Subject: [PATCH v3 12/14] sh: drop ranges for definition of ARCH_FORCE_MAX_ORDER

From: "Mike Rapoport (IBM)" <rppt@...nel.org>

sh defines insane ranges for ARCH_FORCE_MAX_ORDER allowing MAX_ORDER
up to 63, which implies maximal contiguous allocation size of 2^63
pages.

Drop bogus definitions of ranges for ARCH_FORCE_MAX_ORDER and leave it a
simple integer with sensible defaults.

Users that *really* need to change the value of ARCH_FORCE_MAX_ORDER
will be able to do so but they won't be mislead by the bogus ranges.
