Subject: mm: fix broken gfp_zone with __GFP_THISNODE
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8cece85ec744bdc7ea0fc2d33f65b3f031c28468;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

mm: fix broken gfp_zone with __GFP_THISNODE

This hack, "base = MAX_NR_ZONES", at __GFP_THISNODE was used for old
zonliests.

Now, new zonelist[] have a list for __GFP_THISNODE and this hack is incorrect.
Should be removed.
