Subject: KVM: selftests: Add a "struct kvm_mmu_arch arch" member to kvm_mmu
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3d0e7595e81017558189d2252ae9453c57ab3436;p=thirdparty%2Fkernel%2Fstable.git

KVM: selftests: Add a "struct kvm_mmu_arch arch" member to kvm_mmu

Add an arch structure+field in "struct kvm_mmu" so that architectures can
track arch-specific information for a given MMU.

No functional change intended.
