How should I change the patch to make it proper? SA1111 is broken anyway:
config FORCE_MAX_ZONEORDER
int "Maximum zone order" if ARCH_SHMOBILE
range 11 64 if ARCH_SHMOBILE
default "9" if SA1111
default "11"
AFAIK if ARCH_SHMOBILE defines dependency on ARCH_SHMOBILE, so SA1111 won't be evaluated (at least if I select SA1111 include/generated/autoconf.h shows "11"). If I add SA1111 to dependency list like this:
depends on ARCH_SHMOBILE || SOC_AM33XX || SA1111
the prompt in "Kernel features" becomes visible, but it doesn't have the default value of "9", but "11".
Am I missing something?
