[OpenWrt-Devel] [PATCH 1/2] octeon: Deactivate MIPS O32 and N32 support

Sun May 12 11:21:22 EDT 2019

OpenWrt is completely compiled from sources using a 64 bit compiler, we
do not need support for the old 32 bit MIPS interface on 64 Bit CPUs,
deactivate it.

Fixes: 46af22de16b2 ("kernel: Remove CONFIG_COMPAT")
