Hi Thomas,
It looks you removed GENERIC_IRQ_SHOW by accident?

I got this build error:
...
LD vmlinux.o
MODPOST vmlinux.o
fs/proc/interrupts.o:(.rodata+0x118): undefined reference to `show_interrupts'
Makefile:1000: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

Adding GENERIC_IRQ_SHOW back can fix the build failure, and with the
pachset Hyper-V PCI pass-through can work fine.

Thanks,
-- Dexuan
