S/390: idte/ipte fixes
|
||
|
|
|
||
|
|
Later CPU generations added optional operands to the ipte/idte
|
||
|
|
instructions. I've added these with:
|
||
|
|
https://sourceware.org/ml/binutils/2017-05/msg00316.html ... but
|
||
|
|
supported the optional operands only with the specific hardware
|
||
|
|
levels. However, it is more useful to have the optional operands
|
||
|
|
already in the first versions. Of course they need to be zero there.
|
||
|
|
|
||
|
|
Regression-tested with on s390 and s390x. Committed to mainline.
