Subject: KVM: arm64: vgic-v5: Move PPI caps into kvm_vgic_global_state
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2e83ac3b3b1a1b3b248a4af07efb19a1acb29845;p=thirdparty%2Flinux.git

KVM: arm64: vgic-v5: Move PPI caps into kvm_vgic_global_state

Constant vgic properties are usually kept in kvm_vgic_global_state,
but the vgic-v5 code does its own thing.

Move the ppi_caps data into the global structure, which has the
modest additional advantage of making it ro_after_init.
