Hi tglx,
Thanks for the quick detailed

Hi,
Recently, two Hyper-V specific vectors were introduced in
arch/x86/include/asm/irq_vectors.h:
#if IS_ENABLED(CONFIG_HYPERV)
#define HYPERV_REENLIGHTENMENT_VECTOR 0xee
#define HYPERV_STIMER0_VECTOR 0xed
#endif
What if we need more such vectors on Hyper-V? This static global reserva
