[GIT PULL v2] nommu fixes for 3.17-rc1

[Uwe Kleine-König]

Hello Russell,

I updated my tag to pull to not include the commit that drops ARM740T,
ARM940T and ARM946E-S because of Arnd's concerns. Also the two cleanups
that depended on this one are dropped.

(As before) I picked -rc3 as base because 1c2f87c22566..6980c3e2514e~ is
broken on nommu. 

The following changes since commit 4c834452aad01531db949414f94f817a86348d59:

  Linux 3.16-rc3 (2014-06-29 14:11:36 -0700)

  ARM: make user_addr_max more robust (2014-07-01 11:12:09 +0200)

----------------------------------------------------------------
Two different fixes for the same problem making some ARM nommu configurations
not boot since 3.6-rc1. The problem is that user_addr_max returned the biggest
available RAM address which makes some copy_from_user variants fail to read
from XIP memory.

Even in the presence of one of the two fixes the other still makes sense, so
both patches are included here.

This problem was the last one preventing efm32 boot to a prompt with mainline.
