iommupt: Add struct iommupt_pending_gather

Browse source

Add a struct to keep track of all the things that are pending to be
merged into the gather. The way gather merging works, the pending
range is checked against the current gather, and the current gather
can be flushed before the pending things are added.

Thus, if new things have to be recorded in the gather they need to be
kept in the pending struct until after the gather is optionally
flushed.

The next patch adds new items to the gather and the pending struct.
