[Xen-devel] [PATCH v2 00/12] fuzz: update x86emul fuzzer

[Wei Liu <wei.liu2@xxxxxxxxxx>]

The first few patches refactor x86emul code so that more code can be shared
between xen and userspace tools.

I have run XTF suite (tests subject to availability on the testbox I use, and
xsa-195 was skipped because qemu segfault -- a known issue) against this
series, no issue is found.

Wei.
