[Mukesh R <mrathor@linux.microsoft.com>]

This patch series implements interrupt remapping part of the PCI
passthru feature on Hyper-V when Linux is running as a privileged VM.
These patches complement Part I of the feature at:

https://lore.kernel.org/linux-hyperv/20260512020259.1678627-1-mrathor@linux.microsoft.com/T/#t

Testing and other details are listed there.

Changes in V1:
 o rebase to above V3 of Part I
 o check for NULL irqdata->parent_data->chip before calling 
   irq_chip_unmask_parent().

Thanks,
-Mukesh
