+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+[ Upstream commit b9fcc1867cc7921bb8441be327ed58461ed12255 ]
+
+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.
