On !RT the header file get_irq_regs() gets pulled in via other header files. On RT it does not and the build fails: drivers/hv/vmbus_drv.c:975 implicit declaration of function ‘get_irq_regs’ [-Werror=implicit-function-declaration] drivers/hv/hv.c:115 implicit declaration of function ‘get_irq_regs’ [-Werror=implicit-function-declaration] Add the header file for get_irq_regs() in a common header so it used by vmbus_drv.c by hv.c for their get_irq_regs() usage.
