It seems we can get away with dropping '__visible' and '__irq_entry' qualifiers from 'hyperv_reenlightenment_intr' declaration in mshyperv.h while keeping them in hv_init.c for the implementation. This way we can avoid the nasty 'no previous prototype' warning and not have to add '#include <linux/interrupt.h>' to mshyperv.h breaking vdso. I'm inclined to go ahead with this in v4 if nobody objects. -- Vitaly
