...ed vCPUs waiting on that lock. This irq should always be disabled. However, when Dom0 is shuting down, function fixup_irqs is called which unmasks all irqs. Function unmask_irq effectively re-enables lock_kicker_irq and its irq handler is invoked which reports bug and crashes Dom0. This patch sets IRQ_PER_CPU flag in irq desc and excludes percpu IRQs from being fixed up when taking CPUs down.

Hi. This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset does the followings. - Some preparation work. Mainly importing header files to define related structures. - Then, define functions related to hypercall which is the way to communicate with Xen hypervisor. - Add some helper functions which is necessary to

Hi. This patchset is ia64/xen domU patch take 8 which was updated following Tony's review. (Thank you very much, Tony.) This patchset implements ia64/xen domU support based on ia64/pv_ops frame work which was sent as another patchest. This patchset is for linux ia64 test branch and depends on some patches for xen common part I'll send separately. To compile, the changesets in x86/xen

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it
