Simplify the binding of the guest state to the CPU when returning to the host by storing a copy of the structure used to pass the state in the vCPU data and initialising it during guest setup rather than creating a new copy each time we exit the guest.
Signed-off-by: Mark Brown <broonie@kernel.org> --- Changes in v2: - Remove stale fp_state local. - Changelog updates. - Link to v1: https://lore.kernel.org/r/20240226-kvm-arm64-group-fp-data-v1-0-07d13759517e@kernel.org
