Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue
Tony Nguyen says: ==================== 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. ==================== Signed-off-by: David S.
