I do see the PSW_L issue as well (32-bit machine when starting HP-UX 11).
When leaving out patches 42-45 ("target/hppa: Implement PSW_T" and followi=
ng)
I can boot 32-bit HP-UX 10 and 11.

Will review the patches now individually, but maybe you should
push the patches 1-41 first and we take the PSWT/L patches later?
