Pull x86 FPU updates from Ingo Molnar: "The main changes in this cycle were: - do a large round of simplifications after all CPUs do 'eager' FPU context switching in v4.9: remove CR0 twiddling, remove leftover eager/lazy bts, etc (Andy Lutomirski) - more FPU code simplifications: remove struct fpu::counter, clarify nomenclature, remove unnecessary arguments/functions and better structure the code (Rik van Riel)" * 'x86-fpu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/fpu: Remove clts() x86/fpu: Remove stts() x86/fpu: Handle #NM without FPU emulation as an error x86/fpu, lguest: Remove CR0.TS support x86/fpu, kvm: Remove host CR0.TS manipulation x86/fpu: Remove irq_ts_save() and irq_ts_restore() x86/fpu: Stop saving and restoring CR0.TS in fpu__init_check_bugs() x86/fpu: Get rid of two redundant clts() calls x86/fpu: Finish excising 'eagerfpu' x86/fpu: Split old_fpu & new_fpu handling into separate functions x86/fpu: Remove 'cpu' argument from __cpu_invalidate_fpregs_state() x86/fpu: Split old & new FPU code paths x86/fpu: Remove __fpregs_(de)activate() x86/fpu: Rename lazy restore functions to "register state valid" x86/fpu, kvm: Remove KVM vcpu->fpu_counter x86/fpu: Remove struct fpu::counter x86/fpu: Remove use_eager_fpu() x86/fpu: Remove the XFEATURE_MASK_EAGER/LAZY distinction x86/fpu: Hard-disable lazy FPU mode x86/crypto, x86/fpu: Remove X86_FEATURE_EAGER_FPU #ifdef from the crc32c code
