      x86: smap: new testcase · fa6318d1

      Test various combinations of the AC bit and reading/writing into
      user pages at CPL=0.
      
      One notable missing test is implicit kernel reads and writes (e.g.
      reading the IDT/GDT/LDT/TSS).  The interesting part of this is that
      AC must be ignored in ring 3; the processor always behaves as if AC=0.
      I skipped this because QEMU doesn't emulate this correctly, and because
      right now there's no kvm-unit-tests infrastructure to run code in ring
      3 at all.
