Subject: get_unmapped_area handles MAP_FIXED on arm
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=acec0ac0a87ca821f9d204780c2d1aa0509a6346;p=openwrt%2Fstaging%2Fblogic.git

get_unmapped_area handles MAP_FIXED on arm

ARM already had a case for MAP_FIXED in arch_get_unmapped_area() though it was
not called before.  Fix the comment to reflect that it will now be called.
