====================
intel: use bitfield operations
Jesse Brandeburg says:
After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET(). It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.
This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.
Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.
The second patch just adds all the new #includes in one go.
The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.
The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.
