Version 1 of this series inadvertently dropped the "static" that limits the scope of gsi_channel_update(). Version 2 fixes this (in patch 3).
While reviewing the IPA NAPI polling code in detail I found two problems. This series fixes those, and implements a few other improvements to this part of the code.
The first two patches are minor bug fixes that avoid extra passes through the poll function. The third simplifies code inside the polling loop a bit.
The last two update how interrupts are disabled; previously it was possible for another I/O completion condition to be recorded before NAPI got scheduled.
