treewide: use PHYS_ADDR_MAX to avoid type casting ULLONG_MAX
With PHYS_ADDR_MAX there is now a type safe variant for all bits set. Make use of it. Patch created using a semantic patch as follows: // <smpl> @@ typedef phys_addr_t; @@ -(phys_addr_t)ULLONG_MAX +PHYS_ADDR_MAX // </smpl> Link: http://lkml.kernel.org/r/20180419214204.19322-1-stefan@agner.ch Signed-off-by: Stefan Agner <stefan@agner.ch> Reviewed-by: Andrew Morton <akpm@linux-foundation.org> Acked-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Catalin Marinas <catalin.marinas@arm.com> [arm64] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
