Description Andrey Konovalov 2021-02-15 18:58:45 UTC 
Add HW_TAGS support for tagging and checking stack variables.

Both generic and SW_TAGS KASAN modes already support that.

The implementation of stack tagging support has to work with a single kernel image on devices with and without MTE support. This is demanded by Android Generic Kernel Image.
