You have an accidental submodule change in here. (It probably crept
in on a rebase -- git's terrible submodule handling makes that very
easy to do by accident.)

I've removed that and applied these changes to target-arm.next;
thanks.

...the linux-user target fails to build, though:

/usr/bin/ld: libqemu-arm-linux-user.fa.p/target_arm_gdbstub.c.o: in
function `arm_gdb_get_m_secextreg':
gdbstub.c:(.text+0x41cd): undefined reference to `arm_v7m_get_sp_ptr'

Could you have a look at that, please?

thanks
