[PATCH 0/2] KVM: arm64: Store a cpu_fp_state directly in the vCPU data

[Mark Brown]

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.
