Subject: [PATCH] ARM: fixmap: make __end_of_early_ioremap_region an enum value

From: Arnd Bergmann <arnd@...db.de>

Building with W=1 shows warnings for the __end_of_fixed_addresses
definition:

    In file included from mm/early_ioremap.c:18:
    arch/arm/include/asm/fixmap.h:39:35: error: '__end_of_fixed_addresses' defined but not used [-Werror=unused-const-variable=]

Move the calculation slightly up in the file into the enum that
contains __end_of_fixmap_region and __end_of_early_ioremap_region.
