[PATCH 00/14] AArch64 BE Support

[Matthew Leach]

Hello,

This patch series adds big-endian support to the arm64 kernel. It has
been tested successfully with LTP on both AArch32 and AArch64
userspace configurations. There were no regressions reported over a
little-endian system.

The first patch (from Mark Rutland) clarifies the booting
requirements, which is needed for a big-endian kernel boot. The bulk
of the patches fix up issues in the architectural port, with the last
patch fixing an endianness assumption in the smc91x network driver.

Whilst there is another series of BE patches currently on the list:

  http://lists.infradead.org/pipermail/linux-arm-kernel/2013-October/204031.html

we believe that our work is both more complete and has been subjected
to substantial testing effort.

All comments welcome,

Matt
