Subject: linux/master crashes on boot with KASAN=y

Hi!

I bisected a crash on boot to this:

commit 21506525fb8ddb0342f2a2370812d47f6a1f3833 (HEAD, refs/bisect/bad)
Author: Andy Lutomirski <luto@...nel.org>
Date:   Mon Dec 4 15:07:16 2017 +0100

    x86/kasan/64: Teach KASAN about the cpu_entry_area
    
    The cpu_entry_area will contain stacks.  Make sure that KASAN has
    appropriate shadow mappings for them.
