If we do a userspace access from kernel mode, and get a
data access exception, we need to check the exception
table just like a normal fault does.
The spitfire DAX handler was doing this, but such logic
was missing from the sun4v DAX code.

People keep on doing

testing it only on x86_64 and this generates a warning storm on
powerpc, sparc64, etc. Because they use `long', not `long long'.
Quite a few 64-bit architectures are using `long' for their
s64/u64 types. We should convert them all to `long long'.
Update types.h so we use unsigned long long for u64 and
fix all warnings in sparc64 code.
Tested with an allnoconfig, defconfig and allmodconfig builds.
This patch introduces additional warnings in several drivers.
These will be dealt with in separate patches.

o Move all files from sparc64/kernel/ to sparc/kernel
- rename as appropriate
o Update sparc/Makefile to the changes
o Update sparc/kernel/Makefile to include the sparc64 files
NOTE: This commit changes link order on sparc64!
Link order had to change for either of sparc32 and sparc64.
And assuming sparc64 see more testing than sparc32 change link
order on sparc64 where issues will be caught faster.
