Subject: get_unmapped_area handles MAP_FIXED on arm
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=acec0ac0a87ca821f9d204780c2d1aa0509a6346;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.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.
