[Xen-devel] [PATCH v2 for-4.9 0/7] x86/emul: Userspace fuzzing harness fixes



This is a subset of the previous fuzzing bugfix/improvement series, which is
the minimum required to avoid hitting assertions in the emulator.

From a 4.9 point of view, this entirely userspace testing harness changes (so
safe to take), but it allows us to sensibly fuzz the emulator in the
hypervisor (rather than hitting a load of assertions).

Andrew Cooper (7):
  MAINTAINERS: Move the x86 instruction emulator under x86 maintainership
  tools/insn-fuzz: Don't hit memcpy() for zero-length reads
  tools/insn-fuzz: Avoid making use of static data
  tools/insn-fuzz: Fix a stability bug in afl-clang-fast mode
  tools/insn-fuzz: Correct hook prototypes, and assert() appropriate segments
  tools/insn-fuzz: Provide IA32_DEBUGCTL consistently to the emulator
  tools/insn-fuzz: Fix assertion failures in x86_emulate_wrapper()
