Merge branch 'net-ipa-support-compile_test'

Alex Elder says:

====================
net: ipa: support COMPILE_TEST

This series adds the IPA driver as a possible target when
the COMPILE_TEST configuration is enabled.  Two small changes to
dependent subsystems needed to be made for this to work.

Version 2 of this series adds one more patch, which adds the
declation of struct page to "gsi_trans.h".  The Intel kernel test
robot reported that this was a problem for the alpha build.
