Merge branch 'net-ll_temac-x86_64-support'

Esben Haabendal says:

====================
net: ll_temac: x86_64 support

This patch series adds support for use of ll_temac driver with
platform_data configuration and fixes endianess and 64-bit problems so
that it can be used on x86_64 platform.

A few bugfixes are also included.

Changes since v2:
  - Fixed lp->indirect_mutex initialization regression for OF
    platforms introduced in v2

Changes since v1:
  - Make indirect_mutex specification mandatory when using platform_data
  - Move header to include/linux/platform_data
  - Enable COMPILE_TEST for XILINX_LL_TEMAC
  - Rebased to v5.1-rc7
