[PATCH v2 0/1] target/s390x: Allow 2G hugepages guest backing

Posted by Claudio Imbrenda 2 months ago

Allow mapping guest with 2G hugepages on hosts that support it.
    
Add new helper functions to check whether hpages are in effect, and
which size.

v1->v2:
* Rename the global variable to cap_hpage
* Use different values of cap_hpage to distinguish between hpage sizes
* Add wrappers to test for specific hpage sizes
