[kvm-unit-tests PATCH 4/4] lib: s390x: Split SIE fw structs from lib structs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The SIE control block is huge and takes up too much space.

Additionally sie.h will now only contain sie lib structs and
declarations so we have a clear divide about which header contains
which things.
