v5:
Rebased onto upstream;
Put few "reviewed-by: Andreas";
Added IRQFD enablement patches.

v3->v4:
Addressed multiple comments from Alex;
Split out many tiny patches to make them easier to review;
Fixed xics_cpu_setup not to call the parent;
And many, many small changes.

v2->v3:
Addressed multiple comments from Andreas;
Added 2 patches for XICS from Ben - I included them into the series as they
are about XICS and they won't rebase automatically if moved before XICS rework
so it seemed to me that it would be better to carry them toghether. If it is
wrong, please let me know, I'll repost them separately.

v1->v2:
The main change is this adds "xics-common" parent for emulated XICS and 
XICS-KVM.
And many, many small changes, mostly to address Andreas comments.

Migration from XICS to XICS-KVM and vice versa still works.
