[Qemu-devel] [RFC 0/3] Move notdirty handling to cputlb

[Richard Henderson <richard.henderson@linaro.org>]

RFC because this doesn't work, and I don't quite understand why.
The only failing test is {i386,x86_64} pxe-test -- the other
migration tests that use notdirty all pass.

Note that if you try to reproduce this on x86, you'll likely
have to --disable-kvm, as otherwise the pxe-test will skip tcg.

Anyone who knows how this works willing to have a look?
