x86/fpu: Make init_fpstate correct with optimized XSAVE (2021-06-22 11:06:21 +0200)
----------------------------------------------------------------
Two more urgent FPU fixes:
- prevent unprivileged userspace from reinitializing supervisor states
- Prepare init_fpstate, which is the buffer used when initializing
FPU state, properly in case the skip-writing-state-components XSAVE*
variants are used.
