Yu-cheng Yu 524bb73bc1 x86/fpu/xstate: Separate user and supervisor xfeatures mask ... Before the introduction of XSAVES supervisor states, 'xfeatures_mask' is used at various places to determine XSAVE buffer components and XCR0 bits. It contains only user xstates. To support supervisor xstates, it is necessary to separate user and supervisor xstates: - First, change 'xfeatures_mask' to 'xfeatures_mask_all', which represents the full set of bits that should ever be set in a kernel XSAVE buffer. - Introduce xfeatures_mask_supervisor() and xfeatures_mask_user() to extract relevant xfeatures from xfeatures_mask_all.
