[PATCH 00/35] kasan: add hardware tag-based mode for arm64

What does one need to do to enable MTE in the kernel?  I am trying to 
color some kernel module data, but when I call mte_get_mem_tag after 
calling mte_set_mem_tag_range, I get an invalid value.  I have assured 
that mte_assign_mem_tag_range has been called in mte_set_mem_tag_range, 
so the initial sanity checks pass.  Thanks.
