Subject: mips: drop ranges for definition of ARCH_FORCE_MAX_ORDER
Date: Wed, 22 Mar 2023 10:15:20 +0200
MIPS 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.
