commit 63753fac67e11fb6bac3d5c6a48bd319d9e612c2

x86: Store a per-cpu shadow copy of CR4
[ Upstream commit 1e02ce4cccdcb9688386e5b8d2c9fa4660b45389 ]
Context switches and TLB flushes can change individual bits of CR4.
CR4 reads take several cycles, so store a shadow copy of CR4 in a
per-cpu variable.
To avoid wasting a cache line, I added the CR4 shadow to
cpu_tlbstate, which is already touched in switch_mm. The heaviest
users of the cr4 shadow will be switch_mm and __switch_to_xtra, and
__switch_to_xtra is called shortly after switch_mm during context
switch, so the cacheline is likely to be hot.

commit 63753fac67e11fb6bac3d5c6a48bd319d9e612c2

x86: Store a per-cpu shadow copy of CR4
[ Upstream commit 1e02ce4cccdcb9688386e5b8d2c9fa4660b45389 ]
Context switches and TLB flushes can change individual bits of CR4.
CR4 reads take several cycles, so store a shadow copy of CR4 in a
per-cpu variable.
To avoid wasting a cache line, I added the CR4 shadow to
cpu_tlbstate, which is already touched in switch_mm. The heaviest
users of the cr4 shadow will be switch_mm and __switch_to_xtra, and
__switch_to_xtra is called shortly after switch_mm during context
switch, so the cacheline is likely to be hot.
