Subject: KVM: s390: add and extend interrupt information data structs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=81aa8efe0190cf5bf7eaafb57341cd7d0aea96cd;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

KVM: s390: add and extend interrupt information data structs

With the currently available struct kvm_s390_interrupt it is not possible to
inject every kind of interrupt as defined in the z/Architecture. Add
additional interruption parameters to the structures and move it to kvm.h
