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.
