The big ticket item in this series is the support for
user-space atomics.  But a lot of other cleanup has
crept in as well.

Changes since v2 incorporate feedback from Aurelien.
I've tried to remember to add individual changelogs
to the patches, but I may have forgotten some.

I do now include the linux-user reserved_va changes
that I posted subsequent to posting v2.

I believe there are only 4 patches that have not 
seen a Reviewed-by yet.

Thanks for this new version. I have applied patches 2-27 to my tree. I
believe the patch 1 doesn't provide the correct (corner case) behaviour
in system mode. As for the last 3 patches, given they touch non-sh4
specific part of linux-user, I guess they should at least be acked by
a linux-user maintainer.
