The code you move doesn't look to be x86 specific in the sense that
it makes no sense on other architectures, but just because certain
pieces are missing on Arm. With this I question whether is it really
appropriate to move this code. I do realize that in similar earlier
cases my questioning was mostly ignored ...
There are no plan to get support for PIRQ on Arm. All the interrupts
will be properly sent to the guest using a virtual interrupt controller.
Regarding the code itself, there are still a few bits that are x86
specific (see struct dev_intx_gsi_link). So I think the right action
for now is to move the code to an x86 directory.
This can be adjusted in the future if there is another architecture that
would require to use PIRQ.
