actually useful (Randy Dunlap)
- Update maintainers entries for linux-arm-kernel to indicate it is
moderated for non-subscribers (Randy Dunlap)
- Move install rules to arch/arm/Makefile (Masahiro Yamada)
- Drop unnecessary ARCH_NR_GPIOS definition (Linus Walleij)
- Don't warn about atags_to_fdt() stack size (David Heidelberg)
- Speed up unaligned copy_{from,to}_kernel_nofault (Arnd Bergmann)
- Get rid of set_fs() usage (Arnd Bergmann)
- Remove checks for GCC prior to v4.6 (Geert Uytterhoeven)
