Just as a heads-up: The current set of patches as they are present in the tgt-sh4 branch on git://github.com/rth7680/qemu.git are a HUGE improvement for qemu-sh4 user mode. Several packages which previously crashed during build or use can now be used properly! So, I hope to see this series merged

[Qemu-devel] [PATCH v2 08/27] linux-user/sh4: Notice gUSA regions during signal delivery

We translate gUSA regions atomically in a parallel context. But in a serial context a gUSA region may be interrupted. In that case, restart the region as the kernel would. Signed-off-by: Richard Henderson --- linux-user/signal.c | 23 +++ 1 file changed, 23
