[PATCH v5 2/6] kasan: Add KASAN mode kernel parameter

2021-01-21 Thread Vincenzo Frascino
Architectures supported by KASAN_HW_TAGS can provide a sync or async mode of execution. On an MTE enabled arm64 hw for example this can be identified with the synchronous or asynchronous tagging mode of execution. In synchronous mode, an exception is triggered if a tag check fault occurs. In
