[Arm-dev] supported 64bit hardware

[Lomovtsev, Vadim]

Hi Uli,

The patch sets UTS_MACHINE for arm64 is in the mainline already (4.9 has it for sure).
You may need to backport it onto your source tree.
:)

However, second one (which adds image_name rule into Makefile) needs more work to be done for other architectures and mkspec/builddep scripts also.
I plan get back to it after NY holydays.

WBR,
Vadim

Tank you very much! I was able to get rpms as well (even with CONFIG_LOCALVERSION_AUTO enabled)

You can find them for download here:

This is the patch I've applied, I'll try to get it merged into the upstream repo.

Cheers
Uli
