      hexagon:defconfig fails to build in linux-next since commit 332fd7c4
      ("genirq: Generic chip: Change irq_reg_{readl,writel} arguments").
      
      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 <linux/io.h> from <linux/irq.h>,
      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.
