Sure on "Shadow Stack". For Write=0,Dirty=1 there was a previous
suggestion to standardize on how these bits are referred to across the
series in both the comments and commit logs. I think the capitalization
helps differentiate between the concepts of write and dirty and the
actual PTE bits with those names. Especially since shadow stack muddies
the concepts of writable and dirty memory, I thought it was a helpful
distinction. Is it ok?

The other suggestions seem good.

Thanks,
