From: Stijn Tintel Date: Wed, 3 Nov 2021 18:00:26 +0000 (+0200) Subject: kernel: add missing KASAN config symbols X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ec68c75c629eed149ed4416d5300328deb53a417;p=openwrt%2Fstaging%2Fthess.git kernel: add missing KASAN config symbols Enabling KERNEL_KASAN exposes several missing symbols. As KASAN_SW_TAGS is only implemented for arm64 CPUs and requires clang, it doesn't make sense to make this a build option so just default to KASAN_GENERIC and disable KASAN_SW_TAGS. While at it, disable TEST_KASAN_MODULE in the generic 5.10 config. Fixes build failures with KERNEL_KASAN enabled.
