Dave Hansen 633d54c47a x86/fpu: Add xfeature_enabled() helper instead of test_bit() ... We currently use test_bit() in a few places to see if an xfeature is enabled. It ends up being a bit ugly because 'xfeatures_mask' is a u64 and test_bit wants an 'unsigned long' so it requires a cast. The *_bit() functions are also techincally atomic, which we have no need for here. So, remove the test_bit()s and replace with the new xfeature_enabled() helper. This also provides a central place to add a comment about the future need to support 'system xstates'.
