The function do_sigreturn() tries to store the PC, NPC and PSR in uint32_t local variables, which implicitly drops the high half of these fields for 64-bit guests. The usual effect was that a guest which used signals would crash on return from a signal unless it was lucky enough to take it while the PC was in the low 4GB of the address space. In particular, Debian /bin/dash and /bin/bash would segfault after executing external commands. Use abi_ulong, which is the type these fields all have in the __siginfo_t struct.
