[PATCH 0/8] x86/fpu: Remove CR0.TS support

[Andy Lutomirski]

We don't do anything useful with CR0.TS anymore, so remove most of
our support for it.

I havne't meaningfully tested lguest because I can't get it to work
even without these patches.

Andy Lutomirski (8):
  fpu/init: Get rid of two redundant clts() calls
  fpu/bugs: Stop saving and restoring CR0.TS in fpu__init_check_bugs()
  x86/fpu: Remove irq_ts_save() and irq_ts_restore()
  x86/kvm: Remove host CR0.TS manipulation
  lguest: Remove CR0.TS support
  x86/fpu: #NM without FPU emulation is an error
  x86/fpu: Remove stts()
  x86/fpu: Remove clts()
