From cfedf08b0c09f325fa24d91e8c9433ec481800cf Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Sun, 20 Sep 2015 14:45:37 +0300 Subject: xtensa: nommu: fix USER_RING definition There's no kernel/user separation in noMMU and PS.RING may not exist. Even if it exists it should not be used because TLB entries are not set up for user ring on user pages.
