Subject: [PATCH 0/8] x86/fpu: Remove CR0.TS support
Date: Mon, 31 Oct 2016 15:18:41 -0700 [thread overview]
Message-ID: <cover.1477951965.git.luto@kernel.org> (raw)
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()
