in [Kernel]

From: Stefano Stabellini on 24 May 2010 14:40 Hi all, this is another update of the PV on HVM Xen series that addresses Jeremy's comments. The platform_pci hooks have been removed, suspend/resume for HVM domains is now much more similar to the PV case and shares the same do_suspend function. Alloc_xen_mmio_hook has been removed has well, now the memory allocation for the grant table is done by the xen platform pci driver directly. The per_cpu xen_vcpu variable is set by a cpu_notifier function so that secondary vcpus have the variable set correctly no matter what the xen features are on the host. The kernel command line option xen_unplug has been renamed to xen_emul_unplug and the code that makes use of it has been moved to a separate file (arch/x86/xen/platform-pci-unplug.c). Xen_unplug_emulated_devices is now able to detect if blkfront, netfront and the Xen platform PCI driver have been compiled, and set the default value of xen_emul_unplug accordingly. The patch "Initialize xenbus device structs with ENODEV as default" has been removed from the series and it will be sent separately. Finally the comments on most of the patches have been improved. The series is based on 2.6.34 and supports Xen PV frontends running in a HVM domain, including netfront, blkfront and the VIRQ_TIMER. In order to be able to use VIRQ_TIMER and to improve performances you need a patch to Xen to implement the vector callback mechanism for event channel delivery. A git tree is also available here: git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git branch name 2.6.34-pvhvm-v2.
