[PATCH RFC v2 03/22] KVM: arm64: Move SVE state access macros after feature test macros

Mark Brown broonie at kernel.org
Fri Dec 22 08:21:11 PST 2023


In preparation for SME support move the macros used to access SVE state
after the feature test macros, we will need to test for SME subfeatures to
determine the size of the SME state.
