[Qemu-devel] [PATCH v3 00/30] target/sh4 improvements

[Richard Henderson]

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.
