[PATCH v3 2/7] arm64/fpsimd: Track the saved FPSIMD state type separately to TIF_SVE

2022-08-15 Thread Mark Brown
When we save the state for the floating point registers this can be done in the form visible through either the FPSIMD V registers or the SVE Z and P registers. At present we track which format is currently used based on TIF_SVE and the SME streaming mode state but particularly in the SVE case
