|
|
Let's rename PSW_MASK_ESA_ADDR to PSW_MASK_SHORT_ADDR because we're
|
||
|
|
not working with a ESA PSW which would not support the extended
|
||
|
|
addressing bit. Also let's actually use it.
|
||
|
|
|
||
|
|
Additionally we introduce PSW_MASK_SHORT_CTRL and use it throughout
|
||
|
|
the codebase.
