Merge branch 'for-next/sve-state' into for-next/core
* for-next/sve-state:
arm64/fp: Use a struct to pass data to fpsimd_bind_state_to_cpu()
arm64/sve: Leave SVE enabled on syscall if we don't context switch
arm64/fpsimd: SME no longer requires SVE register state
arm64/fpsimd: Load FP state based on recorded data type
arm64/fpsimd: Stop using TIF_SVE to manage register saving in KVM
arm64/fpsimd: Have KVM explicitly say which FP registers to save
arm64/fpsimd: Track the saved FPSIMD state type separately to TIF_SVE
KVM: arm64: Discard any SVE state when entering KVM guests
