The primary build failure is arch/hexagon/include/asm/cacheflush.h: In function 'copy_to_user_page': arch/hexagon/include/asm/cacheflush.h:89:22: error: 'VM_EXEC' undeclared This is the result of including of from , which is now necessary due to the use of readl and writel from irq.h. This causes recursive inclusions in hexagon code; cacheflush.h is included from mm.h prior to the definition of VM_EXEC. Fix the problem by moving copy_to_user_page from the hexagon include file to arch/hexagon/mm/cache.c, similar to other architectures. After this change, several redefinitions of readl and writel are reported. Those are caused by recursive inclusions of io.h and asm/cacheflush.h. Fix those problems by reducing the number of files included from those files. Also, it was necessary to stop including asm-generic/cacheflush.h from asm/cacheflush.h. Instead, functionality originally provided by asm-generic/cacheflush.h is now coded in asm/cacheflush.h directly.
