Hi,
We do cross compile builds for ARC Linux. To avoid the env var set, we have a
defconfig entry for CONFIG_CROSS_COMPILE.
This worked fine so far (host gcc 4.4 i.e.). When switched to a new host distro
(gcc 4.7), a defconfig build spews out the warning.

The first 2 have been fixed in subsequent patches.
Due to the nature of the 750 and 770, it is not possible to build for
both together, w/o special runtime glue code which would hurt
performance.

PARISC defines /proc/sys/kernel/unaligned-trap to runtime toggle
unaligned access emulation.
The exact mechanics of enablig/disabling are still arch specific, we can
make the sysctl usable by other arches.

This is more natural and is now doable since the choice constructs are
gone.

st in case a platform has an obscure device
which say needs 0 based bus address.
That way no longer needs to unconditinally include
Also verfied that on Angel4 board, other peripherals (IDE-disk / EMAC)
work fine with 0x8000_ based dma addresses.

The population itself needs to be done pretty early, from init_early
callback.
