Thanks, Dan.  I'll use uint32 for r11 in my commit.

Do you have comments to arm_fps_group.patch, which fixes the 2nd problem
I pointed out in [1]?  In short, this fix will make GDB treat fps
register as registers in float group, fps will disappear in output of
"info register".

gdb/
	* arm-tdep.c (arm_register_reggroup_p): New.
	(arm_gdbarch_init): Set arm_register_reggroup_p for hook
	register_reggroup_p.

arm_fps_group.patch is the 2nd patch I attached in [1].
