Support for selective use of 4 KiB page tables on IBM z Systems
This update adds the option `--s390-pgste` to the *ld* linker from the _binutils_ package to mark applications for the IBM z Systems architecture that require 4 KiB memory page tables on the lowest level. As a result, use of this feature can be restricted only to applications that need it, allowing optimal use of space by all applications on the system. Note that the *qemu* backend no longer forces 4 KiB lowest level page tables on all running applications. Make sure to specify the new option if your applications require them.
