Re: [patch V2 00/46] x86, PCI, XEN, genirq ...: Prepare for device MSI

Hi Thomas,

The whole lot is also available from git:

   git://git.kernel.org/pub/scm/linux/kernel/git/tglx/devel.git device-msi

This has been tested on Intel/AMD/KVM but lacks testing on:

    - HYPERV (-ENODEV)

FWIW, I did a build and boot test in a hyperv guest with your
development branch, the latest commit is 71cbf478eb6f ("irqchip: Add
IMS (Interrupt Message Storm) driver - NOT FOR MERGING"). And everything
seemed working fine.

If you want me to set/unset a particular CONFIG option or run some
command for testing purposes, please let me know ;-)

    - VMD enabled systems (-ENODEV)
    - XEN (-ENOCLUE)
    - IMS (-ENODEV)

    - Any non-X86 code which might depend on the broken compose MSI message
      logic. Marc excpects not much fallout, but agrees that we need to fix
      it anyway.

#1 - #3 should be applied unconditionally for obvious reasons
#4 - #6 are wortwhile cleanups which should be done independent of device MSI

#7 - #8 look promising to cleanup the platform MSI implementation
     	independent of #8, but I neither had cycles nor the stomach to
     	tackle that.

#9	is obviously just for the folks interested in IMS

Thanks,
