Unfortunately this means that I can not apply this and the following patch
until after the next commit window, which is unfortunate since patch 4
does not logically depend on patch 3. That also means that I can not apply
the last patch of the series since it depends on the ability to disable
write protect. Those patches will have to wait until after the next commit
window.
