Subject: KVM: add hypercall nr to kvm_run
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=519ef35341b4f360f072ea74e398b70a5a2fc270;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

KVM: add hypercall nr to kvm_run

Add the hypercall number to kvm_run and initialize it.  This changes the ABI,
but as this particular ABI was unusable before this no users are affected.
