LCBB is supposed to overwrite only the bottom 32 bits, but QEMU
erroneously overwrites the entire register.

Currently single-stepping SVC executes two instructions. The reason is
that EXCP_DEBUG for the SVC instruction itself is masked by EXCP_SVC.
Fix by re-raising EXCP_DEBUG.

The ipmi-bt-test uses "-device ipmi-bmc-extern", thus it should
only be run if this device has been enabled in the configuration.

Booting a Linux kernel with the malta machine is currently broken
on big endian hosts. The cpu_to_gt32 macro wants to byteswap a value
for little endian targets only, but uses the wrong way to do this:
cpu_to_[lb]e32 works the other way round on big endian hosts! Fix
it by using the same ways on both, big and little endian hosts.

To: qemu-devel, Richard Henderson; +Cc: Ilya Leoshkevich, David Hildenbrand
From: Ilya Leoshkevich <iii@linux.ibm.com>
In qemu-user-s390x, /proc/cpuinfo contains:
processor 0: version = 00, identification = 000000, machine = 8561
processor 1: version = 00, identification = 400000, machine = 8561
The highest nibble is supposed to contain the CPU address, but it's off
by 2 bits. Fix the shift value and provide a symbolic constant for it.
With the fix we get:
processor 0: version = 00, identification = 000000, machine = 8561
processor 1: version = 00, identification = 100000, machine = 8561
Fixes: 076d4d39b65f ("s390x/cpumodel: wire up cpu type + id for TCG")

Some s390x userspace programs are confused when seeing a foreign

kernel code structure where possible.
Output example:

bogomips per cpu: 13370.00
max thread id : 0
features : esan3 zarch stfle msa

processor 0: version = 00, identification = 000000, machine = 8561
processor 1: version = 00, identification = 100000, machine = 8561
