If anyone has any objections, please let me know. ------------------ From: Uros Bizjak [ Upstream commit a1855f1b7c33642c9f7a01991fb763342a312e9b ] percpu_base is used in various percpu functions that expect variable in __percpu address space. Correct the declaration of percpu_base to void __iomem * __percpu *percpu_base; to declare the variable as __percpu pointer. The patch fixes several sparse warnings: irq-gic.c:1172:44: warning: incorrect type in assignment (different address spaces) irq-gic.c:1172:44: expected void [noderef] __percpu *[noderef] __iomem *percpu_base irq-gic.c:1172:44: got void [noderef] __iomem *[noderef] __percpu * ... irq-gic.c:1231:43: warning: incorrect type in argument 1 (different address spaces) irq-gic.c:1231:43: expected void [noderef] __percpu *__pdata irq-gic.c:1231:43: got void [noderef] __percpu *[noderef] __iomem *percpu_base There were no changes in the resulting object files.
